3 Major Changes in SUSE Cloud 4

SUSE Cloud 4 is a major update to SUSE Cloud and comes with many new features, improvements and bug fixes. The following list highlights a selection of the major changes:

  • OpenStack has been updated to the 2014.1 (Icehouse) release (, and the deployment framework has been updated accordingly to support new features. On top of the new features that come by default with this new version, here are some notable features that have been added:

    • Multiple block storage backends, with different drivers if needed, can now be defined and used at the same time in Block Storage (Cinder).

    • The driver for the FUJITSU Storage ETERNUS DX series and the VMware VMDK driver have been added for Block Storage (Cinder).

    • Load-Balancing-as-a-Service (LBaaS) and Firewall-as-a-Service (FWaaS) are enabled for OpenStack Networking (Neutron).

    • The openstack command line interface is distributed and can be used by the cloud users in replacement of the command line interfaces specific to each OpenStack component (such as nova, keystone, glance, cinder, neutron, etc.). It provides a unified and more user-friendly interface to interact with OpenStack.

    • Newer versions of the APIs can be enabled: Compute (Nova) API v3 and Volume (Cinder) API v2. Note that Identity (Keystone) API v3 and Image (Glance) API v2 are also available.

    • Database-as-a-Service for OpenStack (Trove) is included as technology preview.

  • The OpenStack Integration Test Suite (Tempest) can be deployed through a Crowbar barclamp to validate the OpenStack deployment. This is provided for convenience purposes only and is not supported.

  • The OpenStack infrastructure can be deployed in a highly available way, to provide a higher Service Level Agreement (SLA). This covers the controller side of OpenStack, but doesn't cover the hypervisor nodes. This feature was already provided through a maintenance update to SUSE Cloud 3 and is fully integrated in SUSE Cloud 4.

  • The distributed storage system Ceph has been updated to the 0.80 (Firefly) release. It is not a technology preview anymore, and is now supported. The Ceph Object Gateway can also be deployed.

4 Technology Previews

Technology previews are packages, stacks, or features delivered by SUSE. These features are not supported. They may be functionally incomplete, unstable or in other ways not suitable for production use. They are mainly included for customer convenience and give customers a chance to test new technologies within an enterprise environment.

Whether a technology preview will be moved to a fully supported package later, depends on customer and market feedback. A technology preview does not automatically result in support at a later point in time. Technology previews could be dropped at any time and SUSE is not committed to provide a technology preview later in the product cycle.

Please, give your SUSE representative feedback, including your experience and use case.

SUSE Cloud 4 ships with the following technology previews:

  • Database-as-a-Service for OpenStack (Trove), and the respective Crowbar barclamp for deploying it.

  • EqualLogic driver for Cinder.

  • MongoDB, as database for Ceilometer.

5 Upgrading to SUSE Cloud 4

Upgrading to SUSE Cloud 4 is supported from SUSE Cloud 3, with the latest updates applied. If running a previous version, please first upgrade to SUSE Cloud 3. If running without the updates, please first apply them.

The upgrade process is a multi-step process that is semi-automated, thanks to the suse-cloud-upgrade utility that will guide you through the various steps. As the OpenStack infrastructure will be turned off for the upgrade, it is important to suspend all running instances prior to the upgrade so they can be properly restored after the upgrade. It is also highly recommended to perform a backup of both the Administration Server and the OpenStack data.

The complete upgrade process is documented in the Deployment Guide, which can be found online at

6 Documentation and Other Information

  • Read the READMEs on the CDs.

  • Get the detailed changelog information about a particular package from the RPM (with filename <FILENAME>):

    rpm --changelog -qp <FILENAME>.rpm
  • Check the ChangeLog file in the top level of CD1 for a chronological log of all changes made to the updated packages.

  • Find more information in the docu directory of CD1 of the SUSE Cloud 4 CDs. This directory includes PDF versions of the SUSE Cloud documentation.

  • contains additional or updated documentation for SUSE Cloud.

  • Visit for the latest product news from SUSE and for additional information on the source code of SUSE Linux Enterprise products.

7 Known Issues

  • Upgrade from a SUSE Cloud 3 deployment with HA is not functional at release time. This will be addressed with an online update.

  • No pre-built image for Heat or Trove are shipped with SUSE Cloud; cloud administrators are responsible for creating such images.

  • The trove update command fails with a HTTP 404 error. This will be addressed with an online update.

  • No 32-bit support; currently x86_64 architecture is required for all components.

  • Live migration of instances only work between homogeneous compute nodes: the nodes need to have the same CPU features.

  • Removal of barclamps from a node do not necessarily shut down associated services or remove associated packages. This means that you may well run into problem if moving barclamp roles from one node to another. Manual remediation may be required in these cases.
