Looking at this document:
http://wiki.xensource.com/xenwiki/VTdHowTo

It says to add something like this to the module line:
pciback.hide=(01:00.0)(00:02.0)

My kernel version is:
2.6.27.19-5-xen #1 SMP 2009-02-28 04:40:21 +0100 x86_64 x86_64 x86_64 GNU/Linux

This page talks about VT and my domU is a PV. Does this same pciback apply? 

Thanks,
James
