Topic

Updated OpenStack Networking packages that resolve various issues are now
available for Red Hat OpenStack Platform 16.1 (Train) for Red Hat
Enterprise Linux (RHEL) 8.2.

Description

Red Hat OpenStack Platform provides the facilities for building, deploying
and monitoring a private or public infrastructure-as-a-service (IaaS) cloud
running on commonly available physical hardware. This advisory includes
packages for:

  • OpenStack Networking service

OpenStack Networking (neutron) is a virtual network service for OpenStack.
Just as OpenStack Compute (nova) provides an API to dynamically request and
configure virtual servers, OpenStack Networking provides an API to
dynamically request and configure virtual networks. These networks connect
'interfaces' from other OpenStack services (e.g. virtual NICs from Compute
VMs). The OpenStack Networking API supports extensions to provide advanced
network capabilities (e.g. QoS, ACLs, network monitoring, etc.)

Changes to the python-networking-ovn component:

  • In this release, you can use SR-IOV in an ML2/OVN deployment with native OVN DHCP. SR-IOV in an ML2/OVN deployment no longer requires the Networking service (neutron) DHCP agent.

+
When virtual machines boot on hypervisors that support SR-IOV NICs, the OVN controllers on the controller or network nodes can reply to the DHCP, internal DNS, and IPv6 router solicitation requests from the virtual machine.
+
This feature was available as a technology preview in RHOSP 16.1.0. Now it is a supported feature.
+
The following limitations apply to the feature in this release:

  • All external ports are scheduled on a single gateway node because there is only one HA Chassis Group for all of the ports.
  • Routing on VLAN tenant network does not work with SR-IOV because the external ports are not co-located with the logical router’s gateway ports. See https://bugs.launchpad.net/neutron/+bug/1875852. (BZ#1666684)
  • This update includes support for both TCP and UDP protocols on the same load-balancer listener for OVN Provider driver. (BZ#1703958)

Solution

Before applying this update, ensure all previously released errata relevant
to your system have been applied.

Red Hat OpenStack Platform 16.1 runs on RHEL 8.2.

The Red Hat OpenStack Platform 16.1 Release Notes contain the following:

  • An explanation of the way in which the provided components interact to

form a working cloud computing environment.

  • Technology Previews, Recommended Practices, and Known Issues.
  • The channels required for Red Hat OpenStack Platform 16.1, including

which channels need to be enabled and disabled.

The Release Notes are available at:
https://access.redhat.com/documentation/en-us/red-hat-openstack-platform/

This update is available through 'yum update' on systems registered through
Red Hat Subscription Manager. For more information about Red Hat
Subscription Manager, see:
