Title:
image to local block device mapping doesnt work but accepted by the
API
Status in OpenStack Compute (Nova):
Fix Released
Bug description:
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.
