Hello everyone.

I hit a strange behavior in one of my OpenVZ installation.

I have an OpenVZ server running only one VE.
According to my monitoring and to the top command performed on both hardware node and the VE I can see that cpu usage is 10 time more important in the VE than on the hardware node. Same for the load.

I first think about a problem of ressources but it's not the case because I don't limit my VE (not a single failcnt in /proc/user_beancounters).

All my cores are also available in the VE.

Do you have any idea how cpu and load could be higher inside VE ?
I thought that hardware ressource usage will be the sum of all VE + Hardware server. Do I miss something ?


I use Debian 6.0.7 with kernel 2.6.32-5-openvz-amd64

Please find here version of packages

root@host:~# dpkg -l|grep vz
ii linux-image-2.6-openvz-amd64 2.6.32+29 Linux 2.6 for 64-bit PCs (meta-package), OpenVZ support
ii linux-image-2.6.32-5-openvz-amd64 2.6.32-48squeeze1 Linux 2.6.32 for 64-bit PCs, OpenVZ support

Many thanks by advance for all helps or clues that you can provide.

Vincent
