Chapter 3. Upgrading from 4.0 to Red Hat Virtualization 4.2

Procedure

1. On the Red Hat Virtualization Manager machine, check if updated packages are available:

   # engine-upgrade-check

2. Update the setup packages:

   # yum update ovirt\*setup\*

3. Update the Red Hat Virtualization Manager. The engine-setup script prompts you with some configuration questions, then stops the ovirt-engine service, downloads and installs the updated packages, backs up and updates the database, performs post-installation configuration, and starts the ovirt-engine service.

   # engine-setup

   Note

   The engine-setup script is also used during the Red Hat Virtualization Manager installation process, and it stores the configuration values supplied. During an update, the stored values are displayed when previewing the configuration, and may not be up to date if engine-config was used to update configuration after installation. For example, if engine-config was used to update SANWipeAfterDelete to true after installation, engine-setup will output "Default SAN wipe after delete: False" in the configuration preview. However, the updated values will not be overwritten by engine-setup.

   Important

   The update process may take some time; allow time for the update process to complete and do not stop the process once initiated.

4. Update the base operating system and any optional packages installed on the Manager:

   # yum update

   Important

   If any kernel packages were updated, reboot the host to complete the update.
