Thanks for the clarification, sounds like what we have currently is
worse than useless in a sense, as it implies OVF support that just
doesn't exist.

However from an API back-compat point of view, I wonder have we missed
the boat in terms of replacing ovf with ova in the v2 API - or is the
door still open to making changes such as this to the v2 API? (given
that it was still somewhat work-in-progress in the Folsom release)
