The check that is tripping you up on is assuming that if product == 0, the user didn't specify any product in the xml. The thing to do is to initialize 'product = -1' at the beginning of that function (and add a quick comment that '0' is a valid value), and then update the checks at the end of the function accordingly. - Cole -- Libvir-list mailing list Libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
