Hi all
after my success with a rather outdated system (see
http://lists.xensource.com/archives/html/xen-users/2008-02/msg00643.html),
i tried on a new box:
Asus M2N WS Pro, Athlon 64 X2 4600+, 4G Ram, 3x Sata
Raid 5, LVM, Suse 10.3, kernel 2.6.22.17-0.1-xen SMP
i686 athlon i386 GNU/Linux, xen 3.1
lspci | grep VGA
01:00.0 VGA compatible controller: nVidia Corporation
GeForce 8600 GT (rev a1)
02:06.0 VGA compatible controller: ATI Technologies
Inc 264VT [Mach64 VT] (rev 40)
hidden away from to dom0 through
/etc/init.d/boot.local:
# hide 8600 GT so it can be used in domU (not
activated as of 080117)
slot=0000:01:00.0
echo -n $slot >
/sys/bus/pci/drivers/pciback/new_slot
echo -n $slot > /sys/bus/pci/drivers/pciback/bind
echo -n $slot >
/sys/bus/pci/drivers/pciback/permissive
#02:06.0 VGA compatible controller: ATI
Technologies Inc 264VT [Mach64 VT] (rev 40)
slot=0000:02:06.0
echo -n $slot >
/sys/bus/pci/drivers/pciback/new_slot
echo -n $slot > /sys/bus/pci/drivers/pciback/bind
echo -n $slot >
/sys/bus/pci/drivers/pciback/permissive
domU config
name = "lic"
kernel = "/boot/vmlinuz-xen"
ramdisk = "/boot/initrd-xen"
memory = 512
vif = [ 'mac=aa:cc:00:00:00:CA, bridge=xenbr0' ]
disk = [ 'phy:system/lic-32bit,hda1,w' ]
root = "/dev/hda1 rw"
#remove xencons=tty to avoid VT errors when starting X
#extra = "3 xencons=tty"
extra = "3"
# nVidia Corporation GeForce 8600 GT
# pci = [
'01:00.0','00:0a.0','00:0a.1','00:0e.0','00:0e.1' ]
# ATI Technologies Inc 264VT [Mach64 VT]
pci = [
'02:06.0','00:0a.0','00:0a.1','00:0e.0','00:0e.1' ]
in above sample the ATI Mach64 VT is delegated to
domU.

(II) Module int10: vendor="X.Org Foundation"

interface.
Fatal server error:

(0x000a0000,0x10000) (Bad address)
I get a similar error when delegating the 8600 GT to
the domU (Jfyi: the delegation works as described
above, but with 01:00.0 instead of 02:06.0. pci
delegation works for sound and usb):
tail Xorg.0.log.old
(II) NV(0): Initializing int10
(EE) NV(0): Cannot map SYS BIOS
(EE) NV(0): Failed to initialize the int10 module;
this screen will not be initialized.
(II) UnloadModule: "nv"

(II) Unloading /usr/lib/xorg/modules//libint10.so
(EE) Screen(s) found, but none have a usable
configuration.
Fatal server error:
no screens found
It looks as video memory is not accessible in domU. Do
I have to set some quirky stuff? If so where and what?
