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.

        - 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 
        - 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?
