Very interesting; is there anything similar for Vulkan? Does this also work with Vulkan?

  It's called Venus: https://docs.mesa3d.org/drivers/venus.html https://docs.mesa3d.org/drivers/venus.html But not sure how far along it is. virt-manager doesn't seem to be aware of it yet.

    ChromeOS uses it for Steam support which is generally available now, as well as for Android apps, so it must work reasonably well: https://chromeos.dev/en/posts/improving-vulkan-availability-with-venus https://chromeos.dev/en/posts/improving-vulkan-availability-...

      Why does ChromeOS need virtualization for Steam in general?

        Security, defense in depth.

  Vulkan doesn’t come into play here. Vulkan is a graphics API. This project is hardware GPU virtualization in QEMU / libvirt.

    That's incorrect, the goal of VirGL is pass the GL commands themselves (Gallium intermediate representation of them, actually), from the guest to the host, so they are executed on the host accelerated Mesa stack. It is not about virtualising the GPU hardware itself. So it makes sense to one day do the same for Vulkan, which is much lower level and might be able to extract more performance.

  Gfxstream, used by the android emulator and others.
