Firstly, make sure you’re using the latest glance client ( https://github.com/openstack/python-glanceclient )
Also, make sure you’re an admin user

Eventual consistency is ok and we only need this to run until we can shutdown the Essex era glance. But the problem I have is that the glance-client doesn't give me full visibility into an image's attributes, or the API won't let me set attributes (like snapshot instance_uuid).

Currently, I don't know of a good way to do this without taxing the network links, or slowing down the snapshots drastically. For now, we have settled on manually syncing the base instances from one region to the others.
