Hello guys,
Im running into issues with running VM's(ubuntu server).
Sometimes this happens at the beginning when I start to install OS, sometimes when I run 2 VMs .. completely randomly.

Any help is appreciated.

Thanks!
 
Hi again,
did memory check - everything looks good.
Ive reinstalled proxmox.
the same issue :(

any ideas where might be the issue.
thanks in advance.
please let me know if I need to provide more specific info.

Have you tried other OSes as well or does the issue specifically appear on Ubuntu?

have you more details about your CPU (Stepping Code etc.)?
I do recall we had some very very strange issues with some gear purchased "somewhere" and it turned out that these have been ES (engineering sample) CPUs. After replacing those with "regular" ones all these strange things went away. Those also had been V4-Xeons IIRC ...
