  For the steps to reproduce this, do the following:

  1. Install Ubuntu 13.10, install git/maven/openvswitch-switch/pip related packages and so on, whatever is required for devstack and ODL. Do *not* install mysql-server - allow devstack to do that for you, else you will run into a lot of issues with mysql. Create two such VMs, one intended to run as ctrl and the other as compute.
  2. Install and run ODL with Openflow 1.3 as per the instructions given on the ODL wiki.
  3. Run devstack to bring up both control and compute nodes. Attempt to spawn VMs, and see if you hit the above exception.

  For instructions on setting up devstack with ODL, look at Kyle's
