I have just started to try to achieve pci passthru for a BomU so that I can use the host secondary ethernet interfaces directly.

I am running 3.3.1 on Centos5.2 with std packages.

I have detached the card from the host using pciback but have hit an issue with trying to get the DomU to pick it up, it wants both 01:01.0 and 01:01.1 even though they are totally different cards.

It seems that this issue has arisen somewhere between 3.1 and 3.3, to do with VT-d patches. I am not using VT-d, is there a work around that doesn't involve applying kernel or xen patches on either Do0mU or DomU.
