RHBA-2017:0201 - Bug Fix Advisory

Topic

Updated OpenStack Networking packages that resolve various issues are now
available for Red Hat OpenStack Platform 10.0 (Newton) for RHEL 7.

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.)

With this release, the following components have been re-based:

• openstack-neutron to 9.1.1 (BZ#1410937)
• python-networking-odl t0 3.2.0 (BZ#1411834)

This update also applies several fixes and enhancements, including one
that helps ensure connectivity between switch and external controller.
(BZ#1394865)

The OpenStack Networking service supports two modes for
ovsdb_interface, namely: 'vsctl' and 'native'. In Red Hat OpenStack
Platform 9, the default mode was 'vsctl'. In the last version, the
default changed to 'native'.

In 'native' mode, when using Red Hat OpenStack Platform 10 with
external controllers (such as ODL), the dhcp-agent overrode the OVS
manager on the switch to loopback IP (ie. the default value of
ovsdb_connection). As a result, the connection between the existing
controller and the switch was lost.

With this release, OpenStack Networking no longer overrides the
manager on the switch. Rather, a new manager is added as necessary.
This way, the connection between the switch and external controller
stays intact.

Solution

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

Red Hat OpenStack Platform 10 runs on Red Hat Enterprise Linux 7.3.

The Red Hat OpenStack Platform 10 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 10, including which

channels need to be enabled and disabled.
