Re: [Xen-users] howto give DomU the pcmcia wlan card from Dom0 ?

[harm <harmweites@xxxxxxxxx>]

again, this is a Just4FUN project.. So stop with all the other BS, ok :)

lspci on dom0:
00:11.1 CardBus bridge: Texas Instruments PCI1225 (rev 01)
05:00.0 Network controller: RaLink RT2500 802.11g Cardbus/mini-PCI (rev 01)

so my grub line looks like:
module          /boot/vmlinuz-2.6.18-3-xen-686 root=/dev/hda1 ro console=tty0 pciback.hide=(00:11.1)(05:00.0)

and /etc/xen/domu.conf has this:
pci = ['00,11,1']
pci = ['05,00,0']

now lspci in domU shows:
00:00.0 Network controller: RaLink RT2500 802.11g Cardbus/mini-PCI (rev 01)

i now issue apt-get rt2x00-source and cd to /usr/src/ to unzip rt2x00-source.tar.gz

cd modules/rt2x00/ and do 'make' and 'make install'

modprobe rt2500pci shows this with 'dmesg':
Loading module: rt2500pci - CVS (N/A) by http://rt2x00.serialmonkey.com
.
PCI: Enabling device 0000:00:00.0 (0000 -> 0002)
wmaster0: Selected rate control algorithm 'simple'

looks like the manual method works better since i now have a wlan0 interace in DomU :)

iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.

sit0      no wireless extensions.

wmaster0  IEEE 802.11g  Frequency:2.412 GHz
          RTS thr:off   Fragment thr=2346 B

wlan0     IEEE 802.11g  ESSID:""
          Mode:Managed  Frequency:2.412 GHz  Access Point: Not-Associated
          RTS thr:off   Fragment thr=2346 B
          Encryption key:off

However, kismet complains that this device cant go into monitor mode... :x

Fascinating!!
So..
[root@pine ~]# lspci
[snip]
02:01.0 CardBus bridge: Texas Instruments PCI1420
02:01.1 CardBus bridge: Texas Instruments PCI1420
and the like...??
Same system has these: (older system does not...)
00:1d.0 USB Controller: Intel Corporation 82801CA/CAM USB (Hub #1) (rev 01)
00:1e.0 PCI bridge: Intel Corporation 82801 Mobile PCI Bridge (rev 41)
Hmm, I may play with this...

Sure, I see pro/con of that now too.

Thanks,
