-Running the playbook
-^^^^^^^^^^^^^^^^^^^^

-The playbook defined in the :ref:`previous step<NVIDIA OS Configuration>`
-should be run after `kayobe overcloud host configure` has completed. This will
-ensure the host has been fully bootstrapped. With default settings, internet
-connectivity is required to download `MIG Partition Editor for NVIDIA GPUs`. If
-this is not desirable, you can override the one of the following variables
-(depending on host OS):

-Run the playbook that you defined earlier:
-
-.. code-block:: shell
-
-  kayobe playbook run $KAYOBE_CONFIG_PATH/ansible/host-configure.yml
-
-Note: This will reboot the hosts on first run.
-
-The playbook may be added as a hook in ``$KAYOBE_CONFIG_PATH/hooks/overcloud-host-configure/post.d``; this will
-ensure you do not forget to run it when hosts are enrolled in the future.
