Enable opengl virtio-gpu virgl vulkan in windows build
Goal
Presently, there seems that GPU/HW graphics acceleration is not enabled for qemu windows build. This issue is filed to document the progress of the request to Enable virgl/ make virgl work for linux guests on windows-host
Thx
Technical details
I read recently that
- Microsoft merged d3d12 backend into Mesa-21, perhaps as part of its WSL2/WSLg effort.
https://www.phoronix.com/scan.php?page=news_item&px=Mesa-21.0-Direct3D-12-Gallium3D - Google venus project merged into qemu mainline.

So wouldn't linking qemu with a Mesa libary, enabling d3d12 backend, enabling virtio-gpu do it ? https://github.com/pal1000/mesa-dist-win
