Description of problem:
Attempting to create a server in a deployment with 3 controllers using ODL as networking backed fails with the mentioned
Version-Release number of selected component (if applicable):
16.0.0-0.20170818142923.716a4c8.el7ost.noarch
How reproducible:
100 %
Steps to Reproduce:
1. Get a virtual deployment of OSP12 with ODL and 3 controllers
2. Attempt to start a server
Actual results:
The newly created server ends in "ERROR" status
openstack server shows:

Expected results:
server starts
Additional info:
The hypervisor on which it is executed has 128 GB RAM and 32 cores, computes are VMs, with 16 GB RAM and 2 cpus.
Just a quick note:
This is a weird one, it's possible it was caused by tempest changing something in the environment/it might have appeared in a cluster after a while that it was running/some packages got update as I am no longer able to reproduce this on a clean environment
