6. Select a keyboard layout from the Keyboard screen and click Done.

7. Specify the installation location from the Installation Destination screen.

   Important
   • Red Hat strongly recommends using the Automatically configure partitioning option.
   • All disks are selected by default, so deselect disks that you do not want to use as installation locations.
   • At-rest encryption is not supported. Do not enable encryption.

   • Red Hat recommends increasing the size of /var/log to at least 15GB to provide sufficient space for the additional logging requirements of Red Hat Gluster Storage.

     Follow the instructions in Growing a logical volume using the Web Console to increase the size of this partition after installing the operating system.

   Click Done.

11. Set a root password and, optionally, create an additional user while Red Hat Virtualization Host installs.

    Warning

    Red Hat strongly recommends not creating untrusted users on Red Hat Virtualization Host, as this can lead to exploitation of local security vulnerabilities.

12. Click Reboot to complete the installation.

    Note

    When Red Hat Virtualization Host restarts, nodectl check performs a health check on the host and displays the result when you log in on the command line. The message node status: OK or node status: DEGRADED indicates the health status. Run nodectl check to get more information. The service is enabled by default.
