Chapter 7. Adding a Host to the Red Hat Virtualization Manager

Adding a host to your Red Hat Virtualization environment can take some time, as the following steps are completed by the platform: virtualization checks, installation of packages, and creation of a bridge. Use the details pane to monitor the process as the host and the Manager establish a connection.

Adding a Host to the Red Hat Virtualization Manager

  1. From the Administration Portal, click ComputeHosts.
  2. Click New.
  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 Manager 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. Click the Advanced Parameters button to expand the advanced host settings.

    • Optionally disable automatic firewall configuration.
    • Optionally add a host SSH fingerprint to increase security. You can add it manually, or fetch it automatically.
  7. Optionally configure power management, where the host has a supported power management card. For information on power management configuration, see Host Power Management Settings Explained in the Administration Guide.
  8. Click OK.

The new host displays in the list of hosts with a status of Installing, and you can view the progress of the installation in the details pane. After a brief delay the host status changes to Up.


Keep the environment up-to-date. See for more information. Since bug fixes for known issues are frequently released, Red Hat recommends using scheduled tasks to update the hosts and the Manager.
