Hello,

It seems upstream Linux/Gallium3D/Mesa/Qemu/KVM has recently gained virtualized support for 3D/OpenGL hardware acceleration in VMs, allowing using the GPU of the host in VMs.

Components:
	- Linux 4.4 kernel includes the DRM driver for VirtIO-GPU 3D acceleration (needed in the VM).
	- Qemu 2.5 (rc0) includes the VirtIO-GPU 3D mode support (needed on the host/dom0).
	- Gallium3D VirGL driver is included in Mesa git (needed in the VM, supports up to OpenGL 3.3 atm).
	- On the host/dom0 one needs *any* OpenGL driver (for the host GPU obviously), no special requirements there, if I understood correctly.


Has someone looked into this already? How much work would it be to get VirtIO-GPU working in Xen HVM guests? 


Thanks,
