Comment 24 for bug 1110807

@Spatialist attached patch solves the problem on my end. Could you test it and confirm it solves the problem on your end as well and doesn't produce any regression?

On Ubuntu, db_base_plugin_v2.py is located in /usr/lib/python2.7/dist-packages/quantum/db. Make sure you locate it withinyour distribution. Patch it:

sudo patch -p0 -i lp-1110807.patch
sudo restart quantum-server

and then try reproducing the problem

If everything works out, I'll submit it for review.

Thanks
