Hello,

Last 3-4 days (maybe more), using htop or atop i noticed a strange thing:

Htop or Atop inside every OpenVZ CT shows a different cpu usage, but all cores of this CT have exactly the same % usage.

On the host, htop and atop show usage on all cores correctly. I'm running only OpenVZ CTs,
I didn't find in logs files (daemon, syslog .... ) anything strange,

Code:

This night i rebooted this server with previous kernel version (pve-kernel-2.6.32-28).
Everything was okey, htop shows usage of every core separately.
Reinstalled and returned to pve-kernel-2.6.32-29, same problem.

Something wrong with pve-kernel-2.6.32-29 on my hardware !? (HP Proliant DL120 G7 - E3-1230)
