@Jay, per "Cinder has added version discovery in Liberty so Nova should
go back to using the 'volume' service type as the volumev2 service type
will go away and version discovery should take care of making sure the
right API version is used." - what is the cinder version discovery
change mentioned?  Is that in cinder - can you link to the patch?

Also, I think this is novaclient which means if the version discovery in
cinder is only liberty, we can't assume novaclient isn't talking to a
kilo cinder.

Title:
  novaclient needs to move to using the 'volume' service type

Status in Python client library for Nova:
  Confirmed

Bug description:
  It appears that there are still places in Nova that are being
  hardcoded to use the Cinder V1 api.  Evidence of this can be seen by
  setting enable_v1_api to false in Cinder and then trying to use any of
  the 'nova volume' commands.  Errors like the following are produced:

  Attempts to run tempest also fail.

  Cinder has  added version discovery in Liberty so Nova should go back
  to using the 'volume' service type as the volumev2 service type will
  go away and version discovery should take care of making sure the
  right API version is used.
