Xen users - May 2008 - VT-d success - passing PCI TV tuner to Windows DomU

Hi all,

Thought I''d share my success with VT-d. I picked up an Asus P5E-VM DO
motherboard as it was relatively cheap and had an extra PCI slot compared to the
Intel Q35 board. The people on #xen IRC were very helpful. I wasted 2 days
trying to get things working on Ubuntu and OpenSUSE with forward patched
versions of Xen for newer kernels. Ended up using CentOS 5.1 which has the
requred 2.6.18 kernel and compiled from the mercurial source. I iniitially tried
compiling Xen in the prepackaged Centos installer Dom0, but the resulting xend
would show ACM errors even though ACM was turned off in the compile options. I
ended up blowing the install away and installing vanillia CentOS 5.1 without the
prepackage Xen and the compile worked fine.

Wasted a few hours because the VT-d wiki was missing the vtd=1 kernel option. I
updated the wiki to include vtd=1 it as well as added the Asus mobo as a
supported mobo.  Hope it saves others some time. I''m surprised how well
it''s working, I''m passing a TV tuner card to my Windows XP SP3
DomU and it works just as well as my old native Windows install. I''m
currently having some issues with the GPLPV drivers but I have outlined my
issues in James Harper''s release thread.

I''m trying to achieve a similar thing, but with a firewire DVB-C card
(Floppy/FireDTV). Would that be possible with the appropriate vt-d setup?
