Public bug reported:

ryu >= 4.1 is broken for Python 2.7 environments - the following commit requires ovs>=2.6.0.dev0 for all environments:
https://github.com/osrg/ryu/commit/b8cb2d22aab1b761e9e2de2df1a93cc60ed60dfa

Contrastingly, upper-constraints prevents ovs>2.5.0 in Python 2.7 environments:
https://git.openstack.org/cgit/openstack/requirements/tree/upper-constraints.txt#n229

This is showing up as a breakage in the XenServer Neutron CI (currently
on internal testing before commenting externally):
pkg_resources.ContextualVersionConflict: (ovs 2.5.0
(/usr/local/lib/python2.7/dist-packages),
Requirement.parse('ovs>=2.6.0.dev0'), set(['ryu']))
