9.3. Subscribing to the Required Entitlements

To be used as a hypervisor host, make sure the Red Hat Enterprise Linux host meets the hardware requirements listed in Chapter 2. The host must also be registered and subscribed to a number of entitlements using Subscription Manager. Follow this procedure to register with the Content Delivery Network and attach the Red Hat Enterprise Linux Server and Red Hat Enterprise Virtualization entitlements to the host.

Procedure 9.1. Subscribing to Required Entitlements using Subscription Manager

  1. Register your system with the Content Delivery Network, entering your Customer Portal Username and Password when prompted:
    # subscription-manager register
  2. Find the Red Hat Enterprise Linux Server and Red Hat Enterprise Virtualization subscription pools and note down the pool IDs.
    # subscription-manager list --available
  3. Use the pool IDs located in the previous step to attach the entitlements to the system:
    # subscription-manager attach --pool=poolid

    Note

    To find out what subscriptions are currently attached, run:
    # subscription-manager list --consumed
    To list all enabled repositories, run:
    # yum repolist
  4. Ensure all hosts remain on Red Hat Entrprise Linux 7.3:
    subscription-manager release --set=7.3
  5. Disable all existing repositories:
    # subscription-manager repos --disable=*
  6. Enable the required repositories.

    Important

    Red Hat Enterprise Virtualization 3.x has reached End Of Life (EOL). Users with Extended Lifecycle Support (ELS) must use the repositories in https://access.redhat.com/solutions/3194482 to keep the environment up and running.
    If you are installing Red Hat Enterprise Linux 7 hosts, little endian on IBM POWER8 hardware, enable the following repositories instead:
    # subscription-manager repos --enable=rhel-7-server-rhev-mgmt-agent-for-power-le-rpms
    # subscription-manager repos --enable=rhel-7-for-power-le-rpms
    

    Important

    Red Hat Enterprise Linux 7 hosts, little endian on IBM POWER8 is not part of the Extended Lifecycle Support (ELS) offering.
  7. Ensure that all packages currently installed are up to date:
    # yum update
Once you have subscribed the host to the required entitlements, proceed to the next section to attach your host to your Red Hat Enterprise Virtualization environment.
