Seems the right thing to do. Would be nice to avoid sprinkling KVM details inside hw/pcspk.c though but that is another problem. Looks good (and v3 kernel patch). -- 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
