This ^^ is part of graphics element as follows:

<graphics>
  <gl enable='yes'/>
</graphics> ..

.. and while it's true that just Spice supports OpenGL currently, I'd
vote for a less specific naming. BTW: wasn't virgl implemented for SDL
initially? I know we don't support it, but my point is, what if XYZ
graphics type gains support for something equivalent to virgl? Would we
end up having yet another 'xyzGL' enum? Well, on the other hand, we
already have pciBackend enum to hostdev elem where we report VFIO/KVM
caps for hostdev[@type='pci']/driver/@name.
So I guess it's your call whether to change this or not. The only name I
can suggest right now (if you're out of ideas) is just 'gl'.

Otherwise the code looks good.
