Red Hat OpenStack Platform 16

Red Hat Infrastructure Migration Solution 


Red Hat ® OpenStack Platform delivers an integrated foundation to create, deploy, and scale a secure and reliable public or private OpenStack cloud.


Multi-cell deployments using Cells v2

Red Hat OpenStack Platform compute is now powered by cells by default. You can configure larger deployments to use multiple cells, each with specific compute nodes and a database.  Global services control placement and fail-safe operations, and the separation into cells helps to improve security and process isolation

Colocation of pinned and floating instances on a single host

Schedule instances with pinned CPUs (hw:cpu_policy=dedicated) on the same host as instances that use floating CPUs (hw:cpu_policy=shared). It's no longer necessary to use host aggregates to ensure these instance types run on separate hosts.

Live migration for instances with SR-IOV

With OSP 16, you can live-migrate instances configured with SR-IOV (single-root I/O virtualization). For direct mode SR-IOV intefaces, live migration will incur some network downtime as the interface is detached and re-attached.  This is not an issue for indirect mode SR-IOV interfaces.

Live migration of pinned instances

This NUMA-aware live migration feature allows you to live migrate instances with a NUMA topology.

Bandwidth-aware scheduling

Create instances that request a guaranteed minimum bandwidth using a quality-of-service (QoS) policy.  The compute scheduling service selects a host for the instance that satisifies the guaranteed minimum bandwidth request.

ACL support for load-balancing service (Octavia)

Red Hat OpenStack Platform's load-balancing service (Octavia) now supports VIP access control lists (ACLs) to limit a listener's incoming traffic to a set of allowed source IP addresses (CIDRs).

OVN internal API TLS/SSL/support

Red Hat OpenStack Platform now supports the encryption of internal API traffic for OVN using transport layer security (TLS).

OVN deployment over IPv6

Red Hat OpenStack Platform also supports the deployment of OVN over an IPv6 network.

Simultaneously attach a volume to multiple instances

With RHOSP 16, you can simultaneously attach a volume to multiple instances both for block storage service (cinder) and for compute, if the back end driver supports it.

Deploy glance-cache on far-edge nodes

Deploy image service (glance) caching at the edge to improve the boot time for instances and decrease the bandwidth usage between core and edge sites. It will also preclude using compute nodes to fetch images from the core site in medium to large edge sites.

Red Hat Ceph Storage Upgrade

To maintain compatibility with Red Hat Enterprise Linux 8, Red Hat OpenStack Platform 16.0 director deploys Red Hat Ceph Storage 4 Beta.  You can use Red Hat OpenStack Platform 16.0 running on RHEL8 to connect to a pre-existing external Red Hat Ceph Storage 3 cluster running on RHEL7.

Get Started with Red Hat OpenStack Platform

For a basic installation, you'll need:

System Requirements

Your hardware should meet the system requirements.

A Network Connection

You'll need a public network connection to register and download software.

Installer Image

Installation Media

Burn the ISO image to DVD or create a bootable USB medium, which will be used to install the Hypervisor.

Install Red Hat OpenStack Platform 16

  1. 1

    Install RHEL

    Perform a minimal installation for RHEL 8 on a physical system. See getting started for Red Hat Enterprise Linux 8 for more details.

  2. 2


    Register the system via Red Hat Subscription Management and confirm that an OpenStack subscription is attached.

    # subscription-manager register

    # subscription-manager list --consumed

    If an OpenStack subscription is not attached immediately, see the documentation for manually attaching subscriptions.

  3. 3

    Plan your installation

  4. 4

    Prepare for director installation

    • create directories for templates and images
    • set the system hostname
    • install director packages
    • generate the container images file
  5. 5

    Install director (the undercloud)

    • configure the director
    • obtain overcloud node images
    • set a nameserver
    • complete undercloud configuration
  6. 6

    Configure and create the overcloud


OpenShift on OpenStack

OpenShift on OpenStack: a seamless integration

In this briefing, Red Hat's Ramon Acedo Rodriguez presents the strategy, vision, and current state of affairs for containers within Red Hat OpenStack Platform.  His session covers the roles containers play in OpenStack, what Red Hat is focusing on, what they have already delivered to users, and what will likely be the future of the infrastructure and tenant layers.

The future is open (hybrid cloud)

OpenStack and the Enterprise

NTT Comware creates cloud service with Red Had OpenStack Platform

NTT Comware wanted to create a cloud service offering, SmartCloud DevaaS® 2.0, to provide a DevOps development environment for its users. By creating a self-service development portal based on Red Hat OpenStack Platform, NTT Comware cut operating costs by 30 percent. In addition, they will offer operational environments based on container orchestrations using Red Hat OpenShift Container Platform.
