** Description changed:

  I have Windows XP SP3  inside qemu VM. 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
- stucked on some single process.
