Well, in fact any fixed value is wrong here. By default, qemu-iotests is supposed to use cache=writethrough for everything, and ./check -nocache should make it cache=none. I think what we really want is a ./check option that allows specifying any cache option, and then we should make the scripts honour that option. Kevin
