Hi YAMAMOTO (and other midokura folks), I spotted unit tests in the branch are failing due to upper constraints not applied. So I backported the fix as: https://review.openstack.org/#/c/392698/ Sadly, it does not pass because tempest for midonet v2 fails: http://logs.openstack.org/98/392698/1/check/gate-tempest-dsvm-networking-midonet-v2/9494c9c/logs/devstacklog.txt.gz#_2016-11-02_15_10_13_949 It looks like midonet SDN controller misbehaving. Would you mind taking it from there and propose the needed patches to pass the gate for the patch? Thanks, Ihar
