Jean,

Now I am trying to make this patch works on Q35 box too, but I still don't find the code that is graphic card dependent.

Would you tell me where we should fix to make it works on Q35 box?

Regards,

I have two questions.

1.
I tried to create domU(WindowsXP-SP2) with this patch.
The domU was created, but domU did not appear on the display.
How do I see domU?

You should see the display on the monitor at least in VGA (4 bits colour).


2.
After domU was created, I tried to kill domU(WinXP).

$xm shutdown WinXP

but WinXP had still existed.

$xm list
Name               ID
Domain-0           0
WinXP               1

Why?


domU configuration file:
pci = [ '03:02.0' ]   (03:02.0 is principal graphic card.)
vga_pass_through=1

The option is vga_passthrough with my patch.


kernel option:
pciback.hide=(03:02.0)



Mark,

The problem is right now we re-execute the native VGA bios in the guest, so this patch is very graphic card dependent.

Right now as far as I now it's only working fine with a intel 5400 chipset with the embedded ATI ES 1000.

We are currently trying to make it works on a Q35 box.

Regards,
