    "Future versions of QEMU will begin to require a Rust compiler." - yay! But very surprised there's no anti-Rust comments on the first page (so far). What are the usual naysayers doing?

      The way I understand it, the VirtIO is basically making the VM into a Vulkan client on the host system. There is some overhead but pretty much no need to pass through the GPU anymore.

          My understanding is the virtio vulkan support still requires linux, or anything that works with virgl currently, as I don't think there's a stable windows virtio/virgl driver.

          There is https://gitlab.freedesktop.org/max8rr8/virglrenderer (from this PR) but it hasn't been updated in 1.5 years and still has tons of show-stopper bugs.

            yes but right now only if you have linux as a host and linux as a guest.

            right now it does not work if you have linux as a host and windows as a guest...
