Yes I have a DL-DVI capable monitor (Resolution: 2560x1440). I don't have monitor with Resolution = 2560x1600 Using - my DL-DVI monitor( = the Dual Link connector on my graphic card GTX680 is connected through a Dual Link cable to my DL-DVI montior) -my GTX 680 gridified to K2 - high resolutions (2560x1440) my domU XP64 is able to boot properly. 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 myconfiguration file is printed out and where the domU XP 64 is started,shutdown. After that the domU XP64 is restarted. http://youtu.be/UgIuPED-h44 No black screen when the domU is started. 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? Is your passthrough GPU the primary in dom0? With gfx_passthru = 1 the boot-up Windows animation is 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.
