So focus on interconnecting physical systems I think would be one way
for vbus to stop conflicting with KVM. If drivers for such systems
appear I expect that relevant (hypervisor-agnostic) vbus bits would be
very uncontroversial.

This would not be the first technology to make the jump from attempting
to be a PCI replacement to being an interconnect btw, I think infiniband
did this as well.
