Hi All, As I mentioned, here is the Intel IGD Passthru in action, that's fully working without any issues, with QEMU/KVM running hardware-accelerated Android-x86 5.1/Lollipop : https://www.youtube.com/watch?v=PBN1DmarJ7k
Thank you all once again for the wonderful work on QEMU/KVM/XEN since many years!
