Xen users - Sep 2010 - Is there a motherboard with paralell port and VT-d virtualization?

I need a paralell port and rs232 also.
SOmebody know?
thanks!

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).

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).

I belive, most simple (and cheap) solution is separate PCI card with
those ports.

If you''re trying to use PCI devices in an HVM domU, then, yes, VTd is
necessary.  PCI device forwarding without VTd can only be done in PV domUs.

There may be a way to pass through a parallel port without PCI.  One idea is to
use a USB to LPT device and pass through the USB device, since USB passthrough
has better support than does LPT passthrough right now.  On many motherboards,
the LPT and COM devices are attached to a generic PCI device that may have
several other peripherals attached.  So, unless you use a PCI or PCIe add-in
card that has an LPT port on it, you may be out of luck.

U know where i can find that motherboard?
and how do i use those ports on a HVM guest?
lspci?
or there is a driver in xen kernel dom0... i see that in dom0 there is a pci
port "disabled by default"... should be the same for LPT?
thank you

U right! butt i need a pci slot for an special controller card. and one for
the serials.... and one for the paralell . The new motherboards have only 2
standar pci.

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.

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)

I use a system with this Intel board in it:

"Intel Desktop Board DG33BU"
http://www.intel.com/products/desktop/motherboards/dg33bu/dg33bu-overview.htm

The latest flash BIOS update adds VT-d support, has a parallel, serial, and even
floppy connector.

I have an Intel Core2 Duo Processor E8500 (6M Cache, 3.16 GHz, 1333 MHz FSB)
chip in it. Works quite nicely.

Note that parallel port is NOT a PCI device, so you cannot use Xen PCI passthru
(IOMMU/VT-d or not) to passthru it to a guest VM.

You need some other form of "parallel port passthru" if you need to
use it in the VM.

There is a sarial port emulation on the kernel xen options. Is there the
same for paralell?

I don''t know. 

Qemu-dm has serial support for Xen HVM guests, but I don''t know about
parallel/lpt.

Qemu-dm has serial support for Xen HVM guests, but I don''t know about
parallel/lpt.

	In case anyone else stumbles across this thread and can offer
advice:  Even if qemu-dm had parallel/lpt support, it would have to be full
pass-through for what the OP and I need (software key), not emulation.
