+from the new systemVM template version.
+
+.. note::
+
+   Restarting system VMs can be done in different ways. You can use script
+   "cloudstack-sysvmadm" which is provided with CloudStack, or do a manual restart of system VMs
+   or do it by using third-party tools such as Ansible.
+   Below we are giving instructions for using the "cloudstack-sysvmadm" script.

 is used by the cloudstack-sysvmadm script at the end of the upgrade
 procedure. For information about how to set this parameter, see :ref:`configuration parameters <configuration-parameters>`
