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,
