Hi,

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:

1) POST operations on loadbalancers, healthmonitors and listeners work fine

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:

POST /lbaas/pools
{"pool": {"name": "miguelito", "protocol": "HTTP", "lb_algorithm":
"ROUND_ROBIN", "healthmonitor_id": "98311c52-9ba5-4d1c-beb7-a8200edf3c40"}}

The Neutron server log shows the following error:

Over the next few days I will report api testing results for healthmonitors
and listeners. I will also test pools and memebers as soon as the problems
with pools POST reported above is fixed

Cheers
