Public bug reported:

cinder create --image-id 3dc83685-ed82-444c-8863-1e962eb33de8 1  # ID of
cirros image

nova boot qwe  --flavor m1.tiny --block-device id=d62c5786-1d13-46bb-
be13-3b110c144de7,source=volume,dest=volume,type=disk,bootindex=0

cinder snapshot-create --force=True 46b22595-31b0-41ca-8214-8ad6b81a06b6

cinder snapshot-delete 43fb72a4-963f-45f7-8b42-89e7c2cbd720


Then check nova-compute log:
