Yes, the behavior is very strange. So is this intended or is it not? In http://lists.nongnu.org/archive/html/qemu-block/2016-03/msg00526.html you said that it is. I myself would indeed say it is very strange. If I were a user, I would not expect this behavior. And as I developer, I think that how a BDS's child is used by its parent should solely depend on its role (e.g. whether it is "children.0" or "children.1"). Max
