Title:
  inline flavor migration fails with pre-kilo instances

Status in OpenStack Compute (Nova):
  In Progress
Status in OpenStack Compute (nova) kilo series:
  In Progress

Bug description:
  If instance.save() is used to migrate the flavor from sys_meta to
  instance_extra, this only works in that instance already has an
  instance_extra row.

  In the case where its missing, the update call silently fails to make
  any changes to the database, and you get lots of
  OrphanedInstanceErrors when listing instances, because the instance no
  longer has any flavors.
