Problems getting to the Horizon GUI

Recent changes in DevStack networking has affected several services. Neutron is now the default network tool instead of Nova. As a result the software definied networking we use in our lab environment does not work properly with the changes to the back end software. We are working on a fix and will report back here as well as update the material once the fix is found and tested.
Thank you.

Thanks, could you please post a notice when you have it working properly?
DevStack changes. A lot. And not always with advanced warning. If you monitor the various component groups you can keep track of what is going to happen, but it tends to demand a lot of time. As a result it was difficult to know the affect of a change from default Nova networking to Neutron networking would have on your environment. It will take some time to find a best solution, for the interum period please use a Liberty release of DevStack.
Replace references (there are a few of them) to the devstack git repository with this one:
SERVICE_PASSWORD=SERVICE-secret SERVICE_TOKEN=ALongStringUsuallyHere #REMOVED BARBICAN LINE enable_service rabbit mysql key
There may be several references to the repository, for example when installing the second node. Please use the same branch for each.
