Chapter 1
Introducing Software Virtualization Solution
Software Virtualization Solution (SVS) is a revolutionary approach to software
management. By placing applications and data into managed units called Virtual
Software Packages, Software Virtualization Solution lets you instantly activate,
deactivate or reset applications and to completely avoid conflicts between applications
without altering the base Windows installation.
Software Virtualization Solution is based on Altiris patents-pending core technology
known as the SVS File System Filter driver.
Software Virtualization Solution leverages the Altiris Extensible Management
Architecture of Notification Server, the Altiris Agent, and the Altiris Console.
This chapter contains the following topics:

Solving Problems with Software Virtualization
Solution
Software Virtualization Solution solves the following common application management
problems:
Provisioning and deprovisioning applications is disruptive to the user
and time consuming
With Software Virtualization Solution, you can easily deploy virtualized applications
without running an application install or uninstall on client computers. Application
availability is instantaneous—you can easily and immediately activate or deactivate your
applications by sending a single command to the client computer. The user is not
required to have system rights to run an installation, and you don’t have to worry about
restarting when you activate or deactivate an application. The solution can also register
any services that the application installed with the Windows Service Control Manager,
which then loads the service so that the application is fully functional.
Recovering a damaged application is time consuming
Rather than repairing or recovering a damaged application, you can simply reset it to
the original deployed condition. Application resets can be performed instantly or on a
schedule. An application can be reset whether the client computer is connected to the
network or not. Resetting a virtual application does not damage other applications
installed on the computer.
Conflicting applications are difficult or impossible to manage
Software Virtualization Solution ensures applications use the correct files and registry
settings without modifying the operating system and interfering with other applications.
Software Virtualization Solution
9
This provides numerous benefits, including improved reliability and flexibility. Example:
When installing new software or application updates, administrators might inadvertently
replace newer .DLLs with older .DLLs, which can cause immediate problems between
applications sharing those .DLLs, causing application failure or reintroducing security
holes that previously were patched. With Software Virtualization Solution, you can stop
worrying about “DLL hell.”
Other benefits include allowing different versions of the same application to co-exist on
the same computer. Also, virtualized applications will never corrupt an operation system.
Migrating to new application versions requires significant testing and
planning; takes a long time to execute and rollback is difficult
Rolling out new versions of an application requires significant time to test for conflicts
and reprovisiong lab testing computers. Software Virtualization Solution simplifies predeployment testing, accelerates the deployment cycle, and reduces post-deployment
support costs. With Software Virtualization Solution, you can host multiple versions of
an application on the same system without conflicts between older and newer files.
Even phased rollouts are greatly accelerated because rollback can occur immediately at
any time. Once the transition from an older application to a newer application is
complete, simply deactivate and remove the older version.
Software Virtualization Solution Benefits
Integrates With Altiris® Extensible Management Architecture™
Software Virtualization Solution integrates with Altiris® Extensible Management
Architecture™ (EMA™), so you benefit from native integration with Altiris service
management, asset management, and systems management solutions. Take advantage
of reports and policies that let you quickly troubleshoot and better forecast potential
system problems. Example: Altiris pre-packaged Web Reports™ allow you to drill down
for detailed information about your environment.And not only does EMA let you leverage
your existing investment in Altiris solutions, it also makes it easy to extend capabilities
as your business grows and your business needs change.

How Software Virtualization Works
An application or set of data is virtualized by using a capture process that creates a
Virtual Software Package (VSP). A VSP contains all the files and registry settings of the
application or data. A VSP can be used on a client computer that has the Software
Virtualization Agent. The VSP is installed to a special area on the hard drive. After the
VSP is activated through the Software Virtualization Agent, the application becomes
visible along with its files, folders, and settings. Even though it is a “virtual” application,
it looks and behaves like any other application to the end user.
This section describes the following topics:
z
Software Virtualization and Redirection (page 16)
z
Virtual Software Package Architecture (page 18)
z
Layer Architecture (page 19)
z
Layer Actions and States (page 20)
z
Software Virtualization and Variablization (page 21)
Software Virtualization and Redirection
Each Virtual Software Package (VSP) is managed by SVS as a distinct entity. When
activated, VSPs are like “layers” over the base Windows operating system so the system
appears to contain the aggregate contents of the base operating system plus the active
VSPs.
When a VSP is imported onto a computer, the contents of the VSP (both files and
registry settings) are placed in a folder in a special protected SVS area on the hard dive,
referred to as the SVS redirection area.
When a VSP is imported on a client computer, the contents of the VSP are placed in the
redirected folder, such as C:\fslrdr\1. When the VSP is activated on a client computer,
the contents of the VSP are made available to the user. The files and settings appear to
the user in the location they would be in if the application had been installed on the
computer.
Example: You have a VSP for Mozilla Firefox. When the Firefox VSP is activated, all the
contents of the VSP are “layered” over the base file system and registry to make it
Software Virtualization Solution
16
visible to the user. The user then sees it’s appropriate folders, files, registry settings,
and shortcuts. When the contents are made visible, they are not displayed in the hidden
area, but they are displayed in the locations that the user would see them had Firefox
been installed on the computer. Example: Even though the Firefox application file may
physically be located at
C:\fslrdr\1\PROGRAMFILES\Mozilla Firefox\firefox.exe
to the user, it is visible as
C:\Program Files\Mozilla Firefox\firefox.exe
Software Virtualization Solution accomplishes this by using a filter that intercepts
requests to the file system and registry, and when needed, redirects requests to the
active VSPs. Software Virtualization Solution uses the SVS File System Filter Driver to
aggregate the real and virtual file systems into one view for the end-user. The SVS File
System Filter Driver is the main component of the Software Virtualization Agent. The
Software Virtualization Agent must be installed on any computer that you want to use
VSPs on.
Example: The Firefox VSP is active. When a user browses to C:\Program Files\, all the
subfolders in the actual file system folder appear, but the filter driver also looks at any
active VSPs, and in this case, also displays the folder C:\Program Files\Mozilla Firefox.
With redirection, SVS can maintain discrete settings and file versions for different
applications on a single system. By working with VSPs, a required version of a file will
never be overwritten. This is particularly important when you are working with Dynamic
Link Libraries (DLL). Incompatible .DLL files are known to cause application instability.
By using applications within VSP, you can ensure that applications use its own set of
.DLL files without interfering with the rest of the operating system or other applications
running at the same time.
This extends not only to files that relate to applications, but also to registry settings and
data files.
Software Virtualization Solution

Virtual Software Package Architecture
A Virtual Software Package (VSP) is a generic term used for a set of captured data in its
complete life-cycle while being managed by SVS. A VSP can be in one of two formats: a
“Virtual Software Layer” or a “Virtual Software Archive” file.
Virtual Software Layers
When an application or set of data is captured into a Virtual Software Package,
everything that is captured is contained in a “layer.” The “layer” represents all the files
and registry settings that make up the virtualized application or data.
Typically, one layer is created for one application. However, one layer can contain
multiple applications. Each layer is managed as a single entity.
The files and settings captured in a layer are stored in the SVS redirection area on the
computer’s hard drive. However, when a layer is active, all files and settings appear in
the system just as they would if the application or data was installed on the computer.
This is accomplished through redirection using the SVS File System Filter Driver.
Virtual Software Archive (VSA) files
If you want to make a layer portable so that it can be used on another computer, the
contents of the layer are exported to a single Virtual Software Archive (VSA) file. These
archive files have a .VSA extension.
VSA files can then be copied or deployed to other computers. To make the contents of
the VSA usable on a computer, the VSA must be imported using the Software
Virtualization Agent. When a VSA is imported on a computer, the layer (the files and
registry settings in the VSA) are installed to the SVS redirection area on the client
computer’s hard drive.
Virtual Runtime Archive (VRA) files
Software vendors can create a Virtual Software Package (VSP) that includes their
product in a Virtual Runtime Archive (VRA) file. This package includes the vendor’s
product plus the basic components of SVS that are needed to use the vendor’s product.
This lets developers distribute their software as a VSP, even when a customer does not
own SVS.
Software Virtualization Solution
18
Note
You can only create .VRA files with Wise Installation Studio 7.0 SP1 or later. For details,
see the Wise Virtual Package Editor Reference in Wise Installation Studio 7.0 SP1 or
later.
For information see Using Software Virtualization Solution in Runtime Mode on page 23.
Layer Architecture
There are two components or sublayers in a layer:
Read-only sublayer
Contains all captured files and settings.
Writeable sublayer
Contains any files or settings that are added or changed by
a user of a layer.
Read-only
Sublayer
Layer
Writeable
Sublayer
VSP
Virtual
Software
Package
.VSA
Virtual
Software
Archive
Example: You create a layer for Firefox. As a person uses Firefox, they may make some
changes to the program. They may select a unique home page, add bookmarks, or
change the original security settings. They may also install a browser plug-in. Those
user changes are stored in the Writeable sublayer. The original files and settings are
maintained in the Read-only sublayer.
Having these distinct sublayers is useful in being able to reset a layer. When a layer is
reset, any data added by a user is deleted, and the layer is returned to its original
configuration.
Example: If a user’s Firefox application ever becomes damaged, you can simply reset
the layer to restore it to the way it was first deployed. The application does not have to
be uninstalled/reinstalled.
Resetting layers also maintains specific versions and configurations of applications
across your network. You can control how the applications are installed and configured
on client computers.
Note
The two sublayers currently apply only to virtualized application layers, not data layers.
Software Virtualization Solution
19
Caution
When you reset a layer, any data that is written to the Writeable sublayer will be lost.
For information, see Resetting Layers (page 45).
Layer Actions and States
You can perform the following actions on layers:
Name
Description
Layer Actions
Import
The layer files in a VSA file are installed in the hidden SVS
redirection area on the client computer. However, imported files
are not visible until the layer is activated.
Activate
The layer files that have been imported on a client computer are
made visible to the user. Activation and deactivation occur almost
instantaneously.
Deactivate
The imported layer files are hidden from the user but are kept on
the computer.
Note
You cannot deactivate a layer while a process is running from that
layer. For information, see Deactivating Layers with Services
Running (page 45).
Deactivate
(Force)
The layer is forcefully deactivated by killing all the running
applications from that layer. This might cause undesired results.
Delete
The imported layer files are removed from the computer.
Delete (Force)
The layer is forcefully removed by killing all the running
applications from that layer. This might cause undesired results.
Reset
Deletes all of the user’s profiles in a layer that were added or
changed. The data in the Writeable sublayer is deleted, leaving
only the files in the Read-only sublayer. See Resetting Layers
(page 45).
Note
Data layers cannot be reset. Hence, “Reset”, “Reset and Activate”
and “Reset and Deactivate” are not available for data layers.
Reset (Force)
Deletes all of the user’s profiles in a layer that were added or
changed, killing all the running applications from that layer. This
might cause undesired results.
Layer States
Activated
The imported layer files are made visible to the user.
Deactivated
The imported layer files are hidden from the user.
Combination
of Actions and
States
Import and
Activate
Software Virtualization Solution
The layer files are placed in the SVS redirection area on the client
computer and are made visible to the user.
20
Name
Description
Reset and
Activate
The layer files are reset to their original imported state by
deleting all user data and changes (Writeable sublayer), and the
layer is visible to the user.
Reset and
Deactivate
The layer files are reset to their original imported state by
deleting all user data and changes (Writeable sublayer), and the
layer is not visible to the user.
Software Virtualization Workflow
The following diagram illustrates a typical Software Virtualization workflow:
1.
Using Software Virtualization Solution tools (SVS Admin), capture an application
into a layer.
2.
To make the layer portable, export the layer to a Virtual Software Archive (VSA) file.
3.
Deploy the VSA to a client computer.
4.
Import the VSA into a layer on the client computer.
5.
Activate the layer to access the application.
Software Virtualization and Variablization
Many applications have specific environment settings for file paths, paths in registry
values, MSI paths, and so forth. To make VSPs portable across computers, many
application settings and data layer properties are variablized by Software Virtualization
Solution.
Example: SVS uses common system variables to substitute for well-known locations on
a Microsoft Windows based installation, such as WINDIR as a substitute for the
“Windows” folder. This provides seamless compatibility with systems that may not be
using the standard folder structure, such as systems that have moved their “My
Documents” folder or that have renamed OS folders.
Example: If you have a VSP for My Documents, it may be on C drive on one computer
but on D drive on another computer. Variablization allows the data layer to work
correctly on both computers. For information, see View Variables used in a Layer
(page 57).

