I just did that, and it starts the PVM domU, well, the driver doesn't load,
because of this error message:

QLogic Fibre Channel HBA Driver
PCI: Enabling device 0000:00:00.0 (0000 -> 0003)

                                                                      done
and then on the domU:
lspci | grep Q
00:00.0 Fibre Channel: QLogic Corp. QLA2422 Fibre Channel Adapter (rev 02)

shutting down this PVM, and then trying to start the Windows HVM, produces
the mentioned error message.
