This enables -gl unconditionally, which is not desired. What we should
do instead is:

diff --git a/src/qemu/qemu_command.c b/src/qemu/qemu_command.c
index c5275fe0ee..9f44c76d28 100644
--- a/src/qemu/qemu_command.c

         if (virQEMUCapsGet(qemuCaps, QEMU_CAPS_VIRTIO_VGA_GL) &&
+            accel3d == VIR_TRISTATE_SWITCH_ON &&
             STREQ(model, "virtio-vga"))
             virBufferAddLit(&buf, "-gl");
     }
