Open Stack

That sounds reasonable. I wonder if the RYU folk can chime in here.

Subject: Re: [openstack-dev] [neutron][dynamic routing] RYU Breaks lower constraints

I think this is caused by the recent pip change and pip no longer cannot import pip from code. The right solution seems to bump the minimum version of ryu.

Thought?
