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.
