[Xen-users] VGA passthrough => no screen VGA at th first boot of my domU but all works fine after second..

[Rémi BERNIER <R.BERNIER@xxxxxxxxxxx>]

Hello list,

I'm on linux Ubuntu 10.04 with Xen 4.01
and pvops kernel 2.6.32.27
I have a Dell Lattitude E6500 with VT-D
activated.
I have passthrough all my USB port and
VGA display in my domU Windows XP but i have a little problem with the
VGA display, 
when my HVM Windows XP start, I haven't
the first time the VGA screen, i must restart the HVM to have it... strange
!
This is my config file of my domU:

kernel='/usr/lib/xen/boot/hvmloader'
builder='hvm'
memory=1024
name='XP'
vcpus=2
vif=['type=ioemu, mac=xx:xx:xx:xx:xx,
bridge=eth0']
disk=['phy:/dev/data/XPC,hda,w', 'phy:/dev/data/XPD,hdb,w']
device_model='/usr/lib/xen/bin/qemu-dm'
boot='dc'
gfx_passthru=1
pci=['00:02.0','00:02.1','00:1b.0','00:1a.0','00:1a.1','00:1a.2','00:1d.0','00:1d.1','00:1d.2','00:1d.7']
#vnc=1
#vncviewer=0
#vncdisplay=1
#nographic=0
#usbdevice='tablet'
#keymap='fr'

In the xend.log, I have just a Warning
message:
[2011-01-26 13:35:14 3968] WARNING (pciif:423)
pci: 0000:00:02.0: it is on bus 0, but has no PCI Advanced Capabilities
for FLR. Will try the Dstate transition method or some vendor specific
methods if available.
The pci: 0000:00:02.0 is my VGA card.

Someone has already encountered this
problem ? I have tested with the line gfx_passthru=0 but nothing to do.
Thanks in advance for your answer.
Regards,
Rémi
