Re: [Xen-devel] Xen Paravirt Operations Domain 0 Serial Console Problem

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.

I have both the onboard Intel GMA 4500 and the PCI Express x16 NVIDIA Geforce 8400 GS.

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