This is not the default for deployments, except for the ignorant people
using DevStack for deployment and they have already self-selected for
failure by doing that in the first place.

Honestly, I don't give a rat's a$$ about the migrations.  But I do care
about the knowledge required to mentally shift from nova-net to neutron.
And we have failed there.  DevStack has totally failed there to make
Neutron usable without having to learn far too much to just get a dev cloud.

The complaint was about DevStack using LB as its default.  I DO NOT want
the overhead of OVS on my development VMs when I am not doing any
network-related work. I am not alone here.

Simple things MUST be simple to do.
