A lot of developer-centric focus discussion on how Docker would work (hint: it does), but VirtualBox is still pretty common in the sysadmin world and other industry circles. Moreover, there seems to be no way it will ever work. It will be interesting to see how that turns out.

Author here. That's a major point of the article - "are we screwed?" I'm not an expert on virtualization but I wanted to see some discussion on this topic, because it feels like we might be screwed and nobody is talking about. Anyway I was happy to see Docker worked, at least on a basic level.

Cool. Thanks for writing it. It summarizes and collects a lot of issues we were all grumbling about here and there. The main hurdles for Docker are organization, not technical. However, the other issues you bring up are going to be more technical (same as you, though, not a hypervisor expert and/or we're going to be at the mercy of big vendors like Apple, Oracle, and Microsoft. Those are much harder problems to overcome.
