Title:
  If libguestfs hangs when provisioning an instance, nova will wait
  forever.

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  In some situations (using nested KVM in an environment where nested
  KVM support is buggy), the appliance started by libguestfs will hang
  and the libguestfs-launched qemu process will never exit.  This will
  cause the launched instance to get stuck in state=spawning forver (or
  until someone explicitly kills the libguestfs appliance).

  We should wrap the call to guestfs.Guestfs.launch with some sort of
  timeout to detect this situation and at least report an error.
