Hi Thang, Vincent,

I guess the root cause is that finish_volume_migration() still
handles a volume as a dictionary instead of volume object and
the method returns dict volume.

And then, 'rpcapi.delete_volume()' in migrate_volume_completion()
tries to delete dict volume but it fails due to the following error.

Not yet. You can go ahead.

- Result of 'cinder migrate --force-host-copy True ....'
