We discussed this in our team meeting today and it appears that the source of the problem is a misunderstanding based on Sean's commit message.
Sean had made that comment because we only test N with N-1. So, that is the only tested configuration. There is no reason that we know of, however, that using Nova with older versions of Cinder wouldn't work. Assuming that versioning works the way that it is supposed to, then other combinations should work. We, however, don't recommend using combinations other than Nova at N and Cinder at N-1 as that is what is tested.
Let me know if you have further questions.
Cool, thanks Sean/Jay for discussing it. As noted in the original email, I want to remove the old Cinder Queens compat code from the compute API in Stein anyway, so I plan on doing *something* there, at least dropping it and providing a release note - at most maybe a nova-status upgrade check to make sure Cinder 3.44 is available before upgrading to Stein. -- Thanks, Matt
