Hello to everyone.

I would like to configure the VGA Passthrough on the Debian SID because I want to use Debian on the first monitor and Windows 7/8 on the other one. I have tried with XEN and with KVM but in both case I haven't been able to reach the goal. So I need the help of someone more experienced than me.

These are the hardware specifications of my system:

I have two graphic cards installed :

I've already tried by myself to reach the goal,following this tutorial :
