Well, I just tried this out with a much shorter URI and it worked. I think it might have to do with the length. So this might actually be an issue with oslo.config's URI type http://docs.openstack.org/developer/oslo.config/types.html#oslo_config.types.URI and this is the constructor that's used for that option in nova http://docs.openstack.org/developer/oslo.config/opts.html#oslo_config.cfg.URIOpt
