However I did experiment more with it, my graphics card is an GeForce GTX470. I came to the conclusion that passthru works great with XP (both 32bit and 64bit) but giving me issue's whenever Im trying on Windows 7 64bit. It seems that vga passthru doesnt work for the newer qemu-xen model (using Qemu 2.0.0), so Im using qemu-xen-traditional along with the old bundled qemu-dm which works fine for XP. I'll attach my hvm config Im using right now - I'll basically use it for both XP and Win7. I've also a different HVM for other HVM's where I rather use qemu 2.0.0 and Spice, but this is a different topic (nothing todo with VGA Passthru). Basically Im on Gentoo and using Xen 4.4.0-r7, but changed the xen-tools ebuild slightly as it would not build the traditional qemu by default. So any idea why this is not working right for Win7? Win7 also seems to be a lot slower with qemu-xen-traditional, is that a bug in the old model? regards, Georg Am 28.07.2014 04:47, schrieb jacek burghardt: > Well we all pass our video cards as secondary display. *gfx_passtru > does not work.
