Since the daemon can manage and add (at fresh start) multiple servers, we also should be able to add them from a JSON state file in case of a daemon restart, so post exec restart support for multiple servers is also provided. Patch also updates virnetdaemontest accordingly. Signed-off-by: Erik Skultety <eskultet@redhat.com> Signed-off-by: Martin Kletzander <mkletzan@redhat.com>
