[Xen-devel] Nvidia 9500GT Xen VGA passthru

[Pasi Kärkkäinen <pasik@xxxxxx>]

Hello Peter,

Some people have been asking for tips about Nvidia Xen VGA passthru,
so maybe you could help? 

Could you post the exact steps you did? 

Have you tried with Xen 4.0.x after your initial experiments in 2009? 

Thanks!
