This section describes the supported configurations and drivers, and subscription details necessary for NFV.

3.1. Registering and enabling repositories

To install Red Hat OpenStack Platform, you must register Red Hat OpenStack Platform director using the Red Hat Subscription Manager, and enable the required repositories. For more information, see Preparing for director installation.

Procedure

  1. Register your system with the Content Delivery Network, and enter your Customer Portal user name and password when prompted.

    [stack@director ~]$ sudo subscription-manager register
  2. Determine the entitlement Pool ID for Red Hat OpenStack Platform director. For example:

    [stack@director ~]$ sudo subscription-manager list --available --all --matches="Red Hat OpenStack"
    
    Subscription Name:   Name of SKU
    Provides:            Red Hat Single Sign-On
                         Red Hat Enterprise Linux Workstation
                         Red Hat CloudForms
                         Red Hat OpenStack
                         Red Hat Software Collections (for RHEL Workstation)
                         Red Hat Virtualization
    SKU:                 SKU-Number
    Contract:            Contract-Number
    Pool ID:             {Pool-ID}-123456
    Provides Management: Yes
    Available:           1
    Suggested:           1
    Service Level:       Support-level
    Service Type:        Service-Type
    Subscription Type:   Sub-type
    Ends:                End-date
    System Type:         Physical
  3. Include the Pool ID value in the following command to attach the Red Hat OpenStack Platform 15 entitlement.

    [stack@director ~]$ sudo subscription-manager attach --pool={Pool-ID}-123456
  4. Disable the default repositories.

    subscription-manager repos --disable=*
  5. Enable the required repositories for Red Hat OpenStack Platform with NFV.

    $ sudo subscription-manager repos --enable=rhel-8-for-x86_64-baseos-rpms \
    --enable=rhel-8-for-x86_64-appstream-rpms \
    --enable=rhel-8-for-x86_64-highavailability-rpms \
    --enable=ansible-2.8-for-rhel-8-x86_64-rpms \
    --enable=openstack-15-for-rhel-8-x86_64-rpms \
    --enable=rhel-8-for-x86_64-nfv-rpms \
    --enable=advanced-virt-for-rhel-8-x86_64-rpms \
    --enable=fast-datapath-for-rhel-8-x86_64-rpms
  6. Perform an update on your system for the latest base system packages.

    [stack@director ~]$ sudo dnf update -y
    [stack@director ~]$ sudo reboot

To register your overcloud nodes, see Ansible Based Registration.

3.2. Supported configurations for NFV deployments

Red Hat OpenStack Platform (RHOSP) supports the following NFV deployments using director:

  • Single root I/O virtualization (SR-IOV)
  • Open vSwitch with Data Plane Development Kit (OVS-DPDK)

Additionally, you can deploy Red Hat OpenStack Platform with any of the following features:

Note

Red Hat’s embedded OpenDaylight SDN solution was deprecated in RHOSP 14. Red Hat continues to provide support and bug fixes for OpenDaylight, with all support ending with the RHOSP 13 lifecycle on June 27, 2021.

RHOSP 15 NFV deployments with Open Virtual Network (OVN) as the default SDN solution are unsupported. Use the following steps to deploy RHOSP with the OVS mechanism driver:

Procedure

  1. Set the neutron_driver parameter to null in the containers-prepare-parameter.yaml file.

    parameter_defaults:
      ContainerImagePrepare:
      - push_destination: true
        set:
         neutron_driver: openvswitch
         ...
  2. Include the neutron-ovs.yaml environment file in the /usr/share/openstack-tripleo-heat-templates/environments/services directory with your deployment script.

    TEMPLATES=/usr/share/openstack-tripleo-heat-templates
    
    openstack overcloud deploy --templates \
    -e ${TEMPLATES}/environments/network-environment.yaml \
    -e ${TEMPLATES}/environments/network-isolation.yaml \
    -e ${TEMPLATES}/environments/host-config-and-reboot.yaml \
    -e ${TEMPLATES}/environments/services/neutron-ovs.yaml \
    -e ${TEMPLATES}/environments/services/neutron-ovs-dpdk.yaml \
    -e ${TEMPLATES}/environments/services/neutron-sriov.yaml \
    -e /home/stack/containers-prepare-parameter.yaml
