Hi, When I run a centos 5.3 x86_64 guest on my F11 x86_64 system with kvm I see the qemu-kvm process cpu usage jump to ~20% every few seconds even though the guest is completely idle (I even disabled the HAL polling for /dev/hdc). Does anyone have an idea what could be the cause of this or how find the reason for this behavior?
Regards, Dennis

Interesting. I also have an x86_64 CentOS 5.3 guest running under an x86_64 F11 host. But I don't see those spikes. What I see is a constant, apparently very steady 12% CPU usage when the guest is idle. I have not disabled /dev/hdc polling.
My guest has 1 GB of RAM and 2 virtual CPUs, if that matters. I've also messed with xorg.conf to increase the resolution slightly. Otherwise, it is a vanilla virt-manager created VM.

It might help to remove the virtual sound card, I think.
