I tested http://docs.openstack.org/developer/devstack/guides/neutron.html#using-neutron-with-a-single-interface and stack.sh failed.
I used exactly the configuration described in that doc section, with only a link-local IPv6 address on the one network interface, but with a couple of changes to local.conf. One is that I added "IP_VERSION=4" to avoid any attempt to configure Neutron to use IPv6. The other is that I added a few lines to improve the logging --- mainly making the logs go to files (which I will attach to this bug).
I used Ubuntu 14.04.3, fully updated. That means kernel 3.19.0-42-generic.
I downloaded openvswitch-2.4.0.tar.gz and built the Debian packages for OpenVswitch according to the instruction contained therein. For OVS installation: I eschewed the kernel module I just built, instead relying on what is shipped with Linux 3.19, and I installed the openvswitch-switch and openvswitch-common debian packages I had just built.
When I ran stack.sh, it aborted with problems configuring br-ex. In the attached archive, under home/mspreitz/devstack/, you will find a file named typescript, produced by `script`, which shows some of the state before I started stack.sh (as well as a typescript of running stack.sh). You will also find postmortem.log, showing some of the state right after stack.sh aborted. Additionally there is net-recovery.log, showing how I recovered to a working network configuration --- hopefully this gives further clues to what went wrong in stack.sh. You will see that what I did is to change the state of the br-ex link to UP and then add the appropriate route through br-ex (although at least part of that command was unnecessary). You will also find that opt/stack/logs/ has all the logs that stack.sh normally produces.
I suspect the problem centers around the br-ex link not being "up". But that's only a slightly informed guess.
For easy reference, here is the end of stack.sh.log:
