Hello together,

I'm proceeding with this installation and I'm facing a strange problem with openvswitch on the controller node which has been reported here too:

https://ask.openstack.org/en/question/10228/neutron-ovs-error-on-controller/

If I do a ovs-vsctl show, I'm getting:

[root@controller ~]# ovs-vsctl show

2014-03-16T04:40:26Z|00001|reconnect|WARN|unix:/var/run/openvswitch/db.sock: connection attempt failed (No such file or directory)

ovs-vsctl: unix:/var/run/openvswitch/db.sock: database connection failed (No such file or directory)

And in /var/log/neutron/openvswitch-agent.log I can see:

2014-03-15 23:22:37.296 3084 INFO neutron.common.config [-] Logging enabled!

2014-03-15 23:22:37.296 3084 ERROR neutron.plugins.openvswitch.agent.ovs_neutron_agent [-] Tunneling cannot be enabled without a valid local_ip. Agent terminated!

It seems that on the controller the ovs neutron agent doesn't like my "local_ip".

But on the compute and network node ovs-vsctl show works:

[root@neutron ~]# ovs-vsctl show

And here is my ifconfig on the controller node:

Any ideas?

Hi there. It's also worth mentioning that we are actively working on
improving the OpenStack installation process with Foreman, including
adding a better UI and some workflow components to stage
deployments. Watch this list for details as they emerge.
