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
- From the Administration Portal, click Compute → Hosts.
- Click New.
- Use the drop-down list to select the Data Center and Host Cluster for the new host.
- Enter the Name and the Address of the new host. The standard SSH port, port 22, is auto-filled in the SSH Port field.
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.
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.
- 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.
- 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 https://access.redhat.com/articles/2974891 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.
