Description Eduard Barrera 2015-08-05 06:35:11 UTC 
Description of problem:

Appears that we formally don't support live migration of instances from Havana to Icehouse where they reside on shared storage :

 284     def _check_live_migration_api_version(self, server):
 285         # NOTE(angdraug): live migration involving a compute host running Nova
 286         # API older than v3.23.1 as either source or destination can cause
 287         # instance disks to be deleted from shared storage
 288         if not self.client.can_send_version('3.23.1'):
 289             raise exception.LiveMigrationWithOldNovaNotSafe(server=server)
