I have a server with CentOS 5.8.Final, running the 2.6.18-308.4.1.el5xen kernel. I installed the Virtualizorpanel 2 months ago and my VPS are OK, but yesterday one of my VPS crashed. I changed theRAM when it was in suspended status, and after that I got this error at _/var/log/xen_

[2012-08-24 20:03:48 xend.XendDomainInfo 3846] DEBUG (XendDomainInfo:2191) _initDomain:shadow_memory=0x0, maxmem=0xa00, memory=0xa00.

When i try to mount VPS LVM at /dev/VolGroup01/vs1008, I can't see the filesystem. Only some files! I really need filesystem.

A log of the VPS start is below.

Tried fsck on the filesystem? –  Andrew Smith Aug 25 '12 at 15:50
    
Patch your system. Current Kernel is -308.13 - since -308.4 there have been xen-patches as well (and numerous other patches, including glibc). –  Nils Sep 1 '12 at 21:03
