RHBA-2017:2992 - Bug Fix Advisory

Topic

Updated Installation utility packages that resolve various issues are now
available for Red Hat Enterprise Linux OpenStack Platform 6.0 (Juno) for
RHEL 7.

Description

Red Hat Enterprise Linux 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:

• Installation utility ("PackStack").

PackStack is a command-line utility for deploying OpenStack on existing
servers over an SSH connection. Deployment options are provided either
interactively, using the command line, or non-interactively by means of a
text file containing a set of preconfigured values for OpenStack
parameters.

PackStack is suitable for deploying the following types of configurations:

• Single-node proof-of-concept installations, where all controller services

and your virtual machines run on a single physical host. This is referred
to as an all-in-one install.

• Proof-of-concept installations, where there is a single controller node

and multiple compute nodes. This is similar to the all-in-one install
above, except you may use one or more additional hardware nodes for running
virtual machines.

Changes to the openstack-puppet-modules component:

• Previously, some binary Python modules used by Horizon were compiled with a flag that requires them to use the simplified GIL state API. Since mod_wsgi uses sub-interpreters and the simplified GIL state API is not reentrant, it results in the mod_wsgi locking up. Consequently the dashboard is unavailable. With this update, the mod_wsgi configuration was changed, forcing mod_wsgi to use the main interpreter instead of sub-interpreters. As a result, mod_wsgi works correctly. (BZ#1485890)
