Hi list,

I try to get gfx-passthrough on a laptop. I inserted some patches from
Weidong Han and I'am able to passthrough the primary card (the only gfx
card) to the domU (Linux HVM). To connect to the domU I use the serial console.
I boot the domU but can't see the boot loader (grub) screen.
Later the kernel messages are printed (not on every boot!).
I can start X11 on the console (with the passthroughed card) and see the
kdm screen on the console.
If I read the vga-bios from /dev/mem within the domU it's the same as
in dom0.
My questions:
Where to search for the missing boot console messages?
Has this to do with the FLR?
How can I debug this?

gfx: VGA compatible controller: nVidia Corporation G96M [Quadro FX 770M]

Thanks.

Dietmar.
