Hi, I'm moving this thread to the CentOS-virt mailinglist (please
remove the centos mailinglist to everyone replying to this mail) since
it is more suited for these kind of questions.

Question, If I read those crashes correctly your 4.6 domU is a 32 bit
one ? What platform is your dom0 32 or 64 bit? Running a 32 bit domU
on a 64 bit dom0 is currently not really stable. This is suppose to
improve with 5.2

Regards,
Tim

Hoping the problem magically goes away by ignoring it is the
"microsoft approach to programming" and should never be allowed.
