Dom0 (NetBSD) / DomU (Linux) - PCI Access

[Victor Dorneanu <victor%dornea.nu@localhost>]

Hello port-xen!

Here are some technical details:

Xen configuration:
-----------------------------------------------------
a) Dom0
   - NetBSD 5.0 / Amd64 (with CURRENT kernel sources)
   - Kernel: XEN3_DOM0

b) DomU
   - Debian/Lenny unstable
   - Kernel: vmlinuz-2.6.18-xen


PCI devices:
------------------------------------------------------
[root@BlackTiny:/#] pcictl pci2 list
003:00:0: Intel PRO/Wireless LAN 4965AGN Mini-PCI Adapter (miscellaneous 
network, revision 0x61)



Using this paper (http://www.netbsd.org/ports/xen/howto.html) I added 
following lines to my grub configuration:
------
...
title Xen 3.3 / NetBSD (hda0, vga)
root            (hd0,1)
kernel         (hd0,1,f)/xen dom0_mem=1800M
module       (hd0,1,f)/netbsd-XEN3_DOM0 bootdev=wd0f ro console=tty0 
pciback.hide=(03:00.0)
....
------------


I rebooted into the Dom0 and I was unable to use the PCI device (as 
expected). Afterwards I added following to my xen-domain file:
------
pci = ['0000:03:00:0']
------------

Then I started the linux-domain... Unfortunately "lspci" did not show 
the PCI device.
Do I have to add extra modules to the DomU-kernel or am I missing something?

I just want to share my WLAN card with the domU. Am I overcharging or is 
there any simple solution(s)?


Greets,
