[Bug 1377958] [NEW] image to local block device mapping doesnt work but accepted by the API
Public bug reported:
When I try to boot an instance with the boot image specified as BDM the
API accepts the request but the instance ends up in ERROR state due to
an exception in the nova-compute. Furter investigation shows that image
to local mapping is not supported in the --block-device parameter at all
but the API does not validate and reject this kind of requests.
