Tried all sorts of different configurations to get this to bind. I think this is right, ovs sees the physical ports and i can create external flat networks with the bridges. When the vm comes up an ip is allocated for a second then disappears. If i create an internal network, an ip will be allocated. I have checked all over. Attached logs, neutron config and interface configs to my git:

https://github.com/mrbriancollins/wtf... 10.1.13.251 - controller, network 10.1.13.11-14 - compute

logs are taken in debug mode from startup. I have no idea why this won't bind a port.....

Should be misconfiguration berwenn Neutron Server on Controller && OVS agent on Compute
I would expect corresponding logs to report ERROR. Check rabbitmq-server status on Controlle

Found in logs after debug:

remapped bridges, ports are now attaching.

added file foo to my repo which is a grep of session id 415b6af1-e47a-4ac6-912f-aeddd9d5d1b1 through all the servers.... this session id is me trying to raise a defaut cirros , no storage, one network, smallest config.

I have asked you to provide the logs. Is my English good enough to understand what I need you to do ?

Looks as a typo
Post CIDR of yours mgmt nenwork.

layout is as so:

 mgnt network = 10.1.13.0/24
controller = 10.1.13.251
network = 10.1.13.251

compute = 10.1.13.11, 10.1.13.12, 10.1.13.13, 10.1.13.14

i have 3 networks to use for openstack:
10.1.10.0/24 = br10
10.1.15.0/24 = br15
50.205.206.32/27 = br999

its odd too because it pulls an ip address then the ip address disappears and the build fails.... it can pull a floating ip address as well but i haven't tested connectivity

bcollins ( 2016-08-31 09:01:56 -0600 )edit

I would expect you to check logs :-

1. /var/log/neutron/neutron-server.log on Controller
2. /var/log/neutron/neutron-ovs-agent.log on Compute
