[Spice-devel] Spice OpenGL does not work

[Frediano Ziglio]

The idea of Virgl is to use the host card GPU 3D capabilities to accelerate/provide 3D rendering. 

Your card is mainly a 2D VGA card, really useful for remote system administration but quite useless for Virgl. 
Desktop processors integrate an Intel GPU which is enough for Virgl. 
About ATI/NVIDIA support I'm not sure the support level. dma buffer support is required but seems 
missing in NVIDIA cards. Try asking to Qemu mailing list.
