[Xen-users] hvm instance crashes when X is running

["Thomas Schwarz" <tschwarz@xxxxxxxxxx>]

hi all,

i have a strange behavior on opensuse 10.2 GM.

kernel-xen-2.6.18.2-34
xen-3.0.3_11774-20

when i try to setup a fullvirtualized xen instance, the vm crashes randomly 
during installation.

i found out, that always before the crashes my X Server Screen gets corrupted a 
little bit.
i switched to runlevel 3 and tried again and everthing worked. to make sure 
that it wasn't luck, 
i reinstalled and everything worked again

so i guess, that the problem lies in my shared memory GPU (Intel 945gm using 
i810 driver)
i suppose that the GPU and the xen instance use the same memory.

Is there a way to fix this?

thanks for your help,
tomás

my xen config:

 disk = [ 'file:/var/lib/xen/images/vm2/hda,ioemu:hda,w', 
'file:/home/tschwarz/isos/WindowsXPPro.iso,hdc:cdrom,r' ]
memory = 512
vcpus = 1
builder = 'hvm'
device_model = '/usr/lib/xen/bin/qemu-dm'
kernel = '/usr/lib/xen/boot/hvmloader'
name = 'vm2'
vif = [ 'type=ioemu,mac=00:16:3e:64:c7:4a' ]
stdvga = 0
sdl = 1
vnc = 0
vncviewer = 0
ne2000 = 0
localtime = 0
on_poweroff = 'destroy'
on_reboot = 'destroy'
on_crash = 'destroy'
boot = 'd'
