Install Additional Self-Hosted Engine Hosts

You add self-hosted engine hosts the same way as a regular host, with an additional step to deploy the host as a self-hosted engine host. The shared storage domain is automatically detected and the host can be used as a failover host to host the Engine virtual machine when required. You can also add regular hosts to a self-hosted engine environment, but they cannot be used to host the Engine virtual machine.

Important:

Before you begin, refer to Prepare a KVM Host.

To install an additional self-hosted engine host, complete the following steps.

1. In the Administration Portal, go to Compute and click Hosts.

2. Click New.

   For information on additional host settings, see the Admin Guide in the latest upstream oVirt Documentation.

3. Use the drop-down list to select the Data Center and Host Cluster for the new host.

4. Enter the Name and the Address of the new host. The standard SSH port, port 22, is auto-filled in the SSH Port field.

5. Select an authentication method to use for the engine to access the host.

   • Enter the root user’s password to use password authentication.

   • Alternatively, copy the key displayed in the SSH PublicKey field to /root/.ssh/authorized_keys on the host to use public key authentication.

6. Optionally, configure power management, where the host has a supported power management card. For information, see Configure Power Management and Fencing for Host.

7. Click the Hosted Engine sub-tab.

8. Select the Deploy radio button.

9. Click OK.
