Thanks, I'll mark it invalid (meaning "can't reproduce it to get more
information") for now, please do re-open if anyone can reproduce.

Title:
  qemu-system-x86_64 takes 100% CPU after host machine resumed from
  suspend to ram

Status in QEMU:
  Confirmed
Status in “qemu” package in Ubuntu:
  Invalid

Bug description:
  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.
