I have 3 server with proxmox installed, they are dell 1950
8 x Intel(R) Xeon(R) CPU E5540 @ 2.53GHz 16GB Ram Raid 1

I have 3-5 guests in each, all using Kvm, guests are Centos 4.4 or latest debian OS'es. If some process going wild and takes 100% of cpu the guest freeze for good.
Different kernel different OS'es. I have searched /var/log for errors without any effect.

Can someoine point me a direction where and how solve this problem ?
Thank you.​

Proxmox does not have any logs of such which let me see what happend with the guest os ?
 
are the guests accessible? if yes, find out if there is any process in the guest consuming all power.
 
When freeze comes guests are dead completely. One process is going wild and consume all CPU, however this process is not critical, so i can restart it without any problems. I have around 15 servers like that, and it happens rarely, the only difference is that when OS is installed on classic server i can restart it, if on proxmox, it is a complete Freeze. I have anoher guest which consumed a lot of cpu on boot by mysql, and it was legitimate, on each boot et freezed, what a nightmare.
Is there any way to fix such stuff ?
 
find out which process is going wild and why.
 
The process is mysql, if the guest VM was shut down there are a lot of replication data stored, and on boot it gets a lot of data, and this is perfeclt normal if it takes a lot of cpu some time. I can not fix legitimate process.
 
Hello, thank you for the tip, in the first message i gave wrong info, i was on the kernel 2.6.32-6-pve when i went back to kernel 2.6.32-4-pve all is running perfectly fine.You think same bug ?
 
Doing reply to myself, i dont think it is network related, VM freezing only when CPU spikes to 100% whatever the daemon, for example i had issue with apache, it freezed also, so its not a mysql replication data problem.
