I've submitted a devstack change to fix this, the review is listed below for those interested. I'm unclear how this was approved into Quantum given that it pretty much broke everyone using devstack with the OVS plugin, I would have expected a matching devstack patch to make devstack work as well. Regardless, the change to devstack is relatively minor, but will thus make devstack only work with the latest version of Quantum, given this config file change. Since I don't believe devstack works with older versions of anything, I believe this to be ok.

So, devstack is not updating oslo.config for both Fedora and Ubuntu
for me. See here for Fedora 18:

[kmestery at km-dhcp-64-188 ~]$ sudo pip-python list|grep oslo.config
oslo.config (1.1.0)
[kmestery at km-dhcp-64-188 ~]$ 

And here for Ubuntu 12.04:

kmestery at ucs-3:~$ pip freeze | grep oslo.config
oslo.config==1.1.0
kmestery at ucs-3:~$ 

So should devstack be doing this? And even if it did, I think this
will break the way Robert is deploying. I think this change may
need some more thought it appears.

Thanks,
Kyle
