Hi, From my previous 3K+ nodes 6+ regions OpenStack operations experience in Yandex, I found useless to have Cinder and Neutron services in cross-region manner.
BTW, nova-neutron cross-region interactions are still legitimate use case: you may utilize one neutron for many nova regions. -- With best regards, Vladimir Eremin, Fuel Deployment Engineer, Mirantis, Inc. > On Mar 4, 2016, at 7:43 AM, Dolph Mathews <dolph.math...@gmail.com> wrote: > > Unless someone on the operations side wants to speak up and defend > cross-region nova-cinder or nova-neutron interactions as being a legitimate > use case, I'd be in favor of a single region identifier. > > However, both of these configuration blocks should ultimately be used to > configure keystoneauth, so I would be in favor of whatever solution > simplifies configuration for keystoneauth. > > On Tue, Mar 1, 2016 at 10:01 PM, Kai Qiang Wu <wk...@cn.ibm.com > <mailto:wk...@cn.ibm.com>> wrote: > Hi All, > > > Right now, we found that nova.conf have many places for region_name > configuration.
