There has been previous discussion of virtio, however while virtio is
good for exporting guest memory, it's not ideal for importing memory

virtio is a DMA-based API which means that it doesn't assume cache
coherent shared memory. The PCI transport takes advantage of cache
coherent shared memory but it's not strictly required.
Aren't we violating this by not using dma_alloc_coherent() for the queues?
I don't see what changing this would buys us though, unless
a non-cache coherent architecture implements kvm.
We're preventing people from implementing virtio devices in hardware,
not that anyone's doing that.