What Can be Virtualized?
You can virtualize applications and collections of data.
Application Layers
Most every application can be virtualized, including office applications, databases,
Internet browsers, media, and spyware utilities. Applications function normally when
virtualized by SVS. All functionality and configuration options are available to the user.
Data Layers
You can also redirect user data to be stored within a layer. (Example: All files created
with a .DOC extension can be stored within a layer, letting users easily group their
documents together. Users can also define folders in the same way.) (Example: The “My
Documents” folder can be redirected to a data layer.) By giving multiple paths and
directing that content to a data layer, you can manage all user content invisibly. Coupled
with the layer import/export function, this lets a user copy not only an application from
one machine to another, but also all of their customizations and files. By having data
files in their own layers, those files are protected when application layers are reset and
writeable data in those layers are lost. For information, see Creating and Using Virtual
Data Layers (page 42).
What Cannot be Virtualized?
Some applications and file types do not work well virtualized at this time. For
information, see Software Virtualization Solution Limitations (page 26).
How are Applications and Data Virtualized?
Virtualized applications and data are captured into Virtual Software Packages using the
capture tools Software Virtualization Solution Admin (SVS Admin), an SVS Control Panel
Applet, or through SVSCMD command line functionality that is installed with SVS Admin.
Virtual Software Packages contain all the files and registry settings required for an
application to run.
How Can Virtual Software Packages be Used?
Virtual Software Packages are highly portable and can be easily used between different
computers and Windows operating system versions. The virtualization technology is
Software Virtualization Solution
22
invisible to the user, the applications, and operation system, yet virtualized applications
and data are visible system-wide and execute normally.
You can use Virtual Software Packages in the following environments:
z
Using Software Virtualization Solution Stand-alone
z
Using Software Virtualization Solution in an Altiris® Notification Server Environment
z
Using Software Virtualization Solution in an Altiris® Deployment Solution™
Environment
Using Software Virtualization Solution Stand-alone
You can use Virtual Software Packages in a stand-alone environment on Windows-based
computers. To use Virtual Software Packages, install the Software Virtualization Solution
Admin tool on a computer and then create or import existing Virtual Software Packages.
For information, see Getting Started with Virtual Software Layers and Archive Files
(page 31).
You can use the Software Virtualization Solution for Personal Use version to create and
use your own virtual layers in a single-computer environment.
You can also make VSA files available to network users by using network shares, login
scripts, SMS, and so forth.
For information, visit the Juice at http://www.altiris.com/juice.
Using Software Virtualization Solution in an Altiris® Notification
Server Environment
Using the Notification Server-based Software Virtualization Solution, you can remotely
deploy Virtual Software Packages to client computers on managed computers on your
network. You can also remotely control the state of the Virtual Software Packages on
client computers and view reports about Virtual Software Packages deployment and
usage. Software Virtualization Solution is also integrated with Altiris® Inventory
Solution™ and the Altiris® Software Delivery Solution™ Software Portal. For
information, see Using Software Virtualization Solution in a Notification Server
Environment (page 99).
Using Software Virtualization Solution in an Altiris® Deployment
Solution™ Environment
Using Software Virtualization Solution and Deployment Solution, you can remotely
deploy Virtual Software Packages to client computers on your network. For information,
see Using Software Virtualization with Altiris® Deployment Solution™ (page 152).
Using Software Virtualization Solution in Runtime Mode
Runtime Mode lets application developers distribute their software in an Altiris VSP, even
when a customer does not own SVS.
Software vendors using Wise Installation Studio (7.0 SP1 or later) can create a special
type of VSP that includes their application as a Virtual Runtime Archive (VRA) file.
These VSPs include an automated installation of the SVS Agent that runs in runtime
mode.
A .VRA’s package can do the following:
z
Software Virtualization Solution
Install the SVS Agent (if needed) in Runtime Mode.
23
z
Import the .VRA file.
z
Activate the layer.
When the SVS Agent is licensed it is in Standard Mode and all SVS functions are
available on all layers. When the SVS Agent is configured in runtime mode it can
perform limited SVS actions.

Note
When the SVS Agent is in Runtime mode, it will not allow any Data Layer functions.
If you inadvertently have a client computer running the SVS Agent in Runtime Mode,
you can add a valid license that will put the SVS Agent into standard mode.
A license can be added or removed from the SVS Agent and the data will not be
affected, so the SVS Agent can change its status back and forth between Standard Mode
and Runtime Mode without risk of data loss. Layers are not deleted when the SVS
Agent’s mode changes.
Note
You can only create .VRA files with Wise Installation Studio 7.0 SP1 or later. For details,
see the Wise Virtual Package Editor Reference in Wise Installation Studio 7.0 SP1 or
later.

How does SVS Work with Recovery Solution and other Backup Products? (page 25)
What Demands does SVS place on the Physical
Network?
SVS does not add any unique demands on a network. When used in a Notification Server
environment, the only demand is during the initial package delivery, the same as with
Software Delivery Solution. All of the same tools available in Software Delivery Solution
(multicasting, bandwidth throttling, automatic resume of failed transfer, and so on) are
available to you to maximize bandwidth usage. However, Software Delivery Solution is
not required (both products use the same back-end architecture for management).
Are there Minimum Bandwidths Requirements for
Deploying Virtualized Applications to Off-site
Users?
There is no “recommended” minimum bandwidth, although the Altiris framework
provides tools to help make distributions to remote users easier (see What Demands
does SVS place on the Physical Network?), including the ability to require a minimum
bandwidth before attempting a download. VSPs can be deployed on Package Servers
and Deployment Servers.
Are there Requirements for Microsoft Active
Directory to Support SVS?
There are no additional configuration requirements for SVS to work with Microsoft Active
Directory. At this time, there is no specific interaction between Active Directory and SVS.
Does SVS Use any of the Native Microsoft MSI
Methods for “Application distribution”?
You can use “Live Capture” to deploy an .MSI using Software Delivery Solution. When
doing this, a capture is started on the client before the install runs and ended after the
install ends. The result is a virtualized application. This allows customers to leverage
their existing .MSI libraries but results in dissimilar instances of the VSP on every
workstation.
However, for greater manageability, we recommend performing a single installation in a
controlled environment, then optimizing and testing a standardized VSP to deploy to
every client computer.
How does SVS Work with Recovery Solution and
other Backup Products?
If a client computer is protected using Recovery Solution or a similar backup application,
the SVS redirection area shows in the Recovery Solution name space, and can be part of
snapshots. Layers can be successfully restored through a Full System Recovery or full
Rollback. Using these methods, the entire redirection area with accompanying registry
settings are restored and will function correctly.
However, full functionality is not possible if only files from the redirection are restored.
For this reason, a simple restore of files from the redirected folder (Example: C:\fslrdr,
Software Virtualization Solution
25
C:\fslrdr\1) should not be done through Recovery Solution. Instead, the whole system
needs to be restored together.

z
How SVS Affects Local Drive Space Usage in Windows (page 26)
Are there Special Requirements for Running
Virtualized Applications?
SVS requires no additional hardware requirements. You only need to install the Software
Virtualization Agent. The SVS File System Filter Driver is around 160 KB and consumes
less than 1 MB of working memory under heavy load.
How SVS Affects Local Drive Space Usage in
Windows
SVS affects drive space utilization in a way that may not be obvious. Layer files and
directories are stored in a redirection area. The drive where this area is located will show
space being utilized. In the case where the redirection area is located on the same drive
as the applications, space utilization will appear as normal. When the redirection area is
located on a different drive from where the applications are installed, the application
drive will appear to have more free space than expected while the redirection-area drive
will show more used space.
When the hidden redirection area that layers are stored on is on the client computer’s C
drive, and the default redirect area is left unchanged, the C drive must have enough free
space to accommodate all desired layers, and the drive space usage statistics for the C
drive will reflect these files.
However, if the layer is pointing to the D drive, the files are still physically on the C drive,
not the D drive. Example: Suppose you have a layer for an application like MS Office
that is pointing to a D drive (used as an “apps drive”). Drive space usage statistics for
the D drive will not reflect the files, but statistics for the C drive will.
Note
The redirect area is not confined to only the C drive. It can also be moved to a NTFS or
FAT drive. However, for security reasons, we recommend that the redirect area reside in
an NTFS file system.
Software Virtualization Solution Limitations

SVS File System Filter Driver and Running Windows in Safe Mode (page 27)
Software Virtualization Solution
26
What Things Cannot or Should not be Virtualized?
Some applications do not work well virtualized at this time. These include drivers, virus
checkers, file encryption products, OS patches, computer management agents, and
applications that have dedicated drivers (Example: client firewalls).
You cannot encrypt files that are stored in a data layer. If you encrypt a folder that is in
the layer, the folder is moved to the base. When files are moved to that folder, you get
an error that the files cannot be encrypted and you can move them into the layer only as
unencrypted files.
SVS File System Filter Driver and Running Windows in Safe
Mode
The SVS File System Filter Driver is not loaded when a computer is booted into Windows
Safe Mode. Any diagnostic or recovery utilities that could be usable in safe mode to
diagnose and recover a system should not be included in a layer. These utilities will not
be available if they have been added to the system through a layer, thus possibly
making it too late to recover after they become necessary.
Software Virtualization Solution Glossary
File Delete Entries and Registry Delete Entries
When an application that is running from a layer deletes a file or registry setting outside
of the layer, the file or setting is not actually deleted, but hidden while the layer is
active. These hidden files and registry settings are called file delete entries and registry
delete entries.
Global Exclude Entry
You can configure a system to exclude file types or folder locations on a global level. This
is done so that a file will not be redirected by the SVS File System Filter Driver to the
layer. Instead, the file is saved to the core file system. These entries can be file type
extensions or directory locations.
Layer Exclude Entry
You can configure a layer to exclude file types or folder locations from capture. This is
done so that a file will not be redirected by the SVS File System Filter Driver to the layer.
Instead, the file is saved to the core file system.
Runtime Mode
Runtime Mode lets application developers distribute their software in an Altiris VSP, even
when a customer does not own SVS.
Software vendors using Wise Installation Studio (7.0 SP1 or later) can create a special
type of VSP that includes their application as a Virtual Runtime Archive (VRA) file.
These VSPs include an automated installation of the SVS Agent that runs in runtime
mode.
The SVS Agent can move between Standard Mode and Runtime Mode without risk of
data loss; layers are not deleted when the license mode changes.
When the SVS Agent is in Runtime Mode, it can perform limited SVS actions.
Software Virtualization Solution
27
Note
You can only create .VRA files with Wise Installation Studio 7.0 SP1 or later. For details,
see the Wise Virtual Package Editor Reference in Wise Installation Studio 7.0 SP1 or
later.
Standard Mode
Standard Mode is a term used when it is necessary to distinguish the Agent’s status as
being either in Standard Mode or Runtime Mode. In Standard Mode all SVS functions are
available on all layers.
The SVS Agent can move between Standard Mode and Runtime Mode without risk of
data loss; layers are not deleted when the license mode changes.
SVS File System Filter Driver
The SVS File System Filter Driver is a Windows NT technology that manages the data
flow between applications and the operating system.
Software Virtualization Agent
The agent software on a client computer containing the SVS File System Filter Driver
that manages Virtual Software Packages.
Software Virtualization Solution Admin (SVS Admin)
The Software Virtualization Solution Windows-based tool used to create, edit, and
export Virtual Software Layers. You can also use SVSAdmin to manually manage layers
on a client computer.
SVS Applet
The SVS applet is installed when you install the Software Virtualization Agent. It is
available from the Control Panel and lets you create, import, export, and manage SVS
layers.
SVS redirection area
When a VSP is imported onto a computer, the contents of the VSP (both files and
registry settings) are placed in a folder in a special protected SVS area on the hard dive,
referred to as the SVS redirection area. The SVS redirection area is a folder named
C:\fslrdr.
SVS Task Server Plug-in
SVS Task Server Plug-in adds functionality to the Altiris® Task Server that lets you
manage SVS layers on client computers. The Task Server is an infrastructure component
that provides task sequencing and automation for Altiris solutions.
Virtual Runtime Archive (VRA)
Software vendors can create a package that includes their product in a Virtual Runtime
Archive (VRA) file, plus the basic components of SVS that are needed to use the
vendor’s product. This lets developers distribute their software in an Altiris Virtual
Software Package (VSP) even when a customer does not own SVS.
Software Virtualization Solution

Note
You can only create .VRA files with Wise Installation Studio 7.0 SP1 or later. For details,
see the Wise Virtual Package Editor Reference in Wise Installation Studio 7.0 SP1 or
later.
Virtual Software Package (VSP)
The generic term for all the files that makes an application work, including applications
and data, files and registry settings. A Virtual Software Package can be in one of two
formats: a “Virtual Software Layer” or a “Virtual Software Archive” file.
Virtual Software Layer
A Virtual Software Layer is the base collection of files and registry definitions and data
for a Virtual Software Package.
When a layer is imported to a client computer, the data from the layer is placed in a
hidden SVS redirection area. When a layer is activated, the contents of the layer are
overlaid over the base file system and registry and the contents of the layer appear as if
it had been installed.
There are two kinds of layers: Application layers and Data layers.
Layers contain two sublayers: the Read-only sublayer and the Writeable sublayer.
Virtual Software Archive (VSA)
The portable version of a Virtual Software Package. A Virtual Software Archive contains
the compressed data from a layer in a single portable file that can be deployed and
imported on client computers.
Virtual Software Package resource object
The deployed payload when deploying VSA files in a Notification Server environment.
These are similar to Software Delivery Packages used with Software Delivery Solution.

Exercise Scenario
The exercises below will guide you through the process of creating and using a layer for
Mozilla Firefox. If you want to follow the exercise, download the Firefox setup file
(Firefox Setup ver.exe) from http://www.mozilla.org/products/firefox/.
Software Virtualization Solution
31
Configuring a Base Computer
A base computer is the computer that you will capture application and data files on. The
installed application and data files and settings will be captured into Virtual Software
Layers.
The base computer should have a clean installation of your Windows operating system
and little else. This computer should not have background processes or programs
running that will get captured into your layers. We recommend that your base computer
not be running antivirus or other computer management programs, and if possible, not
have an active Internet connection.
We suggest creating layers on a virtual computer. This lets you easily disconnect the
computer from the network and reset the computer after each capture so you have a
clean operating system.
Exercise
For this exercise, you will want to use a computer that does not currently have Firefox
installed on it, but has Internet Explorer.
Installing the Software Virtualization Agent and
Admin Tool on a Base Computer
The Software Virtualization Agent can be installed with the Software Virtualization
Admin tool (SVS Admin) and used to create and manage Virtual Software Layers and
Virtual Software Archive Files. You will install the Software Virtualization Agent and SVS
Admin on your base computer.
You can access the setup file from anywhere. Because we recommend that you not have
an active Internet connection, the setup file should be local.
For client computer prerequisites, see Prerequisites for Getting Started tasks (page 31)
and Software Virtualization Solution Security (page 80).
Installing SVS Agent and Admin
You can download installation setup files from:
http://www.altiris.com/download.aspx

