A Red Hat training course is available for Red Hat Virtualization

3.2. Upgrading to Red Hat Virtualization Manager 4.1

The following procedure outlines the process for upgrading Red Hat Virtualization Manager 4.0 to Red Hat Virtualization Manager 4.1 in a standard deployment. See Upgrading a Self-Hosted Engine Environment in the Self-Hosted Engine Guide for more information about upgrading the Manager in a Self-hosted Engine deployment.
This procedure assumes that the system on which the Manager is installed is subscribed to the entitlements for receiving Red Hat Virtualization 4.0 packages.

Important

If the upgrade fails, the engine-setup command will attempt to roll your Red Hat Virtualization Manager installation back to its previous state. For this reason, the repositories required by Red Hat Virtualization 4.0 must not be removed until after the upgrade is complete. If the upgrade fails, detailed instructions display that explain how to restore your installation.

Important

Ensure that you are running the latest minor version of Red Hat Virtualization Manager 4.0 before upgrading by running engine-upgrade-check. See Section 2.1, “Updating the Red Hat Virtualization Manager” for more information.

Procedure 3.1. Upgrading to Red Hat Virtualization Manager 4.1

  1. Enable the Red Hat Virtualization Manager 4.1 and Red Hat Virtualization Tools repositories: 
    # subscription-manager repos --enable=rhel-7-server-rhv-4.1-rpms \
    --enable=rhel-7-server-rhv-4-tools-rpms \
    --enable=jb-eap-7.1-for-rhel-7-server-rpms
  2. Update the setup packages: 
    # yum update ovirt\*setup\*
  3. Run the following command and follow the prompts to upgrade the Red Hat Virtualization Manager: 
    # engine-setup
  4. Remove or disable the Red Hat Virtualization Manager 4.0 repository to ensure the system does not use any Red Hat Virtualization Manager 4.0 packages: 
    # subscription-manager repos --disable=rhel-7-server-rhv-4.0-rpms --enable=jb-eap-7.0-for-rhel-7-server-rpms
  5. Update the base operating system: 
    # yum update

    Important

    If any kernel packages were updated, reboot the system to complete the update.
You must now change the cluster and data center compatibility version to 4.1. See Chapter 4, Post-Upgrade Tasks.
