I'm sure that you may need more methods, as this was POC code, so we only put the minimum required.
It was based on FOLSOM, so if you're working with a more updated version then the interfaces might have changed.
I did that a few months ago, so I currently don't have an environment in which I can test that. However, from the errors it looks like it is an environmental issue, as it didn't even get to the driver (it says it failed to schedule the cinder command).
