I play this part
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

I adapted this with my config like
# lspci -n | grep 01:00.0
01:00.0 0300: 10de:06cd (rev a3)
But I don't have the directory pci-stub, only pciback

And my kernel config
title Xen 4.1.0                                                                 
root (hd0,4)
kernel /boot/xen.gz
module /boot/kernel-2.6.34-xen-r4 root=/dev/ram0 real_root=/dev/mapper/isw_dcgdj
hjbdg_Raid55 dodmraid dolvm domodules ro nomodeset pci=resource_alignment=01:00.
0 xen-pciback.hide=(01:00.0)
module /boot/initramfs-2.6.34-xen-r4

But I am not sure that is work well.
I tried modprob pciback then

xm pci-list-assignable-devices

Without good result

What I do wrong ?
Do I play again any part of Doc ?

Simple question, did you hide the right PCI device ?

Run lspci to get the list of devices, no need to remove the pci hide, run it straight in dom0


Fr translate:

Vérifies que ta carte graphique est bien celle que tu cache.

lspci dans le dom0 te donnera la liste des adresse et cartes.
