Just to make sure I'm clear on this ... you're saying that unless I have
VT-d, there is no way I'm going to give a fully virtualized guest direct
access to a parallel port of any kind (either on the mobo or on a PCI card).
Do I have that right?

In a separate thread I've been trying to figure out why my fully virtualized
guest can't access a license dongle on a parallel port, and if this is
correct it sounds like the answer is "You can't."
