I followed the manual to install kilo:

This is all working fine, thanks for the good documentation. I am able to start a VM through openstack.

Now I am trying to add the vpnaas to the OpenStack implementation and this is where I am getting stuck.

On the network node I installed the 'neutron-vpn-agent'. I than edited the following files: /etc/neutron/vpn_agent.ini:

interface_driver = neutron.agent.linux.interface.OVSInterfaceDriver
external_network_bridge =
router_delete_namespaces = True


/etc/neutron/neutron.conf: Added vpnaas to the service_plugins

After that I restarted the neutron-vpn-agent and verified that there are no errors in the logfile at (/var/log/neutron/neutron-vpn-agent.log)

Then on the controller node I tried: neutron vpn-service-list

But that failed with: 404 Resource not found.

I obviously am missing something but I cannot find out what. Also the documentation on installing vpnaas is not available, searching with google didn't give me a suitable answer either...

So how do I need to proceed, what am I missing?

Any reason for having external_network_bridge undeclared?

Do you have any ext_br?

According to the documentation at (To configure the Layer-3 (L3) agent):

The external_network_bridge option intentionally lacks a value to enable multiple external networks on a single agent.

And yes I do have an external br, created also according the documentation.

How did You install 'neutron-vpn-agent' on network node ? I have three node architecture running on Ubuntu 14.0.4 and if I try to install 'neutron-vpn-agent' by package manager I receive notice "neutron-vpn-agent : Conflicts: neutron-l3-agent but 1:2015.1.1-0ubuntu2~cloud2 is installed".

After searching I found out what I was doing wrong.

First of all there was not a neutron_vpnaas.conf file. After I created it with the following contents:


I edited this file on the controller node. The network node itself was configured correctly and I could see the vpn agent running and responding.

The interface started working and I can create ikepolicies, ipsecpolicies and vpn services.
