Hi, Bug https://bugs.launchpad.net/nova/+bug/1323578 was closed since the design is add the localhost to the list of targets and not to only migrate to localhost. I think that there is an issue with that since the user will still randomly fail resize with ssh-key errors when they configure nova to work with allow_resize_to_same_host=True which I think is misleading. I opened a new Blueprint to allow configuring nova to resize on same host only: https://blueprints.launchpad.net/nova/+spec/no-migration-resize Thanks, Dafna
