XenCenter has a simple and intuitive UI. However when problems happen, the log tab sometimes doesn’t contain enough information to help with debugging the issues.  I found it very useful to take a look at the debug log in %appdata%\Citrix\XenCenter\logs\XenCenter.log.  For example, the log file may be in C:\Documents and Settings\<user name>\Application Data\Citrix\XenCenter\logs directory. Please note that Application Data directory may be hidden.

Here is an example of what’s contained in the log:
