Appendix D. Upgrading to Red Hat Virtualization Manager 4.2 with ovirt-fast-forward-upgrade

If you have Red Hat Virtualization 4.0 or later installed, you can upgrade the Manager to the latest version with the ovirt-fast-forward-upgrade tool. ovirt-fast-forward-upgrade detects the current version of the Manager and checks for available upgrades. If an upgrade is available, the tool upgrades the Manager to the next major version, and continues to upgrade the Manager until the latest version is installed.


ovirt-fast-forward-upgrade upgrades the Manager. See Section A.4, “Manually Updating Hosts” to upgrade the hosts.

Upgrading with ovirt-fast-forward-upgrade

  1. Install the ovirt-fast-forward-upgrade tool:

    # yum install ovirt-fast-forward-upgrade
  2. Run the following command to upgrade the Manager, while creating a backup of the current version:

    # ovirt-fast-forward-upgrade --backup --backup-dir=/backup

    Red Hat recommends using the --backup and --backup-dir options to create a backup of the current Manager. If a backup directory is not specified, the backup is saved in /tmp.

    The --backup option is a wrapper for the engine-backup tool and is equivalent to running the following command:

    # engine-backup --scope=all --mode=backup --file=file_name --log=log_file_name

    To restore your backup, run engine-backup in restore mode:

    # engine-backup --mode=restore

    See Backing Up and Restoring the Red Hat Virtualization Manager in the Administration Guide for details.

    Alternatively, to upgrade without creating a backup, run the following command:

    # ovirt-fast-forward-upgrade
  3. If there are errors, check the log: /var/log/ovirt-engine/ovirt-fast-forward-upgrade.log.
