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)

File

"/usr/lib/python2.4/site-packages/xen/xend/server/SrvDomainDir.py line 71 in

op_create

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

XendError: Error creating domain: (0, 'Error')
