Comment 3 for bug 1769131

I tested this review in my environment, and with this code in place I could no longer reproduce the issue raised in bug 1769131

Note: In this bug images_type is default (ceph is not being used)

Similar to above, when cold migrating an instance from compute02 to compute01, at the step where it's awaiting confirmation for resize/migrate, the following files can be found:

compute01
/var/lib/kolla/var/lib/nova/instances/
\-- 0d548887-54bd-4e39-b57d-fdbaa05a31db
    \-- console.log

compute02
1 directory, 1 file
/var/lib/kolla/var/lib/nova/instances/
\-- 0d548887-54bd-4e39-b57d-fdbaa05a31db_resize
    \-- console.log

After confirming the migrate/resize, this becomes:

/var/lib/kolla/var/lib/nova/instances/
\-- 0d548887-54bd-4e39-b57d-fdbaa05a31db
    \-- console.log

1 directory, 1 file
/var/lib/kolla/var/lib/nova/instances/

0 directories, 0 files

Excellent !

No disk.info file is present on the source host (and the instance dir is also gone, which it should be)

For example, I was then able to live-migrate the instance (from compute01 back to compute02) since the pre_live_migration checks pass.
