Just checking, since you didn't specify. The Xen version is the one
included in Centos 5.5 and the packages are up to date?

How do you characterize this, what metrics are you using?

What console?

Nothing is running on the VM?

Can you post some log files? For example, the xend log. dmesg in the
guest, xm dmesg, etc. anything that could give some more information.

How? What operations caused this and how did you determine corruption?

Providing more information to the list allows us to give better suggestions.

For example, have you tried over types of guests? Linux, PV, etc.?
Similar problems?

Also, you may find hints by searching xen.markmail.org for similar issues.

Hope that helps.

Thanks,
Todd
