That does indeed sound like a "lost interrupt" scenario. (the mouse
movement will make an interrupt to the guest, which "wakes it up", and
once it's awake, it will recover from whatever it was waiting for). 

Unfortunately, I can't guarantee that it works, but try a recent version
of xen-unstable if you can. It may solve it. 

Is this a AMD-V or VT system?
