Re: [Rdo-list] Current status of RDO Liberty CBS Repos and Bug "neutron-openvswitch-agent is crashing with "invalid literal for int() with base 10" error "



  I've recently have built system per Howto https://github.com/beekhof/osp-ha-deploy/blob/master/HA-keepalived.md
( and one more time want to thank Javier Pena for this document ).
In particular , I followed instructions for Neutron:-  
    https://github.com/beekhof/osp-ha-deploy/blob/master/keepalived/neutron-config.md
which installed neutron/plugins/ml2/drivers/openvswitch/agent/ovs_neutron_agent.py unpatched
I also ran :-
    # neutron-db-manage --config-file /etc/neutron/neutron.conf  \
       --config-file /etc/neutron/plugin.ini upgrade head
on Controller 1
   Finally , system running HAProxy/Keepalived 3 node Controller (RDO Liberty) and one  Compute node works fine
shows up :-

Yes, RDO Liberty is affected (Delorean Liberty is not).

Please RDO folks advice: should we backport the patch or wait till rebase?
