Open Stack

Hello Fabrice,

  I think the easiest way would be to set the affinity for each
controller/infrastructure host using 'rsyslog_container: 0' as seen in the
following section of the install guide:
http://docs.openstack.org/developer/openstack-ansible/install-guide-revised
-draft/configure-initial.html#affinity

  Next, you should add your actual logging hosts to your
openstack_user_config as seen here:
https://github.com/openstack/openstack-ansible/blob/master/etc/openstack_de
ploy/openstack_user_config.yml.aio#L122-L124

  Be sure to comment out the rsyslog-install.yml line of
setup-infrastructure.yml, and be sure that you make any necessary
modifications to the openstack-ansible-rsyslog_client role.  Modifications
may not be necessary, depending on your needs, and you may be able to
specify certain variables in user_variables.yml to achieve the desired
results.

  As always, make sure you test these modifications in a non-production
environment to ensure you achieve the desired results.
