So here is an issue. I had a server running 30 vm.
Yesterday for some reason it went down with no indication of any error.
After powercycle all VMs were in mounted state and would not boot. Only 2-3 procs woud show up when I did vzctl start VE.
NO kernel upgrade was performed at reboot. Same kernel that was running before reboot.
At the same moment simple w command started to show unreal numbers 30 seconds after reboot:
JCPU 416days
PCPU 208days

10 minutes later
JCPU 6879days
PCPU 0.00

At this point I have transferred all VMs out of there and started to play with latest vz kernels. Server at the moment was running Centos 6. Server with the same absolut specs is sitting next to it and running 60 vms on Debian 6.
So i have decided to reinstall clean into debian 6 since bugs were following me on all kernels i have tried.
Debian 6 it was. Reinstalled. When i booted initially, not problems and JPCU and PCPU in Debian. I installed openvz kernel from debian repo. It's an old one 2.6.32-5-openvz-amd64. But running it there are no problems, but it does not have ipv6 and vswap, so no go.

I have even tried to install proxmox kernel and still the same issue.

Bellow you can see kernels i have tried. VMs just would not boot with these kernels.
I have tried 59, 75, 76 - tables, 78 - 78.22 testing kernels. No luck.

Can someone please assist me or give directions to how to deal with this issue?
