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

> Is this another paravirtualized interface

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.
