We discussed this before, and I still think this could be directly derived

I prefer keeping it simple. Much of abstraction in virtio is due to the
fact that it needs to work on top of different hardware emulations:
lguest,kvm, possibly others in the future. vhost is always working on
real hardware, using eventfd as the interface, so it does not need that.
Actually, vhost may not always be limited to real hardware.
We may on day use vhost as the basis of a driver domain. There's quite
a lot of interest in this for networking.
At any rate, I'd like to see performance results before we consider
trying to reuse virtio code.
