Doc Text:
Previously, when a source compute node is back up after a migration, instances that have been successfully evacuated from it when the node was down were not deleted. A result of having the non-deleted instances makes it impossible to evacuate them. With this update, the successful migration status when evacuating an instance is now verified for knowing which instance to delete when a compute node is back up and running again. As a result, instances can be evacuated from one host to another, regardless of their previous locations.

Description Raoul Scarazzini 2016-01-26 06:20:47 EST 
Description of problem:

When an host comes up after its instances has been evacuated it doesn't destroy them. This causes a failure while those instances are evacuated back to this original host.

How reproducible:

Configure instance-ha on an OSPd 8 environment (like it is explained here https://access.redhat.com/articles/1544823) and then make a host evacuate its instances while hardly reset it. Then do other evacuations until the instances turn back to their original host.

Actual results:

Instances fails to migrate.

Expected results:

Instances successfully migrates.
