It turns out that I was using -device to add the VGA device, and qemu
didn't treat virtio-vga-gl the same way virtio-vga was. See "[PATCH] vl:
add virtio-vga-gl to the default_list".

The reason for the warnings and virgl crash is that the secondary gfx
console GTK widgets aren't realized by the time virgl needs a context. This
is a pre-existing issue (-display gtk,gl=on -device virtio-vga,virgl=on
-device virtio-gpu,virgl=on qemu crashes)
