Does sendkey from monitor works? qemu-kvm-0.11.1 is very old and this is
not total freeze which even harder to debug. I don't see anything
extraordinary in your logs. 4643 interrupt per second for 4 cpus is
normal if windows runs multimedia or other app that need hi-res timers.
Does your host swapping? Is there any chance that you can try upstream qemu-kvm?
