Chapter 14. Upgrading a Self-Hosted Engine from 4.2 to Red Hat Virtualization 4.3

Upgrading a self-hosted engine environment from version 4.2 to 4.3 involves the following steps:

14.1. Prerequisites

  • Plan for any necessary virtual machine downtime. After you update the clusters' compatibility versions during the upgrade, a new hardware configuration is automatically applied to each virtual machine once it reboots. You must reboot any running or suspended virtual machines as soon as possible to apply the configuration changes.
  • Ensure your environment meets the requirements for Red Hat Virtualization 4.3. For a complete list of prerequisites, see the Planning and Prerequisites Guide.
