can't get networking-odl LBaaS driver to work

[Martin Banszel]

Hello,

I am trying to get the **neutron-lbaas** work with **odl lbaas driver**. My setup is devstack stable/liberty, a host running ODL beryllium 0.4.1, on the host two virtualboxes one for the controller and one for the compute node.

**My question is: is that implemented in networking-odl? Did it ever work?**

When I tried to create a load balancer:

    neutron lbaas-loadbalancer-create --name lb1 39a1eae8-8091-4e8a-9f27-5cac3064b179

I get:

    Request Failed: internal server error while processing your request.

Looking into the q-svc.log I can see that there is attribute exception:

Looking into
https://github.com/openstack/neutron-lbaas/blob/stable/liberty/neutron_lbaas/drivers/driver_base.py#L44
and comparing to the constructor of the ODL LBaaS driver class:
https://github.com/openstack/networking-odl/blob/stable/liberty/networking_odl/lbaas/driver_v2.py#L32

it seems to me that the memebrs in ODL driver have wrong names. I changed them to match the neutron-lbaas code, so from:

     self._loadbalancer = ODLLoadBalancerManager(self.client)
        self._listener = ODLListenerManager(self.client)
        self._pool = ODLPoolManager(self.client)
        self._member = ODLMemberManager(self.client)
        self._healthmonitor = ODLHealthMonitorManager(self.client)

I made a change to:

      self.load_balancer = ODLLoadBalancerManager(self.client)
        self.listener = ODLListenerManager(self.client)
        self.pool = ODLPoolManager(self.client)
        self.member = ODLMemberManager(self.client)
        self.healthmonitor = ODLHealthMonitorManager(self.client)

After this change, I got a little bit further. After trying to create the loadbalancer I get this error:

    [stack@control networking-odl]$ neutron lbaas-loadbalancer-create --name lb1 39a1eae8-8091-4e8a-9f27-5cac3064b179
    An error happened in the driver

When playing with wget I figured out that the URL seems to be wrong and wget http://20.99.0.1:8087/controller/nb/v2/neutron/lbaas/loadbalancers
actually returns some answer (other than 404) -- I get a list of exsiting loadbalancers. So it seems that '/' is missing in the url in the code.

When I added the slash to the url, I get this error:

Looking into the code, it posts an empty request:
https://github.com/openstack/networking-odl/blob/stable/liberty/networking_odl/lbaas/driver_v2.py#L68

    @log_helpers.log_method_call
    def create(self, context, obj):
        self.client.sendjson('post', self.url_path, None)

but according to the wiki (https://wiki.opendaylight.org/view/OVSDB_Integration:LBaaS#Testing)
it seems that there should be a body.

Also the v1 driver seems to be all stubs. (https://github.com/openstack/networking-odl/blob/stable/liberty/networking_odl/lbaas/driver_v1.py)

Thank you.
