And what kind of support does this require in the guest? Is this another paravirtualized interface (along the lines of Xen's frontend/backend interface)?

You load drivers in the guest for various IO subsystems (network, disk, etc)

Yes, though it is not entirely orthogonal. For instance, it is possible to tunnel existing PV protocols
over it (e.g. virtio-net). This means you swap out the low-level protocol (virtio-pci is exchanged
for virtio-vbus) but the higher layer PV drivers (virtio-net, virtio-blk) remain unchanged.