Creating a Virtual Software Layer Using SVS Admin
After you have installed SVS Admin, you can create Virtual Software Layers. In order to
create a layer for an application, you will “capture” the installation of the application. All
installed files, registry settings, and application settings will be captured and stored in
the layer.
To create a Virtual Software Layer
In the following steps, you will create a new layer for Mozilla Firefox.
1.
On the base computer, make sure you have access to the setup files for the
application you will be creating a layer for. Example: Firefox Setup ver.exe.
2.
On the base computer, open the SVS Admin tool by clicking the SVS Admin icon on
the desktop.
3.
Select File > Create New Layer.
4.
Choose Install application and click Next.
5.
Name the layer. Example: Firefox 1_5.
The maximum name length is 50 characters.
6.
Click Next.
7.
Select the capture method.
For this exercise, choose Single program capture.
For information on capture options, see Creating Virtual Software Layers (page 39).
8.
Click Browse.
9.
Navigate to the setup file. Exercise: Firefox Setup ver_exe.
10. Click Next.
11. Click Finish.
The animated capture icon (yellow lightning) appears in the system tray. The icon is
animated (top to bottom) signifying that you are capturing.
12. Follow any dialogs to install the application.
In most cases, when the application installation is complete, the capture is
automatically ended and the layer is listed in SVS Admin.
However, in the Firefox exercise, when the installation is complete, you have the
option to Launch Mozilla Firefox now. If this option is selected when you click
Finish, Firefox will load and because it was loaded by the installer, SVS will still be
in capture mode. If this option is cleared when you click Finish, the capture mode
will terminate with the installer and the capture process is finished.
13. For the exercise, keep the Launch Mozilla Firefox now option selected and click
Finish.
The first time you launch Firefox, you are given configuration options. Since you are
still in capture mode, these configuration settings will be stored in the Read-only
sublayer.
If you were not in capture mode when you launched Firefox for the first time, but
simply launched it through the layer, these settings would be stored in the Writeable
sublayer. (For information about sublayers, see Layer Architecture (page 19).)
Software Virtualization Solution
33
14. Select an import option and click Next.
15. Select the Home Page options and click Next.
Because you are still in capture mode, this Home Page setting will be stored in the
Read-only sublayer.
16. Select default browser settings.
The default browser setting will determine if Firefox is the default browser when the
Firefox layer is active. This setting will only apply when the Firefox layer is active.
Example: You may have Internet Explorer previously set as the default browser. If
you make Firefox the default browser, then when the Firefox layer is active, Firefox
will be the default browser. When the Firefox layer is not active, Internet Explorer
will be the default browser.
For this exercise, make Firefox the default browser by clicking Yes.
Firefox is now installed and running and you are still in capture mode. You can either
continue to manually configure Firefox or you can end the SVS capture.
17. For this exercise, terminate the capture now by closing Firefox.
When Firefox is closed, the capture is terminated, the capture icon disappears from
the system tray, and the Firefox layer is now listed in SVS Admin.
Information about modifying layers is provided in Modifying a Layer (page 35).
Testing Layers
After you have created a layer, you can test it to make sure it functions properly. To test
a layer, you can manually activate and use the layer on a computer. For information, see
Testing, Activating, and Deactivating Layers on page 34.
To test portability, you should test the layer on another computer. This ensures that
everything needed to run the program was captured into the layer.
Testing, Activating, and Deactivating Layers
When a layer is created, it is activated by default. When a layer is activated, that means
that all the contents of the layer are visible.
To activate or deactivate a layer
1.
2.
In SVS Admin, do one of the following:
„
Highlight a layer and click File.
„
Right-click a layer.
Click either Activate or Deactivate.
When a layer is active, the layer name is displayed in bold type.
Using the SVS Admin tool, you can activate and deactivate layers and test that the layer
is functioning properly.
Example: When Mozilla Firefox is installed, by default a shortcut to the application
appears on the Windows Desktop. When the layer is activated, the shortcut is visible. A
Short cut is also displayed in the Start > Programs list.
Software Virtualization Solution
34
When a layer is deactivated, the application components are hidden. The shortcut will
not be displayed on the Windows Desktop or Start > Programs list, and the files are
not viewable in the file system.
To test the active Firefox layer
1.
2.
3.
Launch Firefox:
„
Click the Mozilla Firefox shortcut icon on the desktop.
„
Select Start > Programs > Mozilla Firefox > Mozilla Firefox.
Verify that the application files are viewable in the file system:
a.
Open Windows Explorer.
b.
Browse to C:\Program Files\Mozilla Firefox.
Verify that Firefox is the default browser:
a.
Open Windows Explorer.
b.
Select Tools > Folder Options.
c.
Click the File Types tab.
d.
Scroll down and click the HTML extension.
The default application for HTML files is listed by “Opens with:”. If you made
Firefox the default browser, it will be listed.
To deactivate and test the deactivated Firefox layer
1.
In SVS Admin, right-click the Firefox layer and click Deactivate Layer.
2.
Verify that the following shortcuts are no longer virtualized:
3.
„
The Mozilla Firefox shortcut icon on the desktop.
„
The Start > Programs > Mozilla Firefox folder.
Verify that the application files are hidden in the file system:
a.
Open Windows Explorer.
b.
Browse to C:\Program Files.
The \Mozilla Firefox folder should no longer be virtualized.
4.
Verify that Firefox is not the default browser:
a.
Open Windows Explorer.
b.
Select Tools > Folder Options.
c.
Click the File Types tab.
d.
Scroll down and click the HTML extension.
The default application for HTML files is listed by “Opens with:”. Firefox will not be
listed. The default program before you installed Firefox will be listed.
Modifying a Layer
You can modify layers to add or remove files, settings, and so on. Example: You can add
bookmarks to or change the default security settings in the Firefox layer.
Software Virtualization Solution
35
When you modify a layer, you can make changes to the Read-only sublayer or the
Writeable sublayer. (For information about sublayers, see Layer Architecture on
page 19.)
Changes to the Read-only sublayer are permanent, whereas changes to the Writeable
sublayer will be deleted if the layer is ever reset.
Making Layer Changes in the Read-only Sublayer
To make permanent changes to the Read-only sublayer, use the update existing layer
feature. For information, see Updating Layers (page 46).
Making Layer Changes in the Writeable Sublayer
To make changes to the Writeable sublayer, simply activate the layer, and make any
desired changes.
For the Firefox exercise, do the following:
1.
Launch Firefox.
2.
Select Tools > Options.
3.
Click Content.
4.
Clear the Enable Java and Enable Javescript check boxes.
5.
Click OK.
The Java settings are stored in the Writeable sublayer and will be deleted if the layer is
reset.
Note
You can also edit the Writeable sublayer through the SVS Admin.
Resetting a Layer
When a layer is created, the data captured is stored in a Read-only sublayer (see Layer
Architecture on page 19). If a user makes any changes to the application/data, that data
is stored in a Writeable sublayer. You can reset the layer, which deletes all the data
added by the user (writeable data) and maintains the original read-only data.
For information, see Resetting Layers (page 45).
To manually reset the Firefox layer
1.
In SVS Admin, right-click the Firefox layer.
2.
Click Reset Layer and click Yes.
This deletes all data in the Writeable sublayer.
For the Firefox exercise, when you launch Firefox, the Java settings are reset to
enabled.
Exporting a Layer to a Virtual Software Archive File
After you have created and configured a layer, you can export it to a portable Virtual
Software Archive file (VSA). You can then share the VSA file or include it in a Notification
Software Virtualization Solution
36
Server Virtual Software Package to deploy to network users using Software
Virtualization Solution in Notification Server.
To export a layer to an archive VSA file
1.
In SVS Admin, right-click the layer and click Deactivate Layer.
2.
If this layer is to be distributed to other users, you may now want to Reset the layer
to remove existing user-specific information.
3.
Right-click the layer and click Export Layer.
4.
Select a filename and location to save the file. Example: C:\archives\Firefox1.5.vsa.
5.
Click OK.
All the contents of the layer are exported to the VSA file.
Importing VSA Files
Using SVS Admin, you can import an existing VSA file to make the layer available
through the SVS Agent.
To manually import a VSA archive file
1.
Copy an existing VSA file to a place you can access it from.
2.
In SVS Admin, select File > Import from Layer.
3.
Browse to the VSA file you want to import.
4.
Click Open.
The layer appears in SVS Admin.

Creating Virtual Software Layers
You can create three different kinds of Virtual Software Layers:
Application layer
All installed files, registry settings, and application settings will
be captured and stored in the layer.
Data layer
Data files are captured and stored in a dedicated data layer.
Empty layer
An Empty layer is an application layer without an application
installed into it. Nothing is initially captured but you can edit the
layer manually. There is no functional difference between
creating an application layer by capture versus creating an
empty layer and then updating it by capturing an application
install.
The following topics explain the following tasks:

Caution
Layers must not have the following characters in the layer name: & < > “ ' .
Creating Virtual Application Layers
To create a layer for an application, you will “capture” the installation of the application.
All installed files, registry settings, and application settings will be captured and stored
in the layer.
To create a Virtual Software Layer
1.
On the base computer, make sure you have access to the setup files for the
application you will be creating a layer for.
2.
On the base computer, open the SVS Admin tool by clicking the SVS Admin icon on
the desktop.
3.
Select File > Create New Layer.
4.
Choose Install application and click Next.
5.
Name the layer. Exercise: Firefox 1_0_7.
The maximum name length is 64 characters.
Caution
Layers must not have the following characters in the layer name: & < > “ ' .
6.
Software Virtualization Solution

7.
Select the capture method.
There are two methods of capturing an application:
Single
program
capture
Only the changes during the installation of a specified program
will be captured. Using this method, you select an application
setup file. The capture automatically begins when the setup is
started and the capture is automatically ended when the setup
is completed. During this capture, only changes made for the
selected application will be captured. Any other activity on the
computer will be ignored. This is the preferred method of
creating virtual software layers.
If an application is installed through a packaging tool, such as
Wise or InstallShield, SVS tracks the initial package process as
well as any client instances of msiexec.exe. All client instances
of msiexec.exe and accompanying service instances are
captured as long as they are running, whether or not the
original packaged .EXE terminates. See To create a layer using
Single Program Capture (page 41).
Caution
All processes that were started by the application (Example: a
system tray application) must be exited before the capture
process will complete.
Global
capture
All changes made to the computer during the capture process
will be saved into the layer. This option is useful in capturing
default application settings, shortcuts, or application updates
after an installation is complete. You can also combine multiple
applications into a single layer. See To create a layer using
Global Capture (page 41).
To create a layer using Single Program Capture
1.
Choose Single program capture.
2.
Click Browse.
3.
Navigate to the setup file. Example: Firefox Setup 1.0.7.exe.
4.
Click Next.
5.
Click Finish.
6.
The animated capture icon (yellow lightning) appears in the system tray. The icon is
animated (top to bottom) signifying that you are capturing.
7.
Follow any dialogs to install the application.
8.
When the application is complete, the capture is automatically ended and the layer
is listed in SVS Admin.
To create a layer using Global Capture
1.
Select the Global capture method.
2.
Click Next.
3.
Click Finish.
Software Virtualization Solution
41
The animated capture icon (yellow lightning) appears in the system tray. The icon is
animated (top to bottom) signifying that you are capturing.
4.
Install the application. Example: Run Firefox Setup 1.0.7.exe.
5.
(Optional) After the installation is complete, open the application and set any
application preferences that you want to be default for your users. For example, you
can set a default home page or custom security settings.
6.
After you have configured the application, exit the application.
7.
Right-click the capture icon in the system tray and choose Stop Capture.
8.
The layer is now listed in SVS Admin.
Testing Layers
After you have created a layer, you can test it to make sure it functions properly. To test
a layer, you can manually activate and use the layer on a computer. For more
information, see Testing, Activating, and Deactivating Layers (page 34).
Creating and Using Virtual Data Layers
Not only can you create virtual applications, but you can create virtual data layers. Using
data layers, you can capture data files and redirect them to a layer rather than having
them written to an application layer or the core file system. You can use one or more
data layers for each user.

Uses for Data Layers

How Data Layers Work
z
Creating Data Layers
Uses for Data Layers
Data layers can be useful in the following ways:
Storing data from virtual applications
Data layers can be useful in managing data generated from virtual applications.
Any data generated by a virtual application will, by default, be saved within the
Writeable sublayer of that application layer. This data will be lost if the layer is reset. By
using a data layer, the data is stored separately and will not be deleted due to a layer
reset. For general information about managing data with SVS, see Managing Data Within
Layers (page 50).
Providing a single, portable data store
Data layers can also be useful for having a single source of user data files that can easily
be exported to a VSA and moved or copied to a different computer. Example: You could
create a data layer to store a company’s product catalog and price list that is updated
monthly. Each month, this layer could be exported to a VSA and distributed to the sales
force to ensure they have the current files. The layer could then be deleted at the end of
each month to ensure that obsolete data is not circulated or available.
Software Virtualization Solution
42
How Data Layers Work
Using data layers, you can capture all files of a certain file extension and/or all files
saved to a specified directory.
Using file extensions
You can create a data layer that will capture all files with a specified extension.
Example: You have a layer for Microsoft Office. You can create a data layer and configure
that layer to capture all .DOC and .XLS file types. When a user saves a file from the
Office layer, all .DOC and .XLS files are stored into the data layer rather than the Office
layer. Those files are then protected if the Office layer is ever reset.
Files with the specified extension will be captured even if they are generated outside a
layer.
Using directories
You can also create a data layer for a specific directory. You can select whether or not to
include sub-directories. Example: You can create a data layer that captures all files
written to the My Documents folder. Any file saved to My Documents or one of it’s
subfolders would be redirected to the data layer.
New and existing files
When you create or deploy a data layer, there will usually be existing data files on the
computer with either the specified file extension or in the specified paths. Those files are
not automatically captured into the layer. Instead, as soon as the files are modified, they
are then redirected to the layer and removed from the core file system.
Creating Data Layers
To create a data layer
1.
On the base computer, open the SVS Admin tool.
2.
Select File > Create Layer.
3.
Click Data Layer and click Next.
4.
Name the layer.
5.
Select the capture method, file extension, or directory.
Note
When creating a data layer, you can configure either file extensions or a directory.
To use both, you must edit the layer after it is created. For information, see Viewing
and Editing Layer Properties (page 55).
„
To specify file extensions, do the following:
a. Select File extension(s).
b. Enter the file extensions.
Multiple extensions can be used by separating them with a semi-colon.
Example: doc;xls
Software Virtualization Solution
43
Do not include the wildcard asterisk, as it will be interpreted as part of the
file extension.
Example: do not use *.doc;*.xls
„
To specify a directory, do the following:
c. Select Directory.
d. Click Browse and select the directory.
By default, sub-directories will also be included. To not include
subdirectories, clear the Include subdirectories checkbox.
6.
Click Next.
7.
Click Finish.
The layer appears in SVS Admin.
8.
To activate the layer, right-click it and click Activate Layer.
Creating and Using Empty Layers
An empty layer has nothing captured into it. You can manually edit the empty layer later.
One useful purpose is creating an application layer for a program that does not have an
installer. You would create the empty layer and then use the Advanced Layer Editor to
add the files that are needed for the application.
To create an empty layer
1.
On the base computer, open the SVS Admin tool by clicking the SVS Admin icon on
the desktop.
2.
Select File > Create Layer.
3.
Choose Empty Layer and click Next.
4.
Name the layer and click Next.
5.
Click Finish.
For information on manually adding files to layers, see Viewing and Editing Layer
Properties (page 55).
Activating and Deactivating Layers
When a layer is created, it is activated by default. When a layer is activated, that means
that all the contents of the layer are visible. When a layer is deactivated, the contents of
the layer are hidden.
Activating and deactivating layers can be performed remotely or locally. Example: If you
are using Software Virtualization Solution in a Notification Server or Deployment
Solution environment, a helpdesk worker can remotely send a command to activate/
deactivate an application. If a computer is not connected to the network, a user can
manually activate/deactivate the layer.
For information about remotely activating and deactivating layers, see Using SVSCMD
Command-Line Parameters (page 61).
For information about manually activating and deactivating layers, see Testing,
Activating, and Deactivating Layers (page 34).

