This guide explains how to upgrade the following environments to oVirt 4.3:

  • Standalone manager, local database: Both the Data Warehouse database and the Engine database are installed on the Engine.

  • Standalone manager, remote database: Either the Data Warehouse database or the Engine database, or both, are on a separate machine.

  • Self-hosted engine, local database: Both the Data Warehouse database and the Engine database are installed on the Engine.

Plan any necessary downtime in advance. 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 VMs as soon as possible to apply the configuration changes.

Select the appropriate instructions for your environment from the following table. If your Engine and host versions differ (if you have previously upgraded the Engine but not the hosts), follow the instructions that match the Engine’s version.
