Hi, haproxy can't start because of its listening ports on vip conflicting with openstack services' listening ports on 0.0.0.0. I opened a bug about it: https://bugs.launchpad.net/openstack-manuals/+bug/1649902 Could anyone help to check this? Or any workaround about it such as change haproxy's listening ports or change openstack services' listening port to be not 0.0.0.0? Thanks a lot! Regards QingFeng Hao(Johnny)
