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 -- Tim Verhoeven - tim.verhoeven.be at gmail.com - 0479 / 88 11 83 Hoping the problem magically goes away by ignoring it is the "microsoft approach to programming" and should never be allowed.
