High CPU load in linux VM after migration to another Proxmox

[AEF]

Hi everyone!

I had to migrate Linux VM with Squid from Poxmox 4.1 to Proxmox 4.2. After migration cpu load extremly increased.
I made clone on Proxmox 4.1 to shared NAS which connected to the both of the Proxmox. In Proxmox 4.2 created VM with he same parameters, after that I moved virtual HD to a new created VM. OS started with no troubles. But cpu load extremly increased.
Has anyone encountered such a problem?
