xen pci passthrow

Hello I am trying to passthrow video card in xen.

I am using xen 4.1 fedora 17 and Nvidia 9400GT

pciback supported by kernel as module

When I pass xen-pciback.hide="(01:00.0)" param to grub I got error in dmesg

So I removed it from grub and created modprobe.d/zzz.conf
Then I created initramfs.

Result was: xen-pciback wasn't loaded, nouveau was loaded


I unloaded nouveau and loaded xen-pciback.

I started windows and found video card, installed driver.

But video card marked with yellow color, and I don't have picture on it.

It is a problem of my method "rmmod nouveau, modprobe xen-pciback" or problem of video.

I have build initrafs with dracut, but it doesn't contain xen-pciback.ko

[root@DeltaS boot]# lsinitrd initramfs-3.8.4-102.fc17.x86_64.img |grep pci

How does he know to include xen-pciback.ko, i mentioned it in modprobe.d.
Is it sufficiently?
