Public bug reported:
It is not possible to boot the image that was created with nova image-
create from a volume backed instance.
Steps to reproduce:
stack@stack:~/devstack$ nova boot --flavor 100 --block-device source=image,id=70b5a8e8-846f-40dc-a52d-558d37dfc7f1,dest=volume,bootindex=0,size=1 volume-backed

ERROR (BadRequest): Block Device Mapping is Invalid: Boot sequence for the instance and image/block device mapping combination is not valid. (HTTP 400) (Request-ID: req-87ae0d82-65dc-4b7b-ac99-88f70b7fe32c)
It seems that it is only a validation problem on API level as the same
image can be booted with --image parameter.
