We don't have such a change-state handler, do we? > or perhaps > the notifier chain I have in my shared memory world: > https://lists.gnu.org/archive/html/qemu-devel/2017-06/msg06459.html The postcopy_notify() can do this as well. I just need a way to hook up all the system modules for migration. In our case, it's only RAM, but I think maybe one day we need block support. So as long as the mechanism (either current SaveVMHandlers interface, or postcopy_notify) can do the notification, IMHO it'll be fine. -- Peter Xu
