[Xen-users] Re: X11 in PV domU: limited success

[Chris Epicier <seuchato@xxxxxxxx>]

Hi

In this thread
http://lists.xensource.com/archives/html/xen-users/2008-01/msg00516.html
I achieved partial success with an AGP Matrox G400
graphics card. I switched tha card against a pci
Geeforce MX2. Could configure it straight away by
sax2, so it's up an running now. 

By chance that was the primary graphics card where
dom0 and boot messages were displayed on. I used
/etc/init.d/boot.local script like that to 'steal' the
card from dom0 this way:

echo -n 0000:00:06.0 >  /sys/bus/pci/drivers/nv/unbind
echo -n 0000:00:06.0 > 
/sys/bus/pci/drivers/pciback/new_slot
echo -n 0000:00:06.0 > 
/sys/bus/pci/drivers/pciback/bind
echo -n 0000:00:06.0 > 
/sys/bus/pci/drivers/pciback/permissive

Actually dom0 is running in textmode only, so no nv
module was loaded.

Now i'd like to move on to an AGP card (01:00.0). I
believe, domU should receive control of the AGP bridge
somehow. lspci in my dom0 looks like that

how can I give the AGP slot (dunno if it is the right
term) to domU?
