The value of use_neutron is set to false (instead of true) when neutron is used. The fix is quite straightforward, the wrong line is: use_neutron => ($sahara_cfg_controller_host == 'y') into packstack/puppet/templates/sahara.pp Found on RDO package: openstack-packstack-2014.2-0.13.dev1395.gaabe0a2.fc22.noarch and of course current git master (713b745e0efbaaba5695055f6125464f72afcee1).
The value of use_neutron is now correctly set according the availability of Neutron (True if requested and installed from packstack, False otherwise). openstack-packstack-2014.2-0.17.dev1462.gbb05296.el7ost.noarch openstack-packstack-puppet-2014.2-0.17.dev1462.gbb05296.el7ost.noarch
