I just built qemu-2.5 so I can try the virtio-gpu-pci approach. Btw - I found a demo from virtual open system where they show guest graphics on Exynos based Arndale board. It doesn’t show how but maybe it gives a hint http://www.virtualopensystems.com/en/solutions/demos/kvm-on-arndale-exynos/ Thanks for the tips Yehuda > > thanks > -- PMM
