Just FIY everyone who wants up to day kernel and hardware accelerated OpenGL in Windows VM

[pg2web]

I finally tired waiting for Intel SRIOV support in mainline kernels and found the alternative. I suggest to try Mvisor lightweight QEMU alternative and their Windows virtio-opengl driver that uses /dev/dri/ render. It's very close to hardware and will fit most of your needs. I can even run it in podman container for better isolation.
It allows to run very picky Virtualbox based LDplayer android emulator with good FPS as nested->nested guest.

Hi @pg2web I have a fundamental doubt. I'm running Proxmox on a Meteor Lake 125H. GPU to windows vm is not working properly with dkms (error 43). Your suggestion is to install Fedora as main OS, run MVisor and install windows?
