* Don't advertise information on the network without consent of the user, either through manual configuration, or a user interface that drives this option. * Since libvirtd must be configured for network access anyway (for all but ssh), this setting was not useful "out of the box", so changing this default setting does not remove "out of the box" functionality.

# socket permissions), or if there is a lower layer in

# the network providing auth (eg, TLS/x509 certificates)
