I am mistaken (Apologies!). The boot-up animation doesn't appear on the VNC
console. I tested it an re-checked it on both XP 64 and Win 7 64.

High resolutions is taken into > account Right, OK. So you can achieve the DL-DVI mode without problems on your setup. Which means the problem isn't universally applicable to Xen 4.3.0 + modified GTX680 + XP64 domU. Which begs the question of what is different about my setup... > To avoid any misunderstanding I added a short youtube video where my > configuration file is printed out and where the domU XP 64 is > started, > shutdown.

The issue on my setup isn't about _starting_ the domU - if I get the domU started in low-res mode, changing to a higher res-mode puts the monitor to sleep. When the confirmation dialog box times out, it reverts back to original low-res mode, and the monitor wakes up again. >>Hang on - are you saying that once the Nvidia driver is installed > >you can use gfx_passthry=1 an you get the SeaBIOS output and the > >boot-up Windows animaption on the domU monitor, rather than on > >the VNC console?

I _may_ be wrong here, but doesn't the gfx_passthru=1 get ignored in that case? If it was working, the BIOS level and bootup output should come up on the passthru GPU, should it not? I guess gfx_passthru=1 just disables the emulated Cirrus VGA, but in that case the boot-up animation shouldn't show up on VNC. So I'm not sure what is going on in this case.
