Re: [Xen-users] Is there a motherboard with paralell port and VT-d virtualization?

[Juan Pablo Lopez Bergero <lopezjp@xxxxxxxxx>]

Dustin,

               My OS is a old linux 2.2kernel (mandrake) with a propietary module for a image process card. The pc hardware is a part of a X-Ray machine. And they use serial ports (2 or 4) parallel ports (1 for a donlgle) and 1 pci port (if there are serial and paralell integrated on the motherboard)

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.

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).

Don't know what mobo supports VT-d and has those ports, but whatever
custom motherboard the Dell Precisions (e.g. T3500) has both parallel
and serial ports and has the VT-d option in the BIOS (disabled by
default).
