<div dir="ltr"><div><div><div><div>Hi,<br><br></div>I spent a few hours deploying LBaaS V2 to my devstack instance and tested it with the Tempest api test developed a couple of week ago during the Neutron code sprint. This is a list of the findings so far:<br>
<br></div>1) POST operations on loadbalancers, healthmonitors and listeners work fine<br><br></div>2) POST operations on pools don't work. The api throws a 500 with the following message: "NeutronError": "Request Failed: internal server error while processing your request.". The error can be reproduced with the following operation:<br>
