Would you consider including it together with the other roms ? This would definitely increase the out-of-the box experience. I think we don't even need to have a -vga sga switch then. Since sgabios does not prevent output from going to the normal vga, we could always install it, or install when there is a -serial parameter present. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
