Comment 4 for bug 1629133

A little bit more info. This is breaking general ipv4 connectivity in OSIC for our test nodes because we don't get public IPv4 addresses there so any IPv4 connections to the internet are NATed with the local address living in 10.0.0.0/8. This breaks the route for that then no more IPv4 connectivity.

Also I would very strongly prefer that we address this without making any changes to devstack-gate. If we fix this with changes to devstack-gate then that means that people using this must run devstack-gate rather than just devstack to have a working devstack installation.
