Title:
  Image perpetually in "SAVING" state if snapshot fails to create

Status in OpenStack Compute (Nova):
  Invalid

Bug description:
  If a user tries to create an image from a snapshot (e.g., through
  Horizon), and the process of creating a snapshot fails (e.g., nova
  fails to extract the KVM snapshot to a disk because there isn't enough
  room in the temp directory), then the resulting entry in "nova image-
  list" will always be in the "SAVING" state.

  It would be easier for ops to identify that a problem has occurred
  with the snapshot process if, when a failure like this occurred, the
  state of the new image was changed to some kind of error state.

  I encountered this problem with essex, but looking at the code in
  trunk as of today, it doesn't look like there's any exception handling
  code in nova/libvirt/driver.py:snapshot when snapshot.extract fails.
