Public bug reported:
Description
===========
Trying to migrate an instance from local storage to a hypervisor that is backed
by RBD results in the error: invalid spec
'b05eafa0-e7da-4637-a47c-cddca5cc381c_/var/lib/nova/instances/b05eafa0-e7da-4637-a
47c-cddca5cc381c/disk'
Steps to reproduce
==================
* Create an instance from an image that is not on a rbd backend on a node that
is configured to store the instance disk locally (as qcow2)
* Live-Migrate the instance to a node that is configured to use rbd as backend.
openstack server migrate --live compute-rbd --block-migration UUID
Expected result
===============
Migration completes successfully
Actual result
=============
rbd import command of base image fails with: Stderr: u"rbd: --pool is
deprecated for import, use --dest-pool\nrbd: invalid spec
'b05eafa0-e7da-4637-a47c-cddca5cc381c_/var/lib/nova/instances/b05eafa0-e7da-4637-a
47c-cddca5cc381c/disk'\n"
The command run is: rbd import --pool vms
/var/lib/nova/instances/_base/4d3facc86af22a33b3ca0eb95c1953c76b72bfaa
b05eafa0-e7da-4637-a47c-

cddca5cc381c/disk --image-format=2 --id cinder --conf
/etc/ceph/ceph.conf
A trace is attached below.
Environment
===========
Nova 10.1.0
CentOS 7.5
Ceph 12.2
Is there any way to migrate a local instance to a rbd backend or is this
not supported?
