This is intended to be a real product that customers would use, it is
not a proof of concept. There is alot of demand for this kind of
simplified virtualization infrastructure in the host side. The series
here is the first attempt at making thin host infrastructure and
Zhi/etc are doing it with an upstream-first approach.

From the VFIO side I would like to see something like this merged in
nearish future as it would bring a previously out of tree approach to
be fully intree using our modern infrastructure. This is a big win for
the VFIO world.

As a commercial product this will be backported extensively to many
old kernels and that is harder/impossible if it isn't exclusively in
C. So, I think nova needs to co-exist in some way.
