Thanks Thomas. Or perhaps we need a fix to Quantum itself to create the link with the proper MAC address to begin with rather than changing it in a second step?

With the above error, I wonder if the Quantum Quickstart ever fully worked at all on either RHOS or RDO Grizzly? Terry, how did you work around the above issue when testing on RHOS?
