Public bug reported:
In multinode devstack I had an instance running on one node and tried
running "nova migrate <uuid>". The operation started, but then the
instance went into an error state with the following fault:
{"message": "Unable to migrate instance (2bbdab8e-
3a83-43a4-8c47-ce57b653e43e) to current host (fedora-1.novalocal).",
"code": 400, "created": "2019-03-08T19:59:09Z"}
Logically, I think that even if "resize to same host" is enabled, for a
"migrate" operation we should remove the current host from
consideration. We know it's going to fail, and it doesn't make sense
anyways.
Also, it would probably make sense to make "migrate" work like "live
migration" which removes the current host from consideration.
