Getting Started with ESX Get started with ESX quickly with this information about installation and initial setup. Follow the procedures included here to install and set up a basic inventory for a single-host virtualization environment. After your host is set up with a working virtual machine, you can install vCenter Server and explore a multiple-host virtualization environment. This information is for experienced Windows or Linux system administrators who will be installing VMware ESX to deploy virtualization for the first time. Specifically, it is for users who meet the following requirements: n Do not yet have the ESX software installed n Do not yet have the vSphere Client or VMware vCenter Server installed. Getting Started Tasks The getting started tasks take you from initial setup of a new virtualization host to a working virtual machine. After you have a host and functional virtual machine, you can set up a managed host environment with vCenter Server. Getting started with ESX includes the following tasks: n Installing ESX and adding the host to your network n Installing the vSphere Client and connecting to the ESX host n Deploying and running a virtual machine Completing the getting started tasks sets up the single-host management system for virtualization as shown in Figure 1. Figure 1. Basic Single-Host Management System After the initial setup of ESX, you can deploy vSphere 4.0 with vCenter Server to manage multiple hosts. VMware, Inc. 7 Getting Started with ESX ESX Installation Install ESX to get started with running virtual machines. The machine running ESX virtualization software acts as a host in your virtual infrastructure. Hosts provide CPU and memory resources, access to storage, and network connectivity for the virtual machines that reside on them. Prerequisites for Installing ESX Before you begin the installation procedure, ensure that the host meets the prerequisites. The prerequisites are as follows: n If ESX will not use an NTP server, make sure that the server hardware clock is set to UTC. This setting is in the system BIOS. n Make sure the host has a supported network adapter. ESX Hardware Requirements Using ESX requires specific hardware and system resources. 64-Bit Processor n VMware ESX 4.0 will only install and run on servers with 64-bit x86 CPUs. n Known 64-bit processors: n All AMD Opterons support 64 bit. n All Intel Xeon 3000/3200, 3100/3300, 5100/5300, 5200/5400, 7100/7300, and 7200/7400 support 64 bit. n All Intel Nehalem (no Xeon brand number assigned yet) support 64 bit.

What to do next After you complete the installation, use the vSphere Client to connect to the ESX host. Managing Your First ESX Host You manage hosts using the vSphere Client. After you finish initial setup of the host, download and install the vSphere Client. Connect to the host and add your first virtual machine by importing a virtual appliance. vSphere Client Hardware Requirements Make sure that the vSphere Client hardware meets the requirements. n CPU – 1 CPU n Processor – 266MHz or faster Intel or AMD processor (500MHz recommended). n Memory – 200MB RAM n Disk Storage – 1GB free disk space for a complete installation, which includes the following components: VMware, Inc. n Microsoft .NET 2.0 n Microsoft .NET 3.0 SP1 n Microsoft Visual J# n vSphere Client 4.0 n vSphere Host Update Utility 4.0 11 Getting Started with ESX You must also have 400MB free on the drive that has your %temp% directory. If all of the prerequisites are already installed, 300MB of free space is required on the drive that has your %temp% directory, and 450MB is required for the vSphere Client 4.0. n Networking – Gigabit connection recommended. vSphere Client Software Requirements Make sure that your operating system supports the vSphere Client. The vSphere Client requires the Microsoft .NET 3.0 SP1 Framework. If your system does not have it installed, the vSphere Client installer installs it. For a list of supported operating systems, see the vSphere Compatibility Matrixes at http://www.vmware.com/pdf/vsphere4/r40/vsp_compatibility_matrix.pdf on the VMware vSphere documentation Web site. Download the vSphere Client The vSphere Client is a Windows program that you can use to configure the host and to operate its virtual machines. You can download vSphere Client from any host. Prerequisites You must have the URL of the host. This is the IP address or host name. Procedure 1 From a Windows machine, open a Web browser. 2 Enter the URL for the host. For example, http://testserver.vmware.com or http://10.20.80.176. The welcome page appears. 3 Click Download the vSphere Client under Getting Started. 4 Click Yes in the security warning dialog box that appears. What to do next Install the vSphere Client. Install the vSphere Client The vSphere Client enables you to connect to an ESX/ESXi host and to a vCenter Server system. The vSphere Client must be installed on a Windows machine that has network access to the ESX host and Internet access. Procedure 1 12 Run the vSphere Client installer. n In the vCenter Server installer, double-click the autorun.exe file at C:\<vc-installer location>\ and click VMware vSphere Client. n If you downloaded the vSphere Client, double-click the VMware-viclient.exe file. 2 Choose a language for the installer and click OK. 3 When the Welcome screen appears, click Next. 4 Select I agree to the terms in the license agreement and click Next.

