5. Troubleshooting with the Logs
When encountering issues with installing Red Hat Virtualization, you can refer to the host
system's two logs to assist with troubleshooting. The xend.log file contains the same basic
information as when you run the xm log command. It resides in the /var/log/ directory. Here
is an example log entry for when you create a domain running a kernel:
[2006-12-27 02:23:02 xend] ERROR (SrvBase: 163) op=create: Error creating
domain: (0, 'Error')
Traceback (most recent call list)
File "/usr/lib/python2.4/site-packages/xen/xend/server/SrvBase.py" line 107
in_perform val = op_method (op,req)

raise XendError ("Error creating domain: " + str(ex))
