Maybe you can print out what it is doing, then try to figure out if they are doing good. My linux works good, never tried windows.

Windows 2k8 R2 guest with updated virtio drivers is idle inside but on the host qemu-kvm 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 qemu-kvm has little tolerance with windows? _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Well I did. Upstream provides rpms till version 0.12.1.x. Even the RHEV srpm (the one I am using) has the same version. And I don't want to compile both libvirt and qemu-kvm from source since it is the production machine.

Did. Nothing abnormal. A quick perf shows this:

Yeah, I would not compile libvirt and qemu-kvm from source either.
What about this: http://forum.proxmox.com/threads/5770-Windows-guest-high-context-switch-rate...
Did you try this? Doesn't help?
