Description Stephen Gordon 2015-09-08 14:39:14 UTC 
Cloned from launchpad blueprint https://blueprints.launchpad.net/nova/+spec/migration-fix-resource-tracking.

Description:

Resource tracking for operations that move instances between compute hosts is
broken in Nova. The fix requires some refactoring and tweaking of the data
model so it's discussed in a spec. It's really about fixing of several long
standing bugs.

Comment 3 Stephen Gordon 2015-09-08 14:43:27 UTC 
Per blueprint, last patch merged for Liberty was https://review.openstack.org/#/c/216733 - need to work out what if anything we can verify (probably mostly regression testing?) for Liberty/8.0 and split remaining patches out for Mitaka.
