Red Hat Client Registration
You can register Red Hat Enterprise Linux clients to your Uyuni Server using either the Red Hat content delivery network (CDN), or Red Hat update infrastructure (RHUI). The method and details varies depending on the operating system of the client.
Before you start, ensure that the client has the date and time synchronized correctly with the Uyuni Server.
You must also have created an activation key. For more information about creating activation keys, see Activation Keys.
