Applies to SUSE OpenStack Cloud 9

13 Overview

To ensure that your environment meets the requirements of the cloud model you choose, see the check list in Chapter 14, Pre-Installation Checklist.

After you have decided on a configuration to choose for your cloud and you have gone through the pre-installation steps, you will have two options for installation:

  • You can use a graphical user interface (GUI) that runs in your Web browser.

  • You can install via the command line that gives you the flexibility and full control of SUSE OpenStack Cloud 9.

Using the GUI

You should use the GUI if:

  • You are not planning to deploy availability zones or use L3 segmentation in your initial deployment.

  • You are satisfied with the tuned SUSE-default OpenStack configuration.

Instructions for GUI installation are in Chapter 21, Installing with the Install UI.


Reconfiguring your cloud can only be done via the command line. The GUI installer is for initial installation only.

Using the Command Line

You should use the command line if:

  • You are installing a complex or large-scale cloud.

  • You need to use availability zones or the server groups functionality of the cloud model. For more information, see the Chapter 5, Input Model.

  • You want to customize the cloud configuration beyond the tuned defaults that SUSE provides out of the box.

  • You need more extensive customizations than are possible using the GUI.

Instructions for installing via the command line are in Chapter 24, Installing Mid-scale and Entry-scale KVM.


Ardana is an open-source project and a generalized lifecycle management framework. Cloud Lifecycle Manager is based on Ardana, and delivers the lifecycle management functionality required by SUSE OpenStack Cloud 9. Due to this relationship, some Cloud Lifecycle Manager commands refer to Ardana.
