+Note: Disable Security Groups in OpenStack ML2 Setup
+****************************************************
+
+Please note that Security Groups feature has been disabled automatically through ``local.conf`` configuration file
+during the setup procedure of OpenStack in both `Controller Node <./2-ipv6-configguide-os-controller.html>`_
+and `Compute Node <./3-ipv6-configguide-os-compute.html>`_ using ``devstack``.
+
+If you are installing OpenStack using a different installer (i.e. not with ``devstack``), please make sure
+that Security Groups are disabled in the setup.
+
+**Please refer to

+for the notes in** ``Section 2.4``, **steps** ``OS-NATIVE-SEC-1`` **through** ``OS-NATIVE-SEC-3``.
