Chapter 3. Attaching a Host-based Subscription to Hypervisors

download PDF

Use this procedure to attach a host-based subscription, such as Red Hat Enterprise Linux for Virtual Datacenters, to hypervisors that are already registered to Red Hat Satellite.

To register a new hypervisor, ensure your host activation key includes a host-based subscription, then see Registering Hosts in the Managing Hosts guide. You must register a hypervisor before configuring virt-who to query it.


  • Import a Subscription Manifest that includes a host-based subscription into Satellite Server.
  • Ensure you have sufficient entitlements for the host-based subscription to cover all of the hypervisors you plan to use.


  1. In the Satellite web UI, navigate to Hosts > Content Hosts.
  2. In the Content Hosts list, select the check box next to the name of each hypervisor you want to attach the subscription to.
  3. From the Select Action list, select Manage Subscriptions.
  4. In the Content Host Bulk Subscriptions window, select a host-based subscription, then click Add Selected.

For CLI Users

  1. On Satellite Server, list the available subscriptions to find the host-based subscription’s ID:

    # hammer subscription list \
    --organization-id organization_id
  2. Attach the host-based subscription to a hypervisor:

    # hammer host subscription attach \
    --host host_name \
    --subscription-id subscription_id

    Repeat these steps for each hypervisor you plan to use.