Deactivating Layers with Services Running
Deactivating Layers with Services Running
You cannot deactivate a layer while a process is running from that layer. If you try to
deactivate a layer with a process running, you will get a message stating that a process
is running and asks you if you want to stop the service. If you click Yes, the service will
be stopped and the layer will be deactivated.
The service PID (Process Identifier) is also displayed. You can use this PID to look up the
process in Task Manager. To see PIDs in Task Manager, it will need to be configured to
show the PID.
To see PIDs in Task Manager
1.
Open Windows Task Manager.
2.
Click the Processes tab.
3.
Select View > Select Columns.
4.
Select the PID (Process Identifier) checkbox.
5.
Click OK.
Resetting Layers
When a layer is created, the data captured is stored in a Read-only sublayer (see Layer
Architecture on page 19). If a user makes any changes to the application/data, that data
is stored in a Writeable sublayer. You can reset the layer, which deletes all the data
added by the user (writeable data) and maintains the original read-only data.
Resetting the layer is useful if an application becomes damaged. You can reset the layer
without having to uninstall/re-install the application. This is also useful in maintaining
standard versions and configurations of applications across your network.
Another advantage to resetting a layer is that is does not damage other applications
installed on the computer.
Using the Advanced Layer Editor, you can view files and settings that are contained in
the Read-only and Writeable sublayers. For information, see Viewing and Editing Layer
Properties (page 55).
Resets can be performed remotely or locally. Example: If you are using Software
Virtualization Solution in a Notification Server or Deployment Solution environment, a
helpdesk worker can remotely send a reset command to reset a damaged application. If
a computer is not connected to the network, a user can manually reset the layer.
To manually reset a layer

Software Virtualization Solution
In SVS Admin, do one of the following:
„
Highlight a layer and click File.
„
Right-click a layer.
Click Reset Layer.
45
For information about remotely resetting layers, see Using SVSCMD Command-Line
Parameters (page 61).
Caution
Any data generated by a virtual application will, by default, be saved within the
Writeable sublayer of that application layer. This data will be lost if the application layer
is reset. For general information about managing data with SVS, see Managing Data
Within Layers (page 50).
Updating Layers
You can update layers by modifying the contents of an existing layer. When you update a
layer, the capture mode is turned on, and any changes made on the computer are
captured. For example, you could open an application and change default settings.
When you update a layer using capture mode, the changes are made to the Read-only
sublayer making them permanent (see Layer Architecture on page 19).
Example: You may have a layer for Mozilla Firefox and you may want to change some
application preferences that you want to be default for your users.
You have the same capture options as when you created the layer—you can use either
Global capture or Single program capture.
z
Updating Layers Using Single Program Capture (page 46)
You can also use a command-line parameter to update a layer. For information, see
Using SVSCMD Command-Line Parameters (page 61).
Note
You cannot update a layer if any layers are active on the computer.
Updating Layers Using Single Program Capture
If you want to update a virtual application using Single program capture, there is
currently not a way to select the application process directly because the executable is in
the layer and the layer is not active.
Example: You may want to update a layer for Firefox by launching it using Single
program capture, letting it perform its auto updates, then automatically ending capture.
There is currently not a way to select the Firefox executable within an inactive layer.
However, there is a work-around available listed below.
To update a layer using Single program capture
1.
On the base computer, open the SVS Admin tool by clicking the SVS Admin icon on
the desktop.
2.
Select File > Update Existing Layer.
3.
Select the layer you want to update. Example: Firefox.
4.
Click Next.
5.
Select Single program capture.
6.

Deleting a layer deletes all data in the layer. Ensure that any files you want are moved
out of the layer before deleting it.
To delete a layer
1.
In SVS Admin, right-click the layer and click Delete Layer.
2.
Confirm that you want to delete the layer.
You can also use a command-line parameter to delete a layer. For information, see Using
SVSCMD Command-Line Parameters (page 61).
Exporting and Importing Layers
Layers can be exported to a Virtual Software Archive (VSA file) so that they can be
shared. VSA files can be stored on a network share, e-mailed, or deployed to client
computers on your network using Software Virtualization Solution or Deployment
Solution.
You can manually import an existing VSA using SVS Admin so that you can edit, update,
or use the layer as a stand-alone layer.

Data can be preserved or deleted depending on how layers are used.
This section includes the following topics:
z
Preserving Data (page 50)
z
Exclude Entries (page 51)
z
Deleting Data (page 54)
Preserving Data
When an application layer is active, all files created or modified by that layer, and that
are stored on the client computer, are redirected by the SVS File System Filter Driver to
the layer itself. (If files are stored on a network share, the SVS File System Filter Driver
does not redirect the file to the layer.) The files redirected to a layer are stored in the
Writeable sublayer. If a layer is reset, all data in the Writeable sublayer is deleted. In
many cases, you may want to preserve the files created from a layer. As a result, it is
important to properly manage the data within a layer so that data that should be
preserved is not deleted.
Example: If you have a Microsoft Word layer, and from that layer you save a DOC file to
the client computer’s hard drive, in any folder, that file will be redirected by the SVS File
System Filter Driver to the Microsoft Word layer. When the layer is active, the file will
appear to be stored in the destination folder that was selected, but the file is actually
stored in the SVS redirection area. If the Microsoft Word layer is reset, that DOC file will
be deleted.
Software Virtualization Solution
50
Non-local Storage
If you save a file from a layer to a non-local storage device, such as a network share,
the SVS File System Filter Driver will not redirect the file to the layer.There are three
ways to preserve data created through layers:
z
Exclude Entries (page 51)
z
Data Layers (page 53)
z
Non-local Storage (page 51)
Exclude Entries
Exclude entries are used to select file types and folders that you do not want to be
captured in layers.
Example: Suppose that you have a layer for Microsoft Word. You can exclude the file
types .DOC, .RTF, .TXT, .HTML, .XML, and so on, so that any data file that is saved by
the Word program in the layer is excluded from being redirected to the layer. Those files
will be saved in the core file system instead. You can also exclude directories so that any
files saved to a folder and its subfolders are not redirected.
There are two types of exclude entries:
z
Layer Exclude Entries (page 51)
z
Global Exclude Entries (page 52)
Layer Exclude Entries
You can configure a layer to exclude file types or folder locations so that specified file
types or files saved to a specified location will not be redirected by the SVS File System
Filter Driver into the layer. Instead it is saved directly to the core file system.
Layer exclude entries only apply to their associated layer, so you must configure the
exclude entries for each layer. For a more global solution, you can use Global Exclude
Entries (page 52) and Data Layers (page 53).
To configure layer exclude entries
Note
To configure exclude entries, the layer must be deactivated.
1.
Open SVS Admin.
2.
Double-click the deactivated layer.
3.
Click the Exclude Entries tab.
4.
Under Type, right-click and select New Exclude Entry.
5.
Select the entry type, file extension, or directory.
„
To specify file extensions, do the following:
e. Select File extension(s).
f.
Enter the file extension(s).
Example: doc
„
Software Virtualization Solution
To specify a directory, do the following:
51
g. Select Directory.
h. Click Browse and select the directory.
By default, sub-directories are not included. To include subdirectories, select
the Include subdirectories check box.
After an entry has been created, you can modify or delete it by right-clicking the entry
and clicking Modify or Delete.
Global Exclude Entries
You can setup exclude entries on a global level for a system. These entries can be file
type extensions or directory locations. Global Exclude entries are stored in the Windows
registry and apply to the system.
Example: You may want to always exclude all .DOC files or all files saved to the desktop,
regardless of which layer’s application created it.
During SVS installation you have the option to select two default directory locations to
exclude: My Documents and Desktop.
Global exclude entries only apply to application layer captures. Data layer specifications
always override global exclude entries. If you have a global exclude entry for My
Documents and you have also created a data layer that references files in My
Documents, then the data layer still functions correctly; the data layer still captures the
files.
Using SVS Admin or the SVS Control Panel Applet, you can add, modify, and remove
global exclude entries.
Editing Global Exclude Entries
1.
Open SVS Admin.
2.
Select Edit > Edit Global Excludes.
The Edit Global Exclude Entries window opens.

8.
Run this file on the computers where you want to copy the global exclude settings
to.
Caution
Running this file replaces the contents of the previous registry key with the new
contents.
Reloading the Global Exclude List
Whenever you change a global exclude entry, SVS Admin will automatically reload the
global exclude list. However, when you distribute global exclude entry settings to other
computers, using a .REG file as outlined above, you must manually reload the global
exclude list using SVS Command. The command line option is REL[OAD]. To do this:
1.
Click Start > Run.
2.
Enter CMD.
3.
Click OK.
4.
Enter SVSCMD.EXE.
5.
Enter SVSCMD REL.
The global exclude list is reloaded.
Data Layers
You can create a data layer that will capture data files into a dedicated data layer. This is
useful in storing data files that are created by other layers. Data layers cannot be reset
so the data files contained in data layers are protected.
For information, see Creating and Using Virtual Data Layers (page 42).
Software Virtualization Solution

Deleting Data
This topic describes what happens when you delete files when using layers.
There are two possible outcomes for deleting files while working with layers:
z
The file is not really deleted, but hidden while the layer is active.
z
The file is actually deleted.
These different results depend on how the layer is being used when a file is deleted and
also how the file was deleted.
z
When Files are not Deleted, but Hidden
z
When Files are Actually Deleted
When Files are not Deleted, but Hidden
When a layer is activated, under normal circumstance, files in the layer are visible that
are not visible when the layer deactivated. The opposite can also occur. Files in the core
file system may be deleted (hidden) when a layer is activated.
Example: During the capture process of installing Firefox, you create a shortcut for
Firefox and you also delete a shortcut for Internet Explorer. When the Firefox layer is
activated, the Firefox shortcut is visible while the Internet Explorer shortcut is not. When
the Firefox layer is deactivated, the Internet Explorer shortcut is again visible while the
Firefox shortcut is not.
Files that are deleted from the base from an application within a layer are not actually
deleted. They are hidden while the layer is active. When the layer is deactivated, the
“deleted” file is again visible.
The files or registry entries that are hidden are called delete entries and registry delete
entries. Delete entries and registry delete entries can be viewed through the Advanced
Layer Editor. For more information, see Viewing and Editing Layer Properties (page 55).
Delete entries can be stored in either the Read-only sublayer or the Writeable sublayer
depending on the way a layer is being used.
Delete Entries stored in the Read-only sublayer
When in capture mode, all changes made to the file system are stored in the layer’s
Read-only sublayer. If a file or registry setting was deleted while in capture mode, the
file is not actually deleted, but a delete entry is stored in the Read-only sublayer. This
would be the case in the Internet Explorer shortcut example listed above.
You can view and edit file delete entries and also registry delete entries from the Delete
Entries tab in the Edit Advanced Layer Properties window. See View Delete Entries
and Registry Delete Entries of a Layer (Application Layers Only) (page 61).
Delete Entries stored in the Writeable sublayer
When performing tasks through a virtual application all changes made are stored in the
Writeable sublayer. As a result, if you use a service in a virtual application to delete a file
in the Read-only sublayer, a delete entry is stored in the Read-only sublayer.
Example: You have a layer for Microsoft Word. From Word, you select File > Save As,
and a list of files is displayed in the current folder. You can delete an existing file from
the Save As dialog. If you delete a file that is in the Read-only sublayer, the file is not
Software Virtualization Solution
54
actually deleted, but a delete entry is stored in the Writeable sublayer and the file is
hidden.
This occurs because the file deletion was performed by a service running from the layer.
If the layer is reset, the delete entry is deleted and the deleted file would reappear from
the layer.
Another case of a delete entry being stored in a Writeable sublayer is when a file in the
Read-only sublayer is deleted by a process running outside of a layer. Example: If while
a Firefox layer is active, and using Windows Explorer, a Firefox program file in the Readonly sublayer is deleted, the file is not actually deleted, but hidden and a delete entry is
stored in the Writeable sublayer. The file will be restored if the layer is reset.
This illustrates one of the benefits of virtualized applications. If a virtualized application
becomes unusable because required files were deleted, the layer can be reset and all
original files are restored.
You can view and edit file delete entries and also registry delete entries from the Delete
Entries tab in the Edit Advanced Layer Properties window. See View Delete Entries
and Registry Delete Entries of a Layer (Application Layers Only) (page 61).
When Files are Actually Deleted
There are cases where files are actually deleted.
While a layer is active, if you delete a file in a layer’s Writeable sublayer, the file is
actually deleted from the layer. The files are deleted whether the deleting process is in
or out of a layer.
Since all files in a data layer are stored in a Writeable sublayer, deletions of files in a
data layer are permanent.
Note
In the case where a file is not really deleted but moved to the Recycle bin, the file is still
in the layer, under an folder node representing the recycle bin. The file is not actually
deleted until the recycle bin is emptied while the layer is active.
While a layer is active, if you delete a file that is not in a layer through a process that is
not in a layer, SVS is not involved and the file is deleted.
Viewing and Editing Layer Properties
Using SVS Admin, you can view and edit the contents of layers. In order to view or edit
layer properties, the layer must be deactivated.
To open the Advanced Layer Editor
1.
Open SVS Admin.
2.
Double-click a deactivated layer
This opens the Advanced Layer Editor.

