I agree that option #1 (late affinity check in compute - probably during ComputeManager.pre_live_migration) is the easiest way to go, but could still potentially be racy although it should (for the most part anyway) solve a scheduling race where concurrent live migration requests are made and there are multiple schedulers running which pick the same host for servers in an anti-affinity group.
