PV usually comes in two flavors: device PV, and core PV. The existing PV
ops deal in terms of the latter. However, it would be useful to add an
interface for a virtual bus with provisions for discovery/configuration of
backend PV devices. Often times it is desirable to run PV devices even if
IOQ is a generic shared-memory-queue mechanism that happens to be friendly
to virtualization boundaries. Note that it is not virtualization specific
due to its flexible transport layer.
