Looking more closely I think some of it is certainly appropriate to be

I hope and expect the nova and vgpu_mgr efforts to ultimately converge.
First, for the fw ABI debacle: yes, it is unfortunate that we still don't
have a stable ABI from GSP. We /are/ working on it, though there isn't

simpler i

Unfortunately not, the fw ABI is the unsolved problem, rust is our
