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

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.
