I think this is fundamentally due to the problem identified at step 4 where the pod and service IP ranges overlap.

That is addressed by bug https://bugzilla.redhat.com/show_bug.cgi?id=1473858

Once that issue is addressed we can work out if there are other problems or if that is the root cause of everything.

The MTU was not set correctly for the interface (based on the underlying OpenStack networking configuration).

This was messing the etcd traffic up and making all sorts of things misbehave.
