Title:
  snapshot mode is broken for raw images

Status in QEMU:
  Fix Released

Bug description:
  The snapshot mode is not working if you use raw format for image
  instead of qcow2. Create a raw disk image by running "dd of=xxx.img
  bs=1 count=0 seek=8G". Then run "qemu -snapshot xxx.img". In monitor
  console run "info block". There should be qcow2 temporary image backed
  by the raw image. Now run "commit ide0-hd0" and after that again "info
  block". You should see now that there is no more image, so any
  operations on it will fail form now on. This is for latest HEAD in
  git.
