Once you've upgraded the packages on your management servers, you'll
need to restart the system VMs. Ensure that the admin port is set to
8096 by using the "integration.api.port" global parameter. This port
is used by the cloud-sysvmadm script at the end of the upgrade
procedure. For information about how to set this parameter, see :ref:`configuration parameters <configuration-parameters>`
Changing this parameter will require management server restart. Also
make sure port 8096 is open in your local host firewall to do this.
Please note that the integration.api.port (8096) is unauthenticated
port and must not be open for public access.

There is a script that will do this for you, all you need to do is
run the script and supply the IP address for your MySQL instance and
your MySQL credentials:

.. parsed-literal::

   # nohup cloudstack-sysvmadm -d IPaddress -u cloud -p password -a > sysvm.log 2>&1 &

You can monitor the log for progress. The process of restarting the
system VMs can take an hour or more.

.. parsed-literal::

   # tail -f sysvm.log

The output to ``sysvm.log`` will look something like this:

.. parsed-literal::

   Stopping and starting 1 secondary storage vm(s)...
   Done stopping and starting secondary storage vm(s)
   Stopping and starting 1 console proxy vm(s)...
   Done stopping and starting console proxy vm(s).
   Stopping and starting 4 running routing vm(s)...
   Done restarting router(s).