View and Modify Files Contained in a Layer
In the Advanced Layer Editor under the Files tab, you can view all the folders and files
that are contained in the layer. The Read-only and Writeable sublayers are separated in
two different nodes (Read-only) and (Writeable). By default, the (Read-only) node is
displayed on top. You can either scroll down or collapse the (Read-only) node to see the
(Writeable) files.
The folder names that are displayed are the variablized names. For information about
variablization, see View Variables used in a Layer (page 57). To see what folders the
variablized folders represent, click the Variables tab.

Modifying Layer Files
Viewing Layer Files
To view the files in a layer, click a folder in the left pane and the files in the folder are
displayed in the right pane.
For example, you can view the following files in a Mozilla Firefox application layer.
To see the main program executable files, click layer name (Read-only) > System
> [Programfiles]. In this case, [PROGRAMFILES] represents C:\Program Files.
To see the Firefox bookmarks file that was captured with the layer, click
layer name (Read-only) > User-specific > USER_TEMPLATE > [APPDATA] >
Mozilla > Firefox > Profiles > xxx (where xxx is a Firefox controlled name. In this
case, [APPDATA] represents C:\Documents and Settings\username\Application Data.
If you have added a bookmark to the Firefox layer, the updated bookmarks file is written
to the Writeable sublayer and can be found under layer name (Writeable) > Userspecific > USER_SID > [APPDATA] > Mozilla > Firefox > Profiles > xxx.
If you reset a layer, you can see that all the files in the Writeable node are deleted.
Modifying Layer Files
In a layer, you can create new folders and copy, rename, and delete folders. You can
also copy, rename, and delete files. This is useful in modifying a layer without having to
recapture it.
Not only can you copy files within a layer, you can copy files and folders into a layer from
outside the layer and vice-versa. You can either use copy/paste or drag and drop.
Caution
Using the Advanced Layer Editor, you can’t overwrite files. To update a file, delete the
original and copy or move the new file.
Software Virtualization Solution
56
When using drag and drop, you can only move files into the layer, not copy. To copy, use
copy and paste, rather than drag and drop.
You can’t modify the actual file in a layer. Example: You can’t open and edit an .INI file.
You must activate the layer and then edit the file.
View and Edit Registry Settings Contained in a Layer
In the Advanced Layer Editor under the Registry tab, you can view or modify all the
registry settings that are contained in the layer. The Read-only and Writeable sublayers
are separated in two different nodes (Read-only) and (Writeable).
To edit registry settings you follow the same process as you would with Microsoft
Registry Editor. However, you must keep in mind that you have both the Read-only and
Writeable sublayers to maintain.
Note
SVS does not store data in the virtual HKEY_CLASSES_ROOT key. Instead it stores it in
its real location under either HKEY_USERS\USER_TEMPLATE\Software\Classes or
HKEY_LOCAL_MACHINE\Software\Classes. At runtime, Windows reads the SVS data for
active layers from these locations and properly renders HKEY_CLASSES_ROOT.
View Variables used in a Layer
Many applications have specific environment settings for file paths, paths in registry
values, .MSI paths, and so forth. To make VSPs portable across computers, many
application settings and data layer properties are variablized by Software Virtualization
Solution.
For instance, SVS uses common system variables to substitute for well-known locations
on a Microsoft Windows based installation, such as WINDIR as a substitute for the
“Windows” folder. This provides seamless compatibility with systems that may not be
using the standard folder structure, such as systems that have moved their “My
Documents” folder, or that have renamed operating system folders.
Example: If you have a VSP for My Documents, that may be on the C drive on one
computer but on a D drive on a different computer. Variablization allows the data layer
to work correctly on both computers.

they have in them.
To open the layer editor
1.
Open SVS Admin.
2.

3.
Click the Variables tab.
Variable Types
There are two types of variables: SYSTEM and USER.
System variables
System variables are static and loaded at boot time. Example:
WINDIR = C:\Windows
SYSTEMDRIVE = C:
User variables
User variables are per user and are loaded when the user logs
on. Example:
DESKTOP = C:\Documents and Settings\User\Desktop
USERPROFILE = C:\Documents and Settings\User
These are set as environment variables when layers are active
SVS uses the following tags to denote variables:
z
[_B_] = Beginning tag
z
[_E_] = Ending tag
z
[_CS_] = Convert to short path
z
[_MSI_] = Convert to .MSI path
When converting a path to its variablized form, the longest matching variablized path is
used. Example: C:\Documents and Settings\User\Desktop\1.txt would convert to
DESKTOP\1.txt not USERPROFILE\Desktop\1.txt

Configure Exclude Entries of a Layer
By default, data generated by a layer is stored in the layer. You can exclude data from
being saved in a layer so that it will be stored in the base file system. For information,
see Managing Data Within Layers (page 50).

View Delete Entries and Registry Delete Entries of a Layer
(Application Layers Only)
When using a layer, a user may delete a file or registry setting that is outside of the
layer. The file or registry setting is not actually deleted. It is hidden because if a file or
registry setting is from the Read-only sublayer, it needs to exist if the layer is reset.
Example: A user is using an application layer for Firefox and that user deletes a file. That
file is part of the Read-only sublayer and needs to be maintained. It is hidden from the
user but is displayed in the Delete Entries.
The Delete Entries tab in the Edit Advanced Layer Properties window, shows file delete
entries and also shows registry delete entries.
In the Delete Entries tab, you can view, select, and configure:
z
Read-only File Delete Entries
z
Writeable File Delete Entries
z
Read-only Registry Delete Entries
z
Writeable Registry Delete Entries.
Configure Data Capture Properties of a Layer (Data Layers
Only)
Data capture properties are configured in the same manner as exclude entries, except
for everything is referred to as a data capture item. The data capture properties dialogs
look and behave the same as the configuring exclude items dialogs.
Using SVSCMD Command-Line Parameters
When working with VSA files outside of the SVS Admin tool, you perform actions on VSA
files using the SVSCMD executable with command-line parameters. SVSCMD.exe is part
of the Software Virtualization Solution Agent installation. The following sections describe
how to use command-line parameters.
z
SVSCMD Usage Scenarios (page 61)
z
SVSCMD Parameters, Flags, and Examples (page 63)
SVSCMD Usage Scenarios
The section explains how SVSCMD is used in the following usage scenarios:
z
Notification Server Environment (page 61)
z
Deployment Solution Environment (page 62)
z
Stand-alone Environment (page 62)
Notification Server Environment
When Software Virtualization Solution is used in a Notification Server environment, the
Software Virtualization Agent (SVSCMSD) is deployed to managed computers. You
create a Virtual Software Package resource for each VSA file with the desired action and
Software Virtualization Solution
61
state. Each Virtual Software Package resource specifies the command-line to be used on
the VSA file.
Example: You may create a package that will activate a Mozilla Firefox VSA. In the
Virtual Software Package resource properties, you would specify the command-line
execution properties as:
SVSCMD.exe [LayerName|GUID] “Activate”
You also create a Virtual Software Task to deploy the package with the command-line
parameters to client computers. When the client computer receives the package, it runs
SVSCMD and activates the specified layer.
Note
The Virtual Software Wizard is provided to easily create packages and tasks with the
appropriate command-line statements. For information, see Using Software
Virtualization Solution in a Notification Server Environment (page 99).
Deployment Solution Environment
When Software Virtualization Solution is used in a Deployment Server environment, the
Software Virtualization Agent (SVSCMSD) is deployed to AClient-enabled computers.
You create a Deployment Server job for each VSA file with the desired action and state.
Each job specifies the command-line to be used on the VSA file.
Example: You may to deploy a Mozilla Firefox VSA and have it imported and
automatically activated. In the job, you would add a “Run Script” and specify the
command-line execution properties as:
SVSCMD.exe [LayerName|GUID] I -p [PathToExe] Auto -Y
For information about Deployment Server jobs, see Using Software Virtualization
Solution in a Deployment Solution Environment (page 151).
Stand-alone Environment
If you have the Software Virtualization Agent installed on a computer, but not the
SVSAdmin tool, you can use SVSCMD to perform layer tasks. Example: You can create
new layers or import existing VSA files. You can activate, deactivate, or reset layers.
Example: If you want to create a new layer for Mozilla Firefox, you would do the
following:
1.
Have access to the Firefox setup file.
2.
From the command-line, type:
SVSCMD.EXE “Firefox” CAPTURE -P “C:\FirefoxSetup1.0.7.exe”
Where “Firefox” is the name of the layer, CAPTURE tells SVSCMD to create a layer,
and -P “C:\FirefoxSetup1.0.7.exe” is the path to the setup file.
When the layer is created, it is activated automatically.
Layers are stored in a protected area on the file system and the files are not
viewable.

Using Layer Prioritization
There may be times when you need to control which layer has precedence in the event
that different layers have conflicting contents. Prioritization lets you control the priority
of those conflicting contents.
Example: If you open an HTML file, Windows Explorer will go to the registry and
determine which application is registered to open that file. When using Software
Virtualization Solution, you may have different application layers that are associated
with HTML files, such as Internet Explorer, Firefox, or Opera. You can control which layer
(which Web browser application) gets the priority and opens the file.
In another example, you may have different versions of the same .DLL file in different
layers. Prioritization lets you control which version of the .DLL file has the highest
priority and is therefore used.
Topics include:
z
How Prioritization Works on page 68
z
HKEY_CLASSES_ROOT Priorities on page 69
z
Configuring Layer Priorities on page 71
How Prioritization Works
When a request is made, Software Virtualization Agent does the following:
1.
Builds a list of all the active layers
2.
Assigns a priority to each active layers based on the following:
3.
„
The type of request that is being made (Normal or HKEY_CLASSES_ROOT)
„
Where is the request coming from
Orders and searches the layers based on priority
Request Types
Prioritization is based on two types of requests:
z
The request being made to the normal file system
z
The request being made to HKEY_CLASSES_ROOT
Software Virtualization Solution
68
Each type of request has a different set of priorities.
The following sections describe how to use prioritization:
z
HKEY_CLASSES_ROOT Priorities (page 69)
z
Configuring Layer Priorities (page 71)
HKEY_CLASSES_ROOT Priorities
This is the priority assigned to a layer when looking at HKEY_CLASSES_ROOT data.
HKEY_CLASSES_ROOT priorities are handled differently because this is typically what
applications use to register what files they use and they are not tied to the rest of the
layer priorities.
By using HKEY_CLASSES_ROOT priorities, you can control when an application registers
to handle certain extensions in HKEY_CLASSES_ROOT and you can order separately
than the file order of the application.
Example: Which application will be opened to handle a given file type.
For example, you may have two active layers for two different Web browser applications.
Both of them are registered to handle opened HTML files. You can use priorities to
determine which layer you want to open the HTML files.
Note
The HKEY_CLASSES_ROOT key is a virtual key that Windows creates by combining the
data from HKEY_CURRENT_USER\Software\Classes and
HKEY_LOCAL_MACHINE\Software\Classes. When there is a conflict in this data,
preference is given to the data contained in HKEY_CURRENT_USER\Software\Classes.
SVS does not store data in the virtual HKEY_CLASSES_ROOT key. Instead it stores it in
its real location under either HKEY_CURRENT_USER\Software\Classes or
HKEY_LOCAL_MACHINE\Software\Classes. At runtime, Windows reads the SVS data for
active layers from these locations and properly renders HKEY_CLASSES_ROOT.
z
Conflicting Settings within the Same HKEY_CLASSES_ROOT Priority
After the request is identified as a HKEY_CLASSES_ROOT type request, the priority is
based on where the location of the file or registry entry is located.
Software Virtualization Solution
69
HKEY_CLASSES_ROOT Priorities
Default
Priority
Location
Description
55.5 Highest
Owner Layer
If the executable that is used to start a process comes from a layer,
that layer is the “owner layer” for the process. Also, child processes
have the same “owner layer” as their parent process, regardless of
where their executable is located.
Example: Suppose you have an active layer for Firefox and you have
Internet Explorer installed in the base and both are registered in
HKEY_CLASSES_ROOT to be the default application for HTML files, then
when the Firefox layer is active, Firefox will be given priority and will be
used when an HTML file is opened.
65.5
Normal
Normal priority is given to HKEY_CLASSES_ROOT settings in any other
active layer than the application is not running from.
75.5
Base Owner
The base is the normal HKEY_CLASSES_ROOT settings on the
computer outside of any layers. If the process is running from the
base, the settings in the base are given this priority.
85.5 Lowest
Base
The base is the normal HKEY_CLASSES_ROOT settings on the
computer outside of any layers. If the process is not running from the
base, the settings in the base are given this priority.
Because there are no registry entries in a data layer, data layers are not considered for
HKEY_CLASSES_ROOT priorities.
HKEY_CLASSES_ROOT Priorities Example #1
You have an active layer for Firefox but also have Internet Explorer installed on the
base. If you open an HTML file, the Software Virtualization Agent will do the following:
1.
Build a list of all active layers and the base.
2.
Assign the following priorities:
3.
„
65.5 assigned to the Firefox layer that is the “owner layer”
„
85.5 assigned to the base
In this example, Firefox has the highest priority; therefore, it is launched.

HKEY_CLASSES_ROOT Priority
You may have a situation where you have conflicting settings within the same priority.
For example, what if you have two different active layers and each one is registered in
HKEY_CLASSES_ROOT to handle HTML files? You can set a different priority for each
layer.
For information on how to resolve priority conflicts, see Configuring Layer Priorities
(page 71).

