Comment 8 for bug 1540692

I've updated from 16.10, and my host is now running Ubuntu 17.04 with all packages up-to-date, including the following:

     qemu (2.8+dfsg-3ubuntu2)
     libvirglrenderer0 (0.5.0-2)

As mentioned in comment #7, my QEMU commands include the following:

    -vga virtio \
    -display gtk,gl=on \

And when I try to start my VM using commands including the above, I still get:

     qemu-system-x86_64: -display gtk,gl=on: GTK support is disabled

I'm not certain, but I think that, for the VirtIO GPU 3D (Virgil) to work, mesa must be compiled using the "--with-gallium-drivers=virgl" option. See https://wiki.archlinux.org/index.php/QEMU#virtio

So maybe the problem isn't with qemu, but instead with mesa being compiled without the "--with-gallium-drivers=virgl" option being set. Any thoughts?