Procedure 1 Start the vSphere Client. Double-click a shortcut or select Start > Programs > VMware > VMware vSphere Client. 2 Log in to the ESX host as the administrator. a Enter the IP address or host name you noted earlier. b Enter the username root. c Enter the password you specified using the direct console. If you did not set the password using the direct console, leave the Password field empty. 3 Click Login. A security warning appears. 4 To continue, click Ignore. This security warning message occurs because the vSphere Client detected a certificate that the ESX host signed (default setting). For highly secure environments, VMware recommends certificates that a trusted third party generates. You can set up third-party certificates later. VMware, Inc. 13 Getting Started with ESX What to do next After you connect to the host with the vSphere Client, use the Getting Started tabs to import a virtual appliance. Add Your First Virtual Machine by Importing a Virtual Appliance After you connect to the host machine, you can add a virtual machine to the host. You can import or create one or more virtual machines on a single host. To add virtual machines to hosts, you can build a new virtual machine or import a virtual appliance from the VMware Web site. A virtual appliance is a prebuilt virtual machine with an operating system and applications already installed. The vSphere Client Getting Started tab provides steps to guide you through both options. If this is your first virtual machine, VMware recommends that you import a virtual appliance. Figure 2. Getting Started Tab for a Host Procedure 1 14 In the Getting Started tab, click Import a virtual appliance. VMware, Inc. Getting Started with ESX 2 Select VA Marketplace and click Next. 3 Select a virtual appliance from the list and click Download now. For the shortest download time, VMware recommends that you chose a small virtual appliance. 4 Click Next and follow the on-screen instructions to import the virtual appliance. After you import the virtual appliance, you can use the Console tab in the vSphere Client to power it on and view it. To release the pointer from the Console, press Ctrl+Alt. To view the Console in full screen mode, from the Inventory, right-click the virtual machine and select Open Console. What to do next You have completed setup for a single-host management system in which ESX is used to run virtual machines. Explore the advantages of managing multiple hosts with vCenter Server. Managing Multiple Hosts with vCenter Server You can deploy VMware vSphere with vCenter Server to manage multiple hosts at the same time. Using vCenter Server to manage multiple hosts allows you to experiment with advanced management options, such as resource sharing, and all of the other options available within the vSphere environment. Deploying vCenter Server provides many advantages over deploying a single, standalone ESX host. Table 1 illustrates some of the advantages and compares multiple-host management with vCenter Server as opposed to single-host management. Table 1.

It accomplishes this by managing the assignment of virtual machines to the hosts and the assignment of resources to the virtual machines within a given host based on the policies that the system administrator sets. vCenter Server allows the use of advanced vSphere features such as VMware Distributed Resource Scheduler (DRS), VMware High Availability (HA), and VMware VMotion. Datacenter A datacenter is a structure under which you add hosts and their associated virtual machines to the inventory. Virtual Machine A virtual machine is a software computer that, like a physical computer, runs an operating system and applications. Multiple virtual machines can run on the same host at the same time. Virtual machines that vCenter Server manages can also run on a cluster of hosts. Figure 3 shows the relationships among the basic components of vSphere and how vCenter Server can be used to manage hosts and run virtual machines. 16 VMware, Inc. Getting Started with ESX Figure 3. vSphere Components vCenter Server Installation Install vCenter Server to manage multiple hosts. To get started with vCenter Server quickly and manage the host you set up, you can installed vCenter Server on a desktop or laptop. You must install vCenter Server on a Windows machine that has network access to the ESX host. For production use, VMware recommends that you install vCenter Server on a dedicated server system. Before you install vCenter Server, make sure your system meets the minimum hardware and software requirements. vCenter Server requires a database. vCenter Server uses Microsoft SQL Server 2005 Express for small deployments with up to 5 hosts and 50 virtual machines. For larger deployments, VMware supports several Oracle and Microsoft SQL Server databases. Refer to the vSphere Compatibility Matrixes for the list of supported databases. vCenter Server and the vSphere Client Hardware Requirements The vCenter Server system is a physical machine or virtual machine with access to a supported database. The vCenter Server system and the vSphere Client machines must meet specific requirements. Minimum Requirements for vCenter Server n CPU – 2 CPUs n Processor – 2.0GHz or faster Intel or AMD processor. Processor requirements might be higher if the database runs on the same machine. n Memory – 3GB RAM. Memory requirements might be higher if the database runs on the same machine. vCenter Server includes a service called VMware VirtualCenter Management Webservices. This service requires 128MB to 1.5GB of additional memory. The VirtualCenter Management Webservices process allocates the required memory at startup. n VMware, Inc. Disk storage – 2GB. Disk requirements might be higher if the database runs on the same machine. 