>#          For non-TCP or TLS sockets,  any scheme is allowed.
>#
>#  - polkit: use PolicyKit to authenticate. This is only suitable
>#            for use on the UNIX sockets. The default policy will
>#            require a user to supply their own password to gain

># message received from the client.  If keepalive_interval is set to
># -1, libvirtd will never send keepalive requests; however clients
