lspci is a *nix command to list the PCI devices.
Based on Nick Couchman’s response to my post, you probably do
need VT-d (I’m guessing you’re running HVM guests id you need a dongle).
You probably don’t need the motherboard in the Dell Precision,
just some documented to be supporting VT-d motherboard (should be a list
somewhere on the wiki).
Also based on Nick Couchman’s response, you’ll probably need to
get a separate serial/parallel PCI card. We are using this one: http://www.startech.com/item/PCI2S1P-2-Port-16C550-Serial-and-1-Port-EPPECP-Parallel-Slot-Saver-PCI-Card.aspx
for some Windows machines here (not Xen related, but for passthrough, I don’t
think Linux/Xen compatibility would come into play), but it is not compatible
with DOS, and I don’t know what OS you want to pass-through to. If you want to
pass through to a legacy OS, you are probably SOL unless you can find legacy
drivers for recent hardware or find a way to pass a parallel port directly
instead of the underlying hardware.

VT-d virtualization?
That's what i need, parallel
port (for a donlge) and some serial ports.

I'm not even sure vt-d is
necessary if the VM will be HVM. I tried
to look into this earlier today, because I actually need to pass through a
parallel port, but I didn't have much luck figuring out how (for starters,
no parallel port in lspci).
