Thanks jichenjc,  This bug is because of python-novaclient version
difference

as you said we need to backport https://review.openstack.org/#/c/165932/
to stable/kilo to resolve this bug.

** Project changed: nova => python-novaclient

** Changed in: python-novaclient

Title:
  Fail to boot VM from image with one ephemeral disk

Status in python-novaclient:
  Confirmed

Bug description:
  Kilo latest code

  I attempt to boot a VM from qcow2 image, and also create one ephemeral
  disk, but my request is refused by nova-api.

  [root@icm ~]# nova boot --flavor 1 --image cirros --ephemeral size=2 zhaoqin
  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-6e272b55-a20e-4e1c-9b76-c1fb9d232fa6)

  
  The error is raised from _validate_bdm() in nova/compute/api.py.  Since there is only one ephemeral disk in block_device_mapping_v2 list and its boot_index is -1,  boot_indexes becomes an empty list. And the error is raised, because 0 is not in boot_indexes list:

          if 0 not in boot_indexes or not _subsequent_list(boot_indexes):
              raise exception.InvalidBDMBootSequence()