Configuring Layer Priorities
You may have a situation where you have conflicting files within the same priority. For
example, what if you have two different active layers and each one is registered in
HKEY_CLASSES_ROOT to handle HTML files? You can set a different priority for each
layer.
Conflicting HKEY_CLASSES_ROOT Priorities Example #2
You have two active layers for different Web browsers: Firefox and Opera. If you open an
HTML file, it will do the following:
1.
Build a list of all active layers and the base.
2.
Assign the following priorities:
3.
„
65.5 assigned to the Firefox layer
„
65.5 assigned to the Opera layer
„
85.5 is assigned to the base
Determines which application to launch.
By default, because both Firefox and Opera have the same priority, it will not know
application to launch.
If you wanted to Firefox to always have priority of Opera, you can configure the
Firefox layer to be priority 65.3 and Opera would keep the default priority 65.5.
4.
In this example, because the Firefox label has the higher priority, Firefox will be
launched instead of Opera.
Note
If the two layers have the same priority, such as 65.5, then the priority is
undeterminable and which file or registry entry is used cannot be guaranteed.
To set layer priorities
You can set the priorities for a layer using command-line parameters with SVSCMD.EXE.
Note
Use caution when changing the priorities of layers. When setting a priority value, you
can specify any numeric value. However, we recommend that you only change the
values to the right of the decimal. If you change the values to the left of the decimal,
you will change the default priorities and may cause problems when new layer types are
created in the future. Example: If you have two layers that have a default priority of
65.5, you can change one to 65.3, giving it a higher priority than the other layer, but still
maintaining the general class of priority.
For general information about SVSCMD.EXE, see Using SVSCMD Command-Line
Parameters (page 61).
1.
On a computer where you have the agent installed, open a DOS window (Start >
Run > CMD > OK).
2.
From the DOS prompt, Type SVSCMD.EXE “LayerName” PRIORITY [-T|-L|-R]
-T[YPE] <type> = Priority type (HKCR).
-L[EVEL] <Level> = Priority of the layer.
Software Virtualization Solution
71
-R[ESET] = Resets the priority to default.
The following table list examples changing layer priorities.
SVSCMD.EXE “Sample App” PRIORITY -L 34.231
Sets the priority for the Sample App layer with a
priority value of 34.231.
SVSCMD.EXE “Sample App” PRIORITY -T HKCR -L 34.231
Sets the priority for the Sample App layer to type
HKCR with a priority value of 34.231.
SVSCMD.EXE “Sample App” PRIORITY -R
Resets the priority of the Sample App layer.
SVSCMD.EXE “Sample App” PRIORITY -T HKCR -R
Resets the priority of the Sample App layer and
sets the type to HKCR.
Managing Application Updates within Layers
A common use of Software Virtualization Solution is to have layers for application that
you commonly use. What if you want to update the application in a layer? For example,
suppose you have a layer for Microsoft Office, but an update or patch is released for
Office that you want to add to your Office layer.
It is possible to update the application within a layer; however, we recommend that
rather than updating an application layer that you create a new layer that contains both
the application and the update, and then remove the old layer and use the new one.
There are a couple of reasons for this:
z
If you update the application in a layer, the changes are captured into the Writeable
sublayer. If you ever reset the layer, those changes are deleted (see Layer
Architecture on page 19). So if you apply a security patch to a layer, but then later
reset the layer, the patch is deleted.
z
By patching individual layers, you lose the consistency of managing which users are
using which versions of applications. For example, if you run and .MSI repair on
different computers, different changes may be made and captured in the layer.
If you do want to update an application within a layer, do the following:
1.
Make sure that the .MSI for the application is in the layer (this will be the case by
default).
2.
In SVS Admin, select File > Update Existing Layer.
3.
Highlight the layer you want to update and click Next.
4.
Select Single program capture and click Next.
5.
Click Browse.
6.
Navigate to the setup file.
7.
Click Next.
8.
Click Finish.
This puts you in capture mode.
9.
Update the .MSI.
If this is a layer that you have deployed on your network, you will need to re-export it to
a .VSA file and redistribute it to client computers.

Handling Duplicate Services in Multiple Layers
You may have a situation where a service is run from the base or from a layer, and then
the same service is launched through a different layer. Software Virtualization Solution
uses reference counts to properly control the creation, starting, stopping, and deletion
of services with the Service Control Manager. If you deactivate the layer running a
service, the first instance of the service continues to run. The reference count
information is stored under HKLM\SYSTEM\Altiris\FSL\Services.

Installer Basics
The SVS Agent installer is a Windows Installer package and therefore includes many
features common to all Windows Installer packages. Some of the more common options
are documented in this section
The SVS Agent package installs a number of components on the system, some
optionally. The components installed and corresponding files are shown in the following
table. The paths shown are the defaults on a Windows XP English computer, so adjust
them appropriately for the systems you are working with.
Driver
C:\Windows\system32\drivers\fslx.sys
Library
C:\Windows\system32\fsllib32.dll
WMI Provider
C:\Program Files\Altiris\Software Virtualization
Agent\AltirisVSProvider.dll
C:\Program Files\Altiris\Software Virtualization
Agent\AltirisVSProvider.mof
Command-line Utility
C:\Program Files\Altiris\Software Virtualization
Agent\svscmd.exe
Graphical Admin Tool
C:\Program Files\Altiris\Software Virtualization
Agent\svsadmin.exe
C:\Program Files\Altiris\Software Virtualization
Agent\<Language>\svsadmin_resources.dll
C:\Program Files\Altiris\Software Virtualization
Agent\fslui.dll
C:\Program Files\Altiris\Software Virtualization
Agent\<LCID>\fslui_resources.dll
File Redirection Area
Software Virtualization Solution
C:\fslrdr
73
In addition to installing these files on the hard drive, the installer also creates the file
redirection area at C:\fslrdr. This is where files that are contained in virtual layers are
stored. There is a corresponding area of the registry where registry entries for the
virtual layers are stored. The installer creates this area at
HKEY_LOCAL_MACHINE\SYSTEM\Altiris\FLS in the registry. A few other registry keys
are created by the installer as described below.
Virtual Layer Metadata
HKEY_LOCAL_MACHINE\SYSTEM\Altiris\FSL
SVS Product Settings
HKEY_LOCAL_MACHINE\SYSTEM\Altiris\SVS
Registry Redirection Area
HKEY_LOCAL_MACHINE\SOFTWARE\fslrdr
After creating these resources, the installer has to register some of them on the system.
It installs the driver in a fashion similar to how a service is installed. (Do not expect to
see it in your services list, but the registry keys look very similar to a service.) The WMI
provider is installed using the programmatic equivalent of mofcomp.exe.
The installer sets the security permissions on the File Redirection Area and the Registry
Redirection Area. For these, administrators and the SYSTEM account are given full
access.
Finally, Windows Installer itself has some information that it stores about the
installation. It caches the installer package on the hard drive, creates an entry for the
agent in Add/Remove Programs, and stores some internal information about the
components installed.
After the installer has completed, it needs a restart in order for the product to become
fully usable.
Automating Installation
Now that you have an understanding of the installer package, what do you actually do
with it? An individual user may double-click the package and run the installer userinterface to perform the installation. The more advanced user or administrator may want
to use additional options discussed in this section to customize the installation and
automate it.
Rolling the agent out to an organization probably means doing a silent install. The
typical Windows Installer switches are a good start, but not sufficient. At a minimum you
will need to specify a product key in order to complete the installation. The following
command-line is an example of this:
msiexec.exe /qn /i Software_Virtualization_Agent.msi
PRODUCT_KEY=<product-key>
A few other command line parameters can be used to customize the installation, as
discussed in the following table.
Software Virtualization Solution
74
INSTALL_ADMIN=1
Installs the SVS Admin Tool.
Note: INSTALL_ADMIN=<any value> will cause
SVS Admin to be installed.
REBOOT=ReallySuppress
Suppresses restart prompts. Without this switch,
the installer will automatically restart the computer
(assuming that you are doing a silent install).
D_FSLRDR=D:\fslrdr
Changes the location of the file redirect area.
INSTALLDIR=C:\SVSAgent
Changes the install location of the command line
utility, WMI provider, and Admin tool.
PRODUCT_KEY=<product key>
Specifies the product key to be used to install. This
product key is obtained from Altiris, either when
you purchase the product or when you download a
key for free personal use of the product.
The following command silently installs the SVS Agent with SVS Admin:
msiexec.exe /qn /i “C:\Software_Virtualization_Agent.msi”
PRODUCT_KEY=<product-key> INSTALL_ADMIN=1
The following command installs the SVS Agent without SVS Admin (not silent):
msiexec.exe /qb /i “C:\Software_Virtualization_Agent.msi”
PRODUCT_KEY=<product-key>
Upgrades and Repairs
Upgrades and repairs of a broken installation can be accomplished through standard
Windows Installer methods. The product key is validated each time the install runs, and
therefore must be provided. The following commands repair an existing install and
upgrade the installation respectively.
msiexec.exe /qn /i Software_Virtualization_Agent.msi REINSTALL=All
REINSTALLMODE=omus PRODUCT_KEY=<product-key>
In this example, we use the Windows Installer product code for the SVS Agent rather
than pointing to an .MSI file. Since the installer has cached the .MSI file on the computer
during the initial install, the cached copy can be used for future repair work.
You can use a repair to install SVS Admin at some point after the initial install. This is
useful if you forget to include the parameter the first time the installer was run.
An upgrade looks almost identical, but provides a slight variation on the switches. In
order to do an upgrade, you need to provide a new .MSI file. You also need to tell
Windows Installer to recache the installer package using the new file (the v switch on
REINSTALLMODE does this).
msiexec.exe /qn /i Software_Virtualization_Agent.msi REINSTALL=All
REINSTALLMODE=vomus PRODUCT_KEY=<product-key>

