Windows 2k8 R2 guest with updated virtio drivers is idle inside but on the host qemukvm process uses 7-15% cpu.

Things that have been tried without any significant success
– removed tablet device
– manually set cpu topology for cores per socket

Is it just me or the qemukvm has little tolerance with windows?
