Public bug reported:

Attempting to attach a volume using an invalid ID currently results in a
HTTP 500 error. This error should be handled and a HTTP 4xx error
returned instead.

  $ openstack server create ... \
     --block-device source_type=volume,uuid=44d317a3-6183-4063-868b-aa0728576f5f,destination_type=volume,delete_on_termination=true \
     --wait test-server
  Unexpected API Error. Please report this at http://bugs.launchpad.net/nova/ and attach the Nova API log if possible.
  <class 'nova.exception.VolumeNotFound'> (HTTP 500) (Request-ID: req-7fe03627-c4ce-4f4b-9d5c-3abd6b88d3e3)

where '44d317a3-6183-4063-868b-aa0728576f5f' is not an UUID
corresponding to a valid volume.