Troubleshooting Failed Installs
Most failed installs can be successfully completed after a restart and reattempting the
install. In the event that this does not work, more drastic steps may be necessary.
In the event of an installation failure, you need to create a Windows Installer log in order
to determine where the failure occurs. You can add the /l*v <logfile> switch to the
command-line for the installation to generate a log file. Search for “return value 3”
inside the install log and the few lines above it should have an error message regarding
the failure.
This error message may tell you exactly what the problem is, such as an invalid product
key. In other cases, the error message indicates a more involved failure, such as not
being able to install the driver or WMI provider, or something similar. In those cases, you
may need to contact Altiris support or do a manual cleanup of the installation.
Manually cleaning up a computer is a simple matter of cleaning up everything the
installer does.
To clean up a computer
1.
Removing all the files and registry keys listed in the above sections.
2.
Delete the FSLX driver with the following command:
sc.exe delete FSLX
3.
Use the following command to remove the local group created for SVS Agent
security:
net.exe localgroup “Software Virtualization Administrators” /
delete
Removing the WMI Provider is a little more complex. Use the built-in tool named
wbemtest.exe for this purpose.
To remove the WMI Provider
1.
Launch wbemtest.exe.
2.
Click the Connect button.
3.
Enter the namespace “root\default” and click Connect.
4.
Click the Delete Class button
5.
Enter the class name “AltirisVSProv”, “VirtualSoftwarePackage”, and
“VirtualSoftwareSublayer” and follow the prompts to delete the class. For
Software Virtualization Solution
78
completeness, you also need to remove the registry keys created by the WMI
provider:
HKEY_CLASSES_ROOT\AppID\AltirisVSProvider.DLL
HKEY_CLASSES_ROOT\CLSID\{71D8DF9A-AD2D-44BF-A542-1412F68061D1}
HKEY_CLASSES_ROOT\TypeLib\{888967EF-E75C-4480-992D93FDA658F21E}
6.
Clean up the information that Windows Installer caches about the package. The
easiest way to do this is with a tool called msizap.exe from the Windows Installer
SDK. The following command removes all Windows Installer data for the SVS Agent:
msizap.exe TW! {7D8DBB7C-1C55-4950-A107-043C164F379A}
Uninstalling the Software Virtualization Agent
You can uninstall the Software Virtualization Solution Agent from client computers. By
default, uninstalling the SVS Agent does not remove layers. To uninstall the SVS Agent
and also remove all layers see Uninstalling the SVS Agent and removing all layers
(page 79).
Remotely uninstalling the SVS Agent
You can remotely uninstall the SVS agent by using one of the following command line
options:
z
Msiexec.exe /x Software_Virtualization_Agent.msi
or
z
Msiexec.exe /uninstall Software_Virtualization_Agent.msi
If you want to remotely uninstall the SVS Agent in a Notification Server environment,
see Uninstalling the Software Virtualization Agent with a Policy (page 143).
If you want to remotely uninstall SVS the SVS Agent in a Deployment Server
environment, see Using Deployment Server to Uninstall the Software Virtualization
Agent (page 155).
To manually uninstall the SVS Agent
To manually remove the Software Virtualization Agent from a computer, use the
Windows Control Panel > Add or Remove Programs Applet.
1.
Click Start > Control Panel > Add or Remove Programs.
2.
Select Altiris Software Virtualization Agent.
3.
Click Remove.
A dialog requests confirmation.
4.
Click Yes.
Uninstalling the SVS Agent and removing all layers
There is a command line switch that you can use to uninstall the SVS Agent along with
all local layers: DELETE_LAYERS=1
Example: Msiexec.exe /x Software_Virtualization_Agent.msi DELETE_LAYERS=1
Software Virtualization Solution
79
Manually removing layers after uninstalling the SVS Agent
If you have already removed the SVS Agent and you need to also remove layers, you
can:
z
z
Manually remove the layer files and registry keys
1.
Delete the FSLRDR directory. This is located by default at c:\fslrdr.
2.
Delete the HKEY_LOCAL_MACHINE\SYSTEM\ALTIRIS key, by running regedit,
browsing to the key, and selecting delete.
Reinstall the SVS Agent and then uninstall again passing in the DELETE_LAYERS=1
command line switch. For information see Uninstalling the SVS Agent and removing
all layers (page 79).
Software Virtualization Solution Security
Software Virtualization Solution uses the security systems that are built into the
Windows NT family of operating systems. Access to Software Virtualization Solution is
controlled by Access Control Lists (ACLs) in the registry and file system. The ability to
protect files and directories through ACLs requires the use of the NTFS file system. ACLs
on virtualized items (registry entries, files, and services) are persisted normally and
Software Virtualization Solution moves the ACLs when a Virtual Software Package (VSP)
is exported and imported. This section explains how SVS handles rights on virtual files,
and the on-disk structure of a VSP. It also explains how to make sure that anti-virus,
inventory, and other programs function correctly in the virtualized environment.
Rights necessary to administer Software Virtualization Solution
In order for a user to manipulate Software Virtualization Solution or VSP data through
SVS Admin, that user must be a member of the local Administrators group. There are
two exceptions: the rights to activate and deactivate can be delegated. Users that have
Read access to a key named HKLM\System\Altiris\FSL\Rights\Activate are able to
activate VSPs through SVSCMD or SVS Admin. Users that have Read access to a key
named HKLM\System\Altiris\FSL\Rights\Deactivate are able to deactivate VSPs through
SVSCMD or SVS Admin. Users that have rights to change the permissions on these keys
are able to modify these privileges for other users. While SVS Admin requires a user to
be an administrator in order to modify VSP data, the user may still be able to browse
directly into the Software Virtualization Solution redirection areas and modify files and
registry keys. The user will have the same rights to the files and registry keys in the
redirection areas as if the application had been installed normally, so this is not a
problem if the application properly creates ACLs for its files during install.
Anti-virus products and inventory products
Software Virtualization Solution does not affect the run-time protection feature of antivirus software. Anti-virus products properly scan virtualized files when they are opened.
Any measures that the anti-virus product takes against a file that it thinks is infected
really happen and are not virtualized. However, there is an issue with manual anti-virus
scanning. If multiple files exist in the base and in one or more VSPs and these overlay
each other, the scanner only sees and scans one of the files. For example, it might
enumerate a file named C:\TEST.TXT and scan it, but what it does not see is that a VSP
may have another version of the same named file. For this reason, we recommend that
anti-virus scanner programs be configured to be “ignored” by the SVS system. This
means that when the scanner programs run, they will not see any virtualized files; they
will only see the file system as it really exists. This guarantees that all files are properly
Software Virtualization Solution
80
scanned. The list of ignored executables can be modified by adding or removing strings
to HKLM\System\Altiris\FSL\ProgramIgnoreList which is a MULTI-SZ value. The paths
can be hard-coded (c:\windows\scan.exe) or variablized ([_B_]WINDIR[_E_]\scan.exe).
If you have other programs, like an inventory product, that you wish to have view the
file system data without any virtualization, you can add them to this list. You must
restart in order for these to be in affect.
VSP User Specific Areas
Data layers and the Writeable sublayer of Application layers are user specific. This
means that the layer has a unique area for each user that holds information that is
unique to each user. In the advanced editor in SVS Admin on the File tab, you can see
that these layers contain some areas that are common for all users, like the Windows
directory, but areas that are unique for each user exist under a SID directory. The
directory is named with a string representation of the user's SID. This directory contains
directories like the user's profile directory and desktop directory. A corresponding area
exists in the registry. Under HU (HKEY_USERS) you will see a SID directory for each
user. At runtime, this maps to HKEY_CURRENT_USER.
The Read-only sublayer of an Application layer does not contain unique entries for each
user. It contains only one copy of user data that is contained in a section called
USER_TEMPLATE. During the capture process, any user specific data goes into this area.
When the layer is first used by any user outside of capture mode, a SID directory is
created for the current user and the contents of the USER_TEMPLATE area are copied.
The USER_TEMPLATE area in the Read-only sublayer is not used during normal
operation.
Files, directories, and registry keys are protected with the same rights that protect the
corresponding objects in the base. Example: When the DESKTOP folder is created in the
layer, the ACLs are copied from the user's base DESKTOP folder. This assures that only
the proper users have rights to this folder.
The FAT file system is not secure. It does not support the protecting of files and
directories with rights. When you build layers that you plan to use on a computer that is
using an NTFS file system, you must build the layer on a computer that is using the
NTFS file system. If you build a layer on a computer that is using the FAT file system, no
rights will be used and when the layer is moved to a computer that is using the NTFS file
system, all files and directories will simply get default rights.
When a layer is exported, the rights that are contained in the file system are
represented in a file called “acls” in SDDL format. At import time, after the files and
directories have been extracted, this information is used to re-apply the proper rights.
Rights to services are handled in a similar fashion. An SDDL string is generated and used
to maintain the proper rights on the service.
Hiding the FSLRDR Redirect Locations
The SVS File System Filter driver has the ability to actively hide the fslrdr redirect
locations in the registry and the file system. These areas are already protected with
ACLs so that, by default, limited rights users are not able to enter these areas. Causing
the driver to actively hide these areas has the advantage that the locations are not
visible to anyone even if the system is configured to show hidden files. The disadvantage
of using this is that programs that traverse the entire file system looking for data
(Example: anti-virus scanners and inventory programs) will not see these areas either.
Software Virtualization Solution
81
Note
Enabling this does not affect run-time virus checking. To enable the active hiding of the
redirect locations by the driver, create a value called “HideRedirectAreas” of type
DWORD under HKLM\SYSTEM\Altiris\FSL. Set the value to “1”. A restart is required to
put into effect any changes to this value.
Launching of Startup Items
The information in this section does not apply when a layer is activated at start time
because it is marked to be active on start. This only applies when a layer is manually
activated.
When a layer is activated, Software Virtualization Solution typically launches all of the
items in the layer that are configured to run at startup. This includes entries in the
startup folder, the common startup folder, run entries, and run-once entries. The
launching of these programs happens in the context of the user that activates the layer.
This is a potential security concern. Example: When a layer is activated remotely by
Notification Server, this happens in the SYSTEM context by default. Because of this,
Software Virtualization Solution will not launch these items unless the activation is being
done by the interactive user who is logged on to the system.
This does not apply to the OnEvent actions. OnEvent actions are run regardless of how
the layer is activated. Care must be taken to ensure that actions configured to run in
these scenarios are secure and cannot be exploited by any users on the system.

Altiris SVS Applet
The Altiris® SVS applet is installed when you install the Altiris® Software Virtualization
Agent. It is available from the Control Panel and lets you create, import, export, and
manage SVS layers.
You can also use the SVS Admin to create, import, export, and manage SVS layers.

Creating a Layer with Altiris SVS Applet
You can use the Altiris SVS applet to create an application or data layer. When you place
applications and data into layers, you can instantly activate, deactivate or reset the
layers. By placing applications in a layer you completely avoid conflicts between
applications without altering the base Windows installation.
If you have Wise Package Studio® Professional Edition 7.0 or later or Wise Installation
Studio 7.0 or later installed, the applet uses Virtual Package Editor to create a layer.
Otherwise, the applet uses an SVS capture tool to create a layer.
Note
In runtime mode, the applet cannot create a layer.

Managing a Layer with Altiris SVS Applet
You can use the Altiris SVS applet to manage layers that you have created or imported
(see Creating a Layer with Altiris SVS Applet on page 83 or Importing a Layer with Altiris
SVS Applet on page 84). You can activate, deactivate, delete, export, rename, reset,
and make other changes to a layer. In runtime mode, some of the management
functionality is not available. ()
To manage a layer
1.
Select Start > Settings > Control Panel > Altiris SVS.
The Altiris SVS applet appears.
2.
On the Layers tab, you can do the following:
„
Delete, rename, or export a layer
To delete, rename, or export a layer, select the layer and use the buttons on the
right. For details on exporting, see Exporting a Layer with Altiris SVS Applet on
page 85.
„
Activate, deactivate, or reset a layer
To activate, deactivate, or reset a layer, select the appropriate option from the
layer’s right-click menu.
When a layer is activated, the layer name is displayed in bold type in the SVS
Altiris applet and all the contents of the layer are visible on the computer. When
a layer is deactivated, the contents of the layer are hidden. When a layer is
created, it is activated by default.
If you try to deactivate a layer that has a process running, you are prompted to
stop the process.
Resetting a layer is useful if an application becomes damaged. The layer can be
reset without having to uninstall or re-install the application. Another advantage
to resetting a layer is that is does not damage other applications that are
installed on the computer.
Note
You cannot reset data layers.
„

Creating and Editing Global Exclude Entries with
Altiris SVS Applet
Global exclude entries are used to specify certain file extensions or directories that you
want to exclude from all application layers. When any layer saves data with these
extensions or to these directories, the data is excluded from the layer and is not lost
when the layer is reset. (Example: You could create a global exclude for .DOC files. If
any layer creates .DOC files, the files are excluded from the layer. When the layer is
reset, the .DOC files are not lost.)
By default, predefined global exclude entries are created for the Desktop and the My
Documents directories. You can edit these predefined global exclude entries and create
your own.
Global exclude entries apply only to application layers. Specifications in data layers
override global exclude entries. (Example: If you have a global exclude entry for My
Documents and you have a data layer that requires files in My Documents, the files will
be saved in the data layer.)
To create and edit global exclude entries
1.
Select Start > Settings > Control Panel > Altiris SVS.
The Altiris SVS applet appears.
2.
Click the Options tab.
3.
To add an entry:

to take effect. This directory and registry key is displayed by default, but you might
want to hide it. If you are an administrator, use this option to protect layers from
malicious or accidental tampering. (Example: A user with rights might see the fslrdr
directory and, not knowing what it is, delete it. Then all layers would be lost.)
z

Configuration tab
From the Configuration Tab, you can install, upgrade, or install the Software
Virtualization Agent. You can also assign security privileges for software virtualization
administrative functions. For information, see Installing Software Virtualization Solution
(page 108).
Virtual Software Packages Overview
Virtual Software Packages are Notification Server resource objects that are used to
deploy virtual applications or virtual data layers to managed client computers. These are
similar to Software Delivery Packages that are used in Software Delivery Solution.
Virtual Software Packages contain Virtual Software Archive (VSA) files that are created
using the Software Virtualization Solution Admin (SVS Admin) tool. For information on
creating VSAs, see Getting Started with Virtual Software Layers and Archive Files
(page 31).
As part of the package definition process, you specify the locations from which an Altiris
Agent can download the package. By default, a package can be downloaded from the
location specified in the package as the source for the package. You can also specify
Package Servers where a package can be obtained. Package Servers let you reduce the
load on the Notification Server and the network by distributing packages to multiple
locations from which they can be downloaded. For more information on package servers,
see the Altiris Notification Server documentation.
The Altiris Agent stores package files on the same drive that the agent installed (in the
install path\Altiris\Altiris Agent\software virtualization\Package GUID folder). When
installing the Altiris Agent, install the Altiris Agent on a drive with sufficient space for all
the files that will be downloaded. If the Altiris Agent does not have sufficient disk space
Software Virtualization Solution
101
to download a package, a message is displayed by the Altiris Agent and a status
message is sent to the Notification Server. If the end user manually deletes the package
files, the Altiris Agent will re-download them from the Notification Server the next time
the Altiris Agent tries to run the package.
Virtual Software Package Actions and States
When a package is deployed to a client computer, there are different actions that you
can perform on it. Those actions control the two different states of a package: activated
and deactivated. The following table describes the possible actions and states:

