Hi Anton,

I am no VT-d expert, as I own an AMD X2 based system and there is no VT-d (IOMMU) available :-/ But I've found out [1] that you need to add a special option into your grub.conf / menu.lst to enable VT-d. In the kernel line (the one with xen.gz in it) you need to add iommu=1 to enable VT-d. I am not sure, but afaik there should be an option in the bios too, to enable VT-d.

Hope this helps,
Age_M
