I coped 32bit image from CentOS 5 i686 to new CentOS x86_64 5.1 2.6.18-53.1.14.el5xen host server. Under load I see kernel exceptions in log file and some times guest system crashed. I attached piece of guest log between crashes. If anybody could help me to solve the crashes, I would very much appreciate it.
