That already exists as part of the virtio driver suite

Because linux already has 9pfs implemented over virtio-pci, so the three
missing pieces are:
 1. qemu: passing the operations over a spice channel (instead of
 directly running them on the host in ./hw/9pfs/virtio-9p-local.c)A
 2. windows driver
 3. client support
