VFIO is a great thing, and we all want it. But it's also a big project
now as it has to please more and more use cases. I think it will require
some more time to settle its interfaces, and it should likely take this
time. So we need KVM device assignment upstream as well until comparable
VFIO support is in every recent distro kernel out there.
