openstack-neutron bug fix advisory

Type/Severity

Bug Fix Advisory

Topic

Updated OpenStack Networking packages that resolve various issues are now
available for Red Hat OpenStack Platform 8.0 (Liberty) for RHEL 7.

Description

Red Hat OpenStack Platform provides the facilities for building 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 openstack-neutron component:

• Previously, if all controller nodes restarted at the same time, it would cause all amqp (rabbitmq) servers to also restart. This caused the connection between Neutron agents and the amqp servers to appear to hang until timed-out, while the time-out length is linear (60 seconds, then 120, then 240... limited at 600), preventing agents from receiving any events until the timeout expires. With this update, the timeout mechanism in the specific event that tries to connect between the agents and the neutron-server was changed to always be 60 seconds. Now, if the connection hangs because of a restart of all controller nodes, the agents recover quicker (up to 60 seconds after the controllers fully start again). (BZ#1365378)

Solution

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

Red Hat OpenStack Platform 8 runs on Red Hat Enterprise Linux 7.2.

The Red Hat OpenStack Platform 8 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 8, including which channels need to be enabled and disabled.
