Title:
  block device mapping transformation doesn't handle "image" source

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  I hit this while implementing volume snapshots for the NFS Cinder
  driver.  I booted an instance from an image with the destination as a
  volume.

  nova boot --block-device id=fc19829e-5f65-4e9c-
  acf3-0e898747506f,source=image,dest=volume,size=2,bootindex=0,shutdown=preserve
  ...

  Creating a volume snapshot for this case will run down
  _volume_refresh_connection_info in LibvirtDriver, which fails in
  DriverVolumeBlockDevice's _transform, which only allows 'volume' as a
  source type.

  It looks to me like this code should allow 'image' as a source, but
  I'm not an expert in this area in Nova...
