Hi,

I appreciate the help. In neutron-server I have the following service providers enabled:

service_provider = LOADBALANCERV2:Haproxy:neutron_lbaas.drivers.haproxy.plugin_driver.HaproxyOnHostPluginDriver:default
service_provider = LOADBALANCERV2:Octavia:neutron_lbaas.drivers.octavia.driver.OctaviaDriver

With Octavia provider L7 policy works fine. With haproxy (agent provider) I receive the error below.

On the haproxy agent I have the following setting (however, the neutron-server throws that error and not even sends any request to agent):

interface_driver = neutron.agent.linux.interface.OVSInterfaceDriver
device_driver = neutron_lbaas.drivers.haproxy.namespace_driver.HaproxyNSDriver

Hello Mihaela,



It seems that you are referring to that part of code https://github.com/openstack/neutron-lbaas/blob/mitaka-eol/neutron_lbaas/drivers/driver_base.py#L36

I found that document for Mitaka https://docs.openstack.org/mitaka/networking-guide/config-lbaas.html

It might be related to incorrectly configured driver for LBaaS (or indeed not implemented driver for L7 policy for specific driver).

Questions:

* What do you have configured in neutron configuration in section [service_providers]?
* Which driver do you want to use?

Example line

service_provider = LOADBALANCERV2:Haproxy:neutron_lbaas.drivers.haproxy.plugin_driver.HaproxyOnHostPluginDriver:default

Cheers,
Paweł

Hello,

Does the agent implementation of LBaaSv2 support L7 policies? I am testing with Mitaka version and I get "Not Implemented Error".
