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?

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.
