I ran the following query on the engine database:
select images.* from images join snapshots ON (images.vm_snapshot_id =
snapshots.snapshot_id)
join vm_static on (snapshots.vm_id = vm_static.vm_guid)
where vm_static.vm_name = 'lena' and snapshots.description='before
jessie upgrade';
The resulting output is:
image_guid | creation_date | size
| it_guid | parentid
| images
tatus | lastmodified | vm_snapshot_id
| volume_type | volume_format | image_group_id |
_create_da
te | _update_date | active |
volume_classification
