I think this is something that should be addressed in the new block storage project, and only incidentally in glance. Basically, glance can record the intent of X being based on snapshot Y, but building a volume X that is based on some copy of snapshot Y is best left to the block layer. Any solution expressed at the Glance layer is going to be biased towards doing the cloning too early. _______________________________________________ Mailing list: https://launchpad.net/~openstack Post to : [email protected] Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
