If we're talking big crazy changes: Why not take the "small VM
driver" (presumably nova-compute) out of Nova? What stays behind is
_already_ orchestration but missing some features and having a fair
few bugs.
Way back in April[1] ttx asserted:
One insight which I think we could take from this is that when a
smaller group of people "owns" a set of files, we raise quality
(compared to everyone owning everything). So the more we can
split the code along areas of expertise and smaller review
teams, the better. But I think that is also something we
intuitively knew.
