Horizon uses openstackclient, so it's compatible with keystone v3.

You just won't be able to use novaclient cli with keystone v3 -- use openstackclient in that case.

Hm, that might be the way to go (leave nova configured with v2). Sorry I don't know more about it. Nova hasn't been updated yet with keystone-v3-specific functionality. But when nova is provided with a v3 token, it can pass that around without knowledge of anything inside it, and as long as keystone v2 will honor the token, it should work fine with nova configured with v2. You might have to try it out a bit to see how it works out. We don't yet have CI jobs set up with nova to run alongside keystone v3.
