I find that following the instructions here at Xen Wiki = VtdHowTo=20 don't work:

Binding Devices = to=20 pci-stub

If using pv-ops dom0, also can use pci-stub to hide = devices for=20 assignment (example PCI device 01:00.0) * lspci -n * locate the entry = for device=20 01:00.0 and note down the vendor & device ID 8086:10b9 . 

...
01:00.0 0200: 8086:10b9 (rev =
06)
...

* then use following commands to hide it: . 

echo "8086 10b9" > =
/sys/bus/pci/drivers/pci-stub/new_id
echo "0000:01:00.0" > =
/sys/bus/pci/devices/0000:01:00.0/driver/unbind
echo "0000:01:00.0" > =
/sys/bus/pci/drivers/pci-stub/bind

When I tried to "cat /sys/bus/pci/drivers/pci-stub/new_id", it says =
permission denied.

My NVIDIA graphics card is using BDF 01:00.0. When I change directory to =

/sys/bus/pci/devices/0000:01:00.0/, sub-directory driver is not found at =
all.

Then when I put in pci =3D [ '01:00.0' ] for the Windows XP Home HVM =
config, it complains about pciback but I am using paravirt-ops dom 0 =
kernel.

And when I tried the "xm pci-list-assignable-devices", nothing shows up.

I have already specified iommu=3D1 in grub.

Hope the Intel folks can assist in this matter.
