Scenario - VMware NSX Plugin

Introduction

This document covers the steps to integrate the VMware NSX plugin with OpenStack Ansible.

Warning

Currently, only NSX-T Policy API is supported.

Please follow these steps:

• Configure Neutron to use the NSX plugin

Prerequisites

1. The deployment environment is configured according to OSA best practices such as cloning OSA software and bootstrapping Ansible. See OpenStack-Ansible Install Guide.

2. NSX-T has been deployed per its installation guide and compute nodes have been properly configured as transport nodes. See NSX-T Data Center Installation Guide <https://docs.vmware.com/en/VMware-NSX-T-Data-Center/3.0/installation/GUID-3E0C4CEC-D593-4395-84C4-150CD6285963.htm> _.

Configure Neutron to use the NSX plugin

Copy the neutron environment overrides to /etc/openstack_deploy/env.d/neutron.yml and disable agent creation, since it is not needed.

neutron_agents_container:
  belongs_to:
    - network_containers
  contains: { }

Copy the nova environment overrides to /etc/openstack_deploy/env.d/nova.yml and disable neutron agent creation, since it is not needed.

container_skel:
  nova_api_container:
    belongs_to:
      - compute-infra_containers
      - os-infra_containers
    contains:
      - nova_api_metadata
      - nova_api_os_compute
      - nova_conductor
      - nova_scheduler
      - nova_console
  nova_compute_container:
    belongs_to:
      - compute_containers
      - kvm-compute_containers
      - qemu-compute_containers
    contains:
      - nova_compute
    properties:
      is_metal: true

Set the following required variables in your /etc/openstack_deploy/user_variables.yml

neutron_plugin_type: vmware.nsx
nova_network_type: nsx
nsx_api_password: <password>
nsx_api_managers:
  - nsx-manager-01
  - nsx-manager-02
  - nsx-manager-03

Optionally specify additional parameters using overrides

neutron_nsx_conf_ini_overrides:
  nsx_p:
    default_tier0_router: my-tier0-router
    default_overlay_tz: my-overlay-tz
    default_vlan_tz: my-vlan-tz
    metadata_proxy: my-metadata-proxy-profile
    dhcp_profile: my-dhcp-profile

Warning

If NSX has defined more than one tier 0, overlay/vlan tz, metadata proxy, or dhcp profile, then you must explicitly define those using conf overrides. Neutron will fail to start if these are not defined in those conditions.

Installation

After the environment has been configured as detailed above, start the OpenStack deployment as listed in the OpenStack-Ansible Install Guide.
