Yes, this does sound a little bit premature given that even from the
libvirt POV we're not calling this production ready yet. If you want
to get a headstart on BHyve support in the Nova libvirt driver, then
I'd suggest a short term strategy of maintaining a fork of the Nova
code on github/stackforge, with a clean series of patches for BHyve
changes to libvirt. When we see this is getting to a useful level of
functionality, then it can be submit for review in Nova proper.
