Description RHOS Integration 2013-12-12 13:30:44 UTC 
Cloned from launchpad blueprint https://blueprints.launchpad.net/nova/+spec/unified-migrations.

Description:

Resize/Migrate/LiveMigrate/Rebuild are all separate code paths. They should be unified to share as much of the same code as possible, as right now they do not. The overwhelming consensus is that coordination of the migrations should be moved to conductor, where we can eventually eliminate the migration state living on the compute nodes and the implicit trust between compute nodes required to pull off a migration.

Comment 2 Stephen Gordon 2014-01-06 16:12:24 UTC 
Require regression testing of resize/migrate/live migrate/rebuild operations.
