I don't know how do you start it, and you didn't provide the command line either.

So it is libvirt. I don't know how to use it.

Either way,

qemu-system-x86_64 -device virtio-vga-gl

will fail with the error message you're seeing. However, e.g.

qemu-system-x86_64 -device virtio-vga-gl
-display gtk,gl=on

works fine. The first variant fails because you asked gl-capable
vga device emulated in guest but did not provide any gl-capable
display backend to output this vga device to. This is a configuration
error. Maybe due to libvirt, I dunno.

Thanks,
