Changes

*QEMU VirGL currently supports only for Linux guests at the moment [https://wiki.archlinux.org/title/QEMU#virtio (Specifically needs 4.4+ Linux kernel with mesa 11.2+ compiled with the "gallium-drivers=virgl" command option]. Plans are to target "GL2.1 + GLSL 1.20" as the possible lowest GL interface to support. The guest would then expose the same level of GL. This project will [https://docs.mesa3d.org/drivers/virgl.html#future-scope eventually support Direct3D and Windows guest] but there is none at the moment. Currently the renderer is GLSL 1.30 based, and requires some extensions from later GL levels. Current developer only really tested on the open source nouveau driver exposing GL3.0/GL3.1 core profile, and the binary nvidia driver exposing GL 4.3. Future plans to add a capabilities system will be required to work make things work across more systems. The capabilities system will expose different guest GL levels dependant on the host GL level, this could allow for a GLES2 specific interface etc. The current guest driver exposes GL2.1 and GLSL 1.20. Also there is a [https://github.com/virtio-win/kvm-guest-drivers-windows/pull/943 pull request: Windows Virtio GPU 3D acceleration for QEMU].