Use this to delete Virtual Software Packages from the client computers.
For information on defining Virtual Software Packages, see Creating and Using
Notification Server Virtual Software Packages (page 116). For information on defining
Virtual Software Tasks, see Deploying Virtual Software Packages (page 124).
Package Download Overview
When a new package is defined, the package will be automatically downloaded to the
appropriate Altiris Agent Package Server the next time the Altiris Agent requests
configuration information from Notification Server. If you modify a package definition
within the Altiris Console, the changed files in the package will also be downloaded to
the appropriate Altiris Agent computers when the Altiris Agents check for configuration
information.
To send a package to a group of computers, the package must be assigned to a software
virtualization task, the destination computers must be a part of a collection assigned to
Software Virtualization Solution
103
the task, and the task must be enabled. For information, see Deploying Virtual Software
Packages (page 124).
If the actual files in a package change, Notification Server automatically recognizes the
changes. Notification Server checks for changed package files on a regular basis (once a
day by default). If Notification Server determines that files in a package have changed,
Notification Server will inform the appropriate Altiris Agents that the package has
changed. Only the changed files will be downloaded to the Altiris Agent again. The
interval that Notification Server checks for changed files can be modified (for
information, see Changing the Check for Updated Package Files Schedule on page 123).
The less frequently the check is made, the longer the time is required for a changed
package to be available on an Altiris Agent computer. The more frequently the check is
made, the more processing resources are required by Notification Server.
If the Software Virtualization Solution Agent cannot download a package due to a link
failure or denied access so a connection cannot be established, the Altiris Agent will
report a “Download failed - Link failure” status message. The Software Virtualization
Solution Agent will back off for N minutes (where N increases exponentially from a
default of 3 minutes to a default of 2 hours) before attempting to download the package
again.
If the Altiris Agent detects a network status change (a new network link), any package
waiting for a retry at being downloaded immediately restarts. The back off interval is
then reset to the initial value.
If a connection is lost during the download of a package, the transfer rate is throttled.
When the Altiris Agent attempts to download the package again, a buffer transfer delay
applies and slows down the download. The Altiris Agent determines which files in the
package still need to be downloaded and downloads those files.
If a source or destination fails during a package download, the checkpoint recovery
feature lets you continue the download of a package without starting over. Example: You
are deploying a package that is 20 MB in size and there is a network failure 15 MB into
the deployment process. When your systems are back up, the package deployment
resumes at the 15 MB point. The checkpoint recovery feature is always available; you do
not need to enable it.
Software Virtualization Solution Usage Overview
Using Software Virtualization Solution involves defining Virtual Software Layers and
Packages, creating Software Virtualization Tasks to deploy packages, and monitoring
feedback. The following steps outline the virtual software deployment procedure.
To deploy a Virtual Software Package
1.
Install Software Virtualization Solution on a Notification Server. See Installing
Software Virtualization Solution (page 108).
2.
Create Virtual Software Layers and Archive Files to include in Virtual Software
Packages. See Getting Started with Virtual Software Layers and Archive Files
(page 31).
3.
Rollout the Software Virtualization Agent to client computers. See Deploy the
Software Virtualization Agent (page 111).
4.
Use the Software Virtualization Wizard to do the following:
„
Software Virtualization Solution
Create a Virtual Software Package
104
„
Create a Software Virtualization Task to deploy the Virtual Software Package to
client computers
You can quickly create both packages and tasks using the Software Virtualization
Wizard. For information, see Create a new Virtual Software Package and Task
(page 111).
For information about manually creating packages and tasks, see Manually Creating
Virtual Software Packages (page 117) and Manually Creating a Virtual Software
Task (page 128).
Software Virtualization Solution Features
Software Virtualization Solution shares the following features with Software Delivery
Solution:
z
Bandwidth Throttling (page 105)
z
Blockout (page 105)
z
Multicasting (page 106)
z
Software Portal (page 107)
Bandwidth Throttling
Bandwidth throttling lets you control the amount of bandwidth used in the delivery of
packages. This feature can help minimize the impact of software deployment at peak
network usage times.
When the Software Delivery Agent (which is installed along with the Altiris Agent)
downloads a file, the agent downloads the file buffer by buffer with a delay between
each buffer. The buffer size and the amount of delay between buffers are both
configurable through the Altiris Agent. Different values can be used depending on the
bandwidth usage.
If bandwidth control is disabled by the user, the Software Delivery Agent will use no (0)
delay between buffers when downloading files. Effectively, the agent uses all of the
available bandwidth for package download.
If bandwidth control is enabled, the agent will test the data transfer rate by using full
bandwidth to download a package for 10 seconds, and then estimate the transfer rate
during that period of time. If the estimated transfer rate is less than a threshold, the
agent will then use a delay between buffer downloads to slow down the download
process. The data transfer rate test is done every two minutes to re-evaluate the link
speed during the package download. Therefore, bandwidth usage depends on the
transfer rate of the package download. For more information on the throttling feature,
see the Altiris Notification Server Reference.
Blockout
Blockout lets you block out times in which packages are delivered with a high priority,
low priority, or not at all. This feature lets you ensure that package delivery does not
take up significant network bandwidth during peak usage times. For more information
on the blockout feature, see the Altiris Notification Server Reference.
Software Virtualization Solution
105
Multicasting
Multicasting lets you transmit packages to a select group of recipients. This feature
improves Package Server performance on large networks for large customers using
significant amounts of network bandwidth. It protects Package Servers from being
overloaded and helps prevent slow network responses when distributing large packages.
Multicasting reduces the load on Package Servers by reducing the number of Altiris
Agents that connect to the Package Server and decreases network utilization by
multicasting package data to peers.
Sample Multicasting Scenario
A remote network segment consists of five Altiris Agents that remotely communicate to
the Notification Server.
When the first Altiris Agent updates its configuration, it is notified that there is a
package ready for download. If this Altiris Agent has multicasting enabled, it will begin a
multicast session and ask if any other Altiris Agents in the segment already have this
package. As other Altiris Agents in turn update their configuration and are also asked to
download this package they will join the multicast session to register that they too need
to download the package.
The Altiris Agents first negotiate to see who is going to be the 'master' of the session.
After the minimum numbers of Agents per multicast session join, one of two things will
occur:
z
If one of the Altiris Agents has the package, then it becomes the multicast master.
The master then waits for the minimum number of agents to join the session.
z
If no Altiris Agent in the session has the package, then they negotiate with each
other and pick a multicast master based on their respective OS, OS type, CPU
speed, and memory. This has a minimum timeout of 240 seconds. After the master
is chosen, it downloads the package in the usual manner and then waits for the
minimum number of agents to join the session.
The master Altiris Agent then multicasts the package over the physical subnet so that
each of the Altiris Agents in the multicast session can receive it.
If an Altiris Agent requests a package after it has been available for some time, it
attempts to join an existing session or else it begins a multicast session as normal.
This process optimizes the package download procedure. Only one Altiris Agent per
session will communicate with the Package Server or Notification Server to download the
package. Previously, each Altiris Agent required bandwidth and CPU usage to
communicate directly to the Package Server or the Notification Server. Multicasting
reduces this overhead by reducing significant amounts of network bandwidth usage and
thereby reducing load on the Package Server or the Notification Server.
Altiris Agents revert to unicast for downloading packages under the following
circumstances:
z
If the Maximum sessions per physical subnet value has been reached, the
backoff period initiates. If this occurs more times than the Maximum
transmission attempts per package, the Altiris Agent reverts to unicast.
z
If an Altiris Agent is connected to the session at less than 64 Kbytes/second, it is
removed from the session.
z
If the Maximum bandwidth used for multicasting has been reached.
Software Virtualization Solution
106
z
If the Maximum sessions per physical subnet value has been reached.
z
If the package is smaller than the Disable multicast for packages smaller than
value.
Package Servers and Multicasting
The following applies to Package Servers when multicasting:
z
Package Servers will always download a package using unicast.
z
If there is a Package Server on the subnet that has already downloaded a package,
it participates in the multicast session as the master.
Configuring Multicasting
You can select to use multicasting on the Advanced tab (Virtual Software Task Page)
(page 132). By default, all Software Delivery tasks that meet the criteria use
multicasting.
Caution
For a client computer to be included in a multicasting session, the Altiris Agent on that
computer must have multicasting enabled. Package multicasting is configured in the
Package Multicast tab on the Altiris Agent Settings page.
To enable multicasting

Verifying that a Policy Has Been Successfully Delivered to the Altiris Agent
Computer (page 134)
Virtual Software Task Overview
Virtual Software Tasks are policies that specify delivery and deployment information
about a Virtual Software Package. For a Virtual Software Package to be downloaded to
and deployed on the managed computer, there must be at least one Virtual Software
Task associated with that package. Each package can have more than one task
associated with it, but each Virtual Software Task is only associated with one package.
Virtual Software Tasks have several options on how they are run, depending upon how
they are configured. A Virtual Software Task can be run:
z
By the user of the managed computer through the Altiris Agent program or Software
Portal.
z
As soon as possible after the task has been requested by the Altiris Agent and the
run conditions are met. The run conditions are specified in the package definition
policy on the Programs tab. The condition options are Only when a user is
logged on, Only when no user is logged on, and Whether or not a user is
logged on.
z
According to a schedule specified in the Virtual Software Task.
Each Virtual Software Task has availability dates associated with it. These dates specify
when a task is first available and no longer available. The Virtual Software Package
associated with a task specifies the security context under which a program runs (local
system administrator or logged on user rights).
For information on creating a Virtual Software Task, see Manually Creating a Virtual
Software Task (page 128).
Virtual Software Task Priority
Each Virtual Software Task has an associated priority that is set in the definition of the
Virtual Software Task. The priority is used to set a priority when more than one Virtual
Software Task needs to download an associated package. The package associated with
the Virtual Software Task having the highest priority is downloaded first.
The Virtual Software Task will also be executed according to their priority order. Each
task will be executed to completion before another task is started.
Software Virtualization Solution
124
The priority options are Low, Normal, High, and Very High.
Virtual Software Task Status Files
The Software Virtualization Solution Agent keeps track of package download status
information for each package in a status file. The status is kept here: install
path\Altiris\Altiris Agent\software virtualization\Status\package guid\log.xml.
This file keeps track of the last 30 download attempts. This value can be adjusted by
editing the registry value “Download history size” located under the key
“HKLM\SOFTWARE\Altiris\Communications\Package Delivery” on the client computer.
The Software Virtualization Solution Agent keeps track of package execution status for
each task in the install path\Altiris\Altiris Agent\software
virtualization\AexSWDPolicy.xml file.
Disabled Virtual Software Tasks
If you disable a Virtual Software Task, or it is disabled due to platform mismatch,
expiration, filtering, or unavailability, the Software Virtualization Solution Agent will keep
that task’s status information for 10080 minutes (one week) by default, including any
downloaded packages. After one week, the associated status information is removed
entirely from the Altiris Agent computer. If the associated packages are no longer
referenced by any other active Virtual Software policies on the Altiris Agent, the
packages are also removed. (If you re-enable the policy after one week, any associated
software packages are downloaded again.) The one-week default can be changed by
modifying the software virtualization package and changing the package deletion option.
This cleanup process is performed once a day. For testing purposes, you can force a
cleanup within the next 5 minutes by removing the AdsStatusLastCleanUp registry value
under the following registry key:
HKLM\Software\Altiris\Altiris Agent\software virtualization
The following registry setting configures how long, in minutes, a Virtual Software Task
must be disabled before the status and packages are removed from the Altiris Agent
computer.
HKLM\Altiris\Altiris Agent\software virtualization\RemovedSoftPkgsCleanUpPeriod

Using Notification Policies and Automated Actions
Software Virtualization Solution supplies Notification Policies that provide active
reporting for the Altiris Agent.
Notification Policies automatically notify you when certain conditions exist. Notification
Policies can be set on something as simple as a single software virtualization failure or
specific set of conditions across multiple computers. Automated responses include
sending of e-mail, running corrective commands and scripts, generating SNMP traps,
and automatically generating a report and e-mailing you the URL of the report.
The automatic actions that can be taken by a Notification Policy are defined by
Automated Actions. Several Automated Actions can be associated with a single
Notification Policy. For more information on Automated Actions, see the Altiris
Notification Server documentation.

Using Deployment Server to Install the Software
Virtualization Agent
This procedure explains how to install the Software Virtualization Agent on client
computers managed by Deployment Solution.
Note
By default, the managed computer is restarted after the Software Virtualization Agent is
installed.
To install the Software Virtualization Agent using a job
1.
On your Deployment share, create a folder to store the agent and Virtual Software
Archive (VSA) files.
Example:
Create a folder named SVS with subfolders named Agent and VSAs, such as
\\servername\eXpress\SVS\Agent\
2.
Copy the Software_Virtualization_Agent.msi file into the folder that was just
created.
3.
Open the Deployment Console and create a new job. Example: Name the job,
“Install SVS Agent and Restart”.
4.
Add a “Distribute Software” task to the job.
5.
In the task, browse to the Software_Virtualization_Agent.msi file and select it as the
file to deploy.
6.
Select the “Run in quiet mode” checkbox.
7.
Under the Additional command-line switches add the following:
Software Virtualization Solution

PRODUCT_KEY=<product key>
For information about agent installation command line options, see Software
Virtualization Agent Installation (page 73).
8.
In the Code box, enter 1641.
To see the definition of this exit code open a command prompt and type “net
helpmsg 1641". It is a success code, but it is not recognized by DS as one.
9.
Click Finish.
10. After configuring the job, drag the job onto the managed computer and click OK.
Copying Virtual Software Archive Files to
Deployment Server
To deploy a Virtual Software Package (VSP), you must export the VSP to a Virtual
Software Archive (VSA). For information on creating VSAs, see Getting Started with
Virtual Software Layers and Archive Files (page 31). You must then make the VSA
available to the Deployment Server. The easiest way to do this is to copy the VSA files to
your Deployment Server.
To copy Virtual Software Archive files to Deployment Server
1.
We recommend creating a unique location on your Deployment share to store your
VSAs.
Example:
\\servername\eXpress\SVS\VSAs\
2.
Under the VSAs folder, create a subfolder for each VSA.
Example:
\\servername\eXpress\SVS\VSAs\AcrobatReader7
\\servername\eXpress\SVS\VSAs\Firefox 1.5
3.
Copy the VSA files to the appropriate folders on your Deployment share.
Using Deployment Server to Deploy VSPs
This procedure explains how to create a job in Deployment Server to import a VSA and
set it to activate on start.
To deploy a VSP using a job
1.
From the Deployment Console, create a new job. Example: Acrobat Reader 7.
2.
Under the job folder, create a new Copy file task.
Example: Acrobat Reader 7: Import and Set Activate on Start.
3.
Enter the source path where the VSA is stored on the share.
4.
Enter a destination path for the VSA to be copied on the managed computer.
Example: C:\windows\temp.
5.
Click Finish.
Software Virtualization Solution
153
6.
Create a new Run Script task inside of the job to call the SVS command-line
interface.
Example:
SVSCMD.exe I -P “C:\windows\temp\AcrobatReader7.vsa”
SVSCMD.exe “AcrobatReader7” AUTO -Y
For a list of available command-line options and information on how to use them,
see Using SVSCMD Command-Line Parameters (page 61).
7.
Select Windows as the script operating system.
8.
Click Next.
9.
Click Finish.
10. Drag and drop the computer on the job.
11. In many cases, depending on the application, after the job has completed, the
managed computer may need to be restarted. You can do this using Deployment
Server power controls.
Using Deployment Server to Manage VSPs
You can also use jobs to manage VSPs, such as resetting, deactivating, and deleting.
To manage VSAs using a job
1.
Create a new job. Example: Acrobat Reader 7: Reset.
2.
Create a new Run Script task inside of the job to call the SVS command-line
interface.
Example: To reset the VSP, use the following script:
SVSCMD.exe “AcrobatReader7” RESET -F
You can use a wide variety of command-line options. For a list of available
command-line options and information on how to use them, see Using SVSCMD
Command-Line Parameters (page 61).
3.
Select Windows as the script operating system.
4.
Click Next.
5.
In the Script Window option, select Hidden.
6.
Click Finish.
7.
Drag and drop the client computer onto the job.

Using Deployment Server to Uninstall the Software
Virtualization Agent
This procedure describes how to uninstall the Software Virtualization Agent from a
managed computer using Deployment Server.
Note
By default, uninstalling the Software Virtualization Agent does not remove layers. To
uninstall the Software Virtualization Agent and also remove all layers see Uninstalling
the SVS Agent and removing all layers (page 79)
To uninstall the Software Virtualization Agent using a job
1.
Under the job, create a new Copy file task.
Example: Uninstall SVS Agent and Restart.
2.
Enter the source path where the VSA is stored on the share.
3.
Enter a destination path for the file to be copied on the managed computer.
Example: C:\windows\temp.
4.
Click Finish.
5.
Add a run script task to the job to execute the following script:
Msiexec.exe /x c:\windows\temp\Software_Virtualization_Agent.msi /q
6.
Select Windows as the script operating system.
7.
Click Next.
8.
In the Script Window option, select Hidden.
9.
Click Next.
10. At the Return Codes screen, click Add.
11. In the Code box, enter 1641.
To see the definition of this exit code open a command prompt and type “net
helpmsg 1641". It is a success code, but it is not recognized by Deployment Server
as one.
12. Change the Response to Continue and Result to Success.
13. In the Status box, enter “SVS Agent removed, machine restarting”.
14. Clear the “Add to Master return code list” checkbox.
15. Click OK.
16. Click Finish.
17. Drag the computer to the job.
