Open Stack

Going through the log , I saw the following error on o-hm

2016-11-03 03:31:06.441 19560 ERROR octavia.controller.worker.controller_worker     request_ids=request_ids)
2016-11-03 03:31:06.441 19560 ERROR octavia.controller.worker.controller_worker BadRequest: Unrecognized attribute(s) 'dns_name'
2016-11-03 03:31:06.441 19560 ERROR octavia.controller.worker.controller_worker Neutron server returns request_ids: ['req-1daed46e-ce79-471c-a0af-6d86d191eeb2']

And it seemed that I need to upgrade my neutron client.  While I am planning to do it, could somebody please send me the document on how this vip is supposed to plug into the lbaas vm and what the failover is about ?

Thanks!
Wanjing

Subject: [openstack-dev] [Neutron][neutron-lbaas][octavia] Not be able to ping loadbalancer ip

So I bring up octavia using devstack (stable/mitaka).   I created a loadbalander and a listener(not create member yet) and start to look at how things are connected to each other.  I can ssh to amphora vm and I do see a haproxy is up with front end point to my listener.  I tried to ping (from dhcp namespace) to the loadbalancer ip, and ping could not go through.  I am wondering how packet is supposed to reach this amphora vm.  I can see that the vm is launched on both network(lb_mgmt network and my vipnet), but I don't see any nic associated with my vipnet:

And it seemed that amphora created a port from the vipnet for its vrrp_ip, but now sure how it is used and how it is supposed to help packet to reach loadbalancer ip

It will be great if somebody can help on this, especially on network side.

Thanks
