FWIW, an untested branch with the virtio-1.0 patches + some of my
virtio-1.0 stuff on top rebased against current master can be found
here:

The main issues currently are feature bit handling (legacy vs.
transitional vs. modern) and migration. A prereq for fixing the first
is moving host feature bits out of the transport, for which I have a
patch floating around. The rest needs more thought before we can
proceed, I fear.
