Changes made with net-edit on a running network won't take effect until the network is restarted, so net-dumpxml won't show the changed config right away for a running network. Libvirt doesn't support changing the configuration of a running network, so any changes will require a network restart with net-destroy; net-start. This should be documented better. - Cole
