         * Autostart won't work for session mode, so we assume
         * user started it manually on the remote host in this
         * case.
         *
         * If we have a 'session' URI without explicit socket,
         * we can just assume the use of virt-ssh-helper, since
         * logic for constructing socket paths relies on env
         * envs whose values have no guarantee of matching those
         * on the remote host. It was explicitly blocked with an
         * error check before virt-ssh-helper was introduced.
         *
         * For 'system' URIs, we need to try virt-ssh-helper but
