https://wiki.openstack.org/wiki/NeutronDevstack worked for me.

However, I'm pretty sure it's only a single node all in one setup. At least,
I created only one VM to run it on and I don't think DevStack has created
multiple nested VMs inside of the one I create to run DevStack. I haven't
gotten around to figuring out how to setup a full multi-node DevStack
setup with separate compute nodes and network nodes and GRE/VXLAN tunnels.

There are multi-node instructions on that wiki page but I haven't tried
following them. If someone has a Vagrant file that creates a full multi-
node Neutron devstack complete with GRE/VXLAN tunnels it would be great
if they could add it to that wiki page.
