Huge CPU Time for qemu-kvm process


#1

Hello all,

KVM Qemu is running under CentOs 6.2.
I have 15 VMs running under my KVM host.

All VMs are running correctly but I seen a strange value under TIME using top command :

Take a look at time field for PID 20683 and 29187.

I don’t know why the time is very high.
Currently, the only way I found to fix this issue is to reboot the VM. The problem is this appear time to time and I would like to fix it permanently.

Do you have any idea to fix this ?

If you need more information, please tell me. I’m a novice in KVM Qemu.

Thanks in advance for your help.
