Hi, I am also encountering the bug of high cpu usage for a windows guest after suspend resume of my ubuntu host. Problem was in 13.04 but it's also still there in 13.10. The windows guest has virtio / spice enabled. Linux guests do not get the high cpu usage. Are there any more logs required or is investigation going on upstream ? I am not sure where to look or curious whether there are other workarounds.

All works fine in 12.10. But after upgraiding to 13.04 i have to restart the VM each time i resuming my host machine, because qemu process starts to take CPU cycles and OS inside VM is very slow and sluggish. However it's still controllable and could be shutdown by itself. According to the taskmgr any active process takes 99% CPU. It's not stuck on some single process.
