Comment 3 for bug 1771612

Hard to say. Right now, I'd say that unless we manage to get a working fix that won't impose this version restriction between containers and host, we only support same versions between host and containers (or later version on containers). Not newer on host and older on containers.

If we can come up (and atm I am not all too positive about it) with a solution, we would be able to relax this restriction.