17 Getting Started with ESX n Microsoft SQL Server 2005 Express disk requirements – Up to 2GB free disk space to decompress the installation archive. Approximately 1.5GB of these files are deleted after the installation is complete. n Networking – Gigabit connection recommended. See your database documentation for the hardware requirements of your database. The database requirements are in addition to the vCenter Server requirements if the database and vCenter Server run on the same machine. vCenter Server Software Requirements Make sure that your operating system supports vCenter Server. For a list of supported operating systems, see the vSphere Compatibility Matrixes at http://www.vmware.com/pdf/vsphere4/r40/vsp_compatibility_matrix.pdf on the VMware vSphere documentation Web site. vCenter Server Prerequisites Before installing vCenter Server, review the prerequisites. n You must have the installation DVD or download the installation ISO image. n Your hardware must meet the vCenter Server hardware requirements. n If the machine on which you are installing vCenter Server has VirtualCenter installed, you might want to upgrade instead of performing a fresh installation of vCenter Server. IMPORTANT If you want to keep your existing VirtualCenter configuration, see the Upgrade Guide. n There must be no Network Address Translation (NAT) between the vCenter Server system and the hosts it will manage. n For the installation of vCenter Server, VMware recommends installing the bundled SQL Server 2005 Express database on one of the supported operating systems. If SQL Native Client is already installed, uninstall SQL Native Client before you begin the vCenter Server installation. n The system that you use for your vCenter Server installation will belong to a domain rather than a workgroup. If assigned to a workgroup, the vCenter Server system is not able to discover all domains and systems available on the network when using such features as vCenter Guided Consolidation Service. To use vCenter Linked Mode, multiple vCenter Server systems should be added to a domain. To determine whether the system belongs to a workgroup or a domain, right-click My Computer and click Properties and the Computer Name tab. The Computer Name tab displays either a Workgroup label or a Domain label. n During the installation, the connection between the machine and the domain controller must be working. n The computer name cannot be more than 15 characters. n The DNS name of the machine must match the actual computer name. n Make sure the system on which you are installing vCenter Server is not an Active Directory domain controller. n On each system that is running vCenter Server, make sure that the domain user account has the following permissions: n 18 n Member of the Administrators group n Act as part of the operating system n Log on as a service Assign a static IP address and host name to the Windows server that will host the vCenter Server system. This IP address must have a valid (internal) domain name system (DNS) registration that resolves properly from all managed ESX hosts. VMware, Inc. Getting Started with ESX n If you install vCenter Server on Windows Server 2003 SP1, the disk for the installation directory must have the NTFS format, not the FAT32 format. n vCenter Server, like any other network server, should be installed on a machine with a fixed IP address and well-known DNS name, so that clients can reliably access the service. If you use DHCP instead of a static IP address for vCenter Server, make sure that the vCenter Server computer name is updated in the domain name service (DNS). One way to test this is by pinging the computer name. For example, if the computer name is host-1.company.com, run the following command in the Windows command prompt: ping host-1.company.com If you can ping the computer name, the name is updated in DNS. Install vCenter Server vCenter Server allows you to centrally manage hosts from either a physical or virtual Windows machine, and enables the use of advanced features such as VMware Distributed Resource Scheduler (DRS), VMware High Availability (HA), and VMware VMotion. Prerequisites See “vCenter Server Prerequisites,” on page 18. Procedure 1 In the software installer directory, double-click the autorun.exe file at C:\<installer location>\. 2 Click vCenter Server. 3 Choose a language for the installer and click OK. 4 When the Welcome screen appears, click Next. 5 Select I agree to the terms in the license agreement and click Next. 6 Type your user name, organization, and vCenter Server license key, and click Next. If you omit the license key, vCenter Server will be in evaluation mode, which allows you to use the full feature set. After installation, you can convert vCenter Server to licensed mode by entering the license key using the vSphere Client. VMware, Inc. 19 Getting Started with ESX 7 Click Install SQL Server 2005 Express instance (for small-scale deployments). This database is suitable for small deployments of up to 5 hosts and 50 virtual machines. 8 Enter the administrator name and password that you use when you log in to the system on which you are installing vCenter Server and click Next. You need the user name and password entered here to log in to vCenter Server after you have installed it. 9 20 Select Use SYSTEM Account and click Next. VMware, Inc.
