Comment 33 for bug 1625305

I was able to reproduce the issue on master devstack (d7e7dd451aca77a19f5c101f8367c18cdbcac904
, multinode environment with DVR, 1 all-in-1 controller (dvr_snat), 2 computes (dvr)).

Steps to reproduce:
1. create a network/subnet, boot a vm.
2. try to restart openvswitch-agent

Upon adding some printf logging it seems that sg- port, qr- port of the tenant network and vm port all have local_vlan tag set to the same value. So second attempt to remove it fails with KeyError.

Here are the logs - http://paste.openstack.org/show/616060/
