virtio-gpu 3d acceleration changes in qemu
Goal
The upcoming 6.1 qemu release comes with virgl support changes and libvirt should adapt to that.
Technical details
The virtio-vga device has been split into two (same goes for the other device variants). Instead of a single device with virgl={on,off} property there are now two devices: virtio-vga and virtio-vga-gl, whereas the latter is the device with virgl support.
