Merge lp://qastaging/~anso/nova/imgcopy into lp://qastaging/~hudson-openstack/nova/trunk

This allows a simplistic version of multi-region. For use until glance/swift become the image store.

lgtm

This looks a bit odd to me, to be honest. We're only syncing images, not the entire objectstore content (right?), so the references in the json (to the original S3 location) will be invalid.

This really looks like something that should happen by consuming the existing API's, not by hacking things on the backend. So, it could do a DescribeImages, find the original location of the registered images from that, copy those over to the other region's object store and register them there. People used to EC2 won't expect images to have the same AMI's across regions, so this is something consumers of the services should be prepared to handle anyway.

I don't see what's wrong with having a hack in place allowing multi-region until the image store is in place.

This one has been around for a while, are we lacking consensus to get this merged ?

Do we still want to merge this ? If yes, since there is no blueprint around this, please provide some insight on why we need this for Bexar, and a quick analysis of the (lack of) regression risk.

past-FFe, do not merge this in Bexar. To reconsider for Cactus.

Bexar GammaFreeze has kicked in, deferred to Cactus. Setting to "Work in Progress" to clear the review queue. Feel free to set back to "Needs Review" once Cactus opens up (of if this issue gets promoted to a release critical one).
