Comment 6 for bug 1657774

Has this bug been fixed in some other way? I think I ran into it on Queens when I tried to do a "nova live-migration-force-complete <id>".

The result was a big mess, with the VM left in some half-migrated state, because this error stopped processing of the migration in its tracks. The VM was running on the target host, but nova thought it was still migrating. The volume attachments were duplicated: once for the target, once for the source. We needed to remove the old attachments and change the nova database directly to fix the state.
