Virtio was discussed at good length last year on a previous version. I did implement a virtio version that extended virtio to use memory regions for importing host memory into a guest. http://www.mail-archive.com/qemu-devel@nongnu.org/msg25784.html However, Anthony thought the memory regions broke the DMA engine model of virtio too much and so I went back to PCI.
