Yeah, just try using OVF with containers and you'll discover how much of a round peg/square hole fit you are describing. VM's and containers are surprisingly different.
Is what I should have quoted in my reply. Nobody was talking about using one instead of the other. Though, it'd be easy enough to run, for instance, CoreOS from an OVF image to run containers from. Though, I feel like you and I are just stating the obvious at this point. Wouldn't you agree?
