New installation of Kilo, 3 nodes, controller, network, compute. All CentOS 7. Followed the doc, fairly straight forward. This is the first instance I've tried to launch, I have not gotten any instance to successfully launch. Running as admin, and I haven't come across any other erorrs as I try to describe the various resources (image, nic, security group, etc) to try to isolate the problem. I have debugging on in all the components, and can't find any other errors in the other logs. I'm stumped.

edit - I see the same error as majiclamp when doing 'nova endpoints'. I get a list of endpoints for each service, one for each interface (internal, admin,public), all in RegionOne, but at the start of each service (glance, neutron,keystone, nova), I get

WARNING: nova has no endpoint in ! Available endpoints for this service:
