I find
that following the instructions here at Xen Wiki VtdHowTo don't
work:
Binding Devices to
pci-stub
If using pv-ops dom0, also can use pci-stub to hide
devices for assignment (example PCI device 01:00.0) * lspci -n * locate
the entry for device 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 = [ '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=1 in grub.
Hope the Intel folks can assist in this matter.

Ng Beng Heng at the University of Michigan
has done it. He's using the same Intel DQ45CB as me.
