Check out VirGL and the virtio-gpu projects. Is already available in qemu if you're willing to do some work. Virtualized OpenGL (and soon Vulkan?) access to the host GPU inside the VM.

e: my memory slips me, I've already run vulkan apps in qemu.

Granted this was ChromeOS[0], but ultimately it's the same qemu. You just need the right flags and for the guest to have a mesa driver aware of virtio-gpu.

Chromeos uses crosvm, not qemu. Qemu uses virgl to provide opengl, but I think vulkan is still in the works. You can use crosvm on Linux too,works pretty well, it uses a newer version of virgl to provide vulkan.
