Re: [Xen-users] xen, pvops & nvidia graphics

Hello.

I have this exact same problem myself.

(I have four onboard gigabit network cards, pci 05:00.0, 06:00.0, 07:00.0 and 08:00.0)
I tried using pciback.hide=(06:00.0)(07:00.0) . And in dom0, I now get:

xen ~ # ifconfig eth1
eth1: error fetching interface information: Device not found

And the same for eth2. So it apparently got "hidden", or detached.

But the command "xm pci-list-assignable-devices" doesn't return anything. And when trying "xm pci-detach", I get the same error as you (Cannot detach when pci platform does not exist). Even though I've compiled in all the support I can think of in the kernel.

Running:
Gentoo 2.6.31-xen-r10
xen-3.4.2-r1

Still no luck with that. My grub entry looks like so:

menuentry "Xen-Unstable / Kubuntu 9.10 kernel 2.6.31.6 pvops" {

insmod ext2

set root=(hd0,1)

multiboot (hd0,1)/boot/xen.gz dom0_mem=1048M iommu=force

module (hd0,1)/boot/vmlinuz-2.6.31.6-xen xen-pciback.hide=(01:00.0)

module (hd0,1)/boot/initrd.img-2.6.31.6-xen

}

but my lspci still looks the same (i.e. it still has the line: 01:00.0 VGA compatible controller: nVidia Corporation G96 [GeForce GT 130M] (rev a1)).

Using xm pci-detach still gives the same error as well (Error: Cannot detach when pci platform does not exist)
