Public bug reported:

Hello!

I've already had successful deployment on Pike (3 control node + several compute nodes): 
 - ML2 plugin - openvswitch
 - default tunnel type - vxlan
 - dvr is enabled

Instances were started, running, migrating without errors. 
Everything was fine until I've upgraded to Queens... I've use same neutron configuration files and encountered the following error:

It happens every time I try to launch instance. No matter, internal or external (vlan provider) network, result is the same.

So my question is 'What I'm doing wrong?' May be I missed something in
Queens config samples, or encountered the huge bug, or what?..
