+++ This bug was initially created as a clone of Bug #1736786 +++
enable_telemetry appears to be enabled by default and setting enable_telemetry = false doesn't appear to disable telemetry at all ... I've setted it to enable_telemetry = false , set the messaging driver to noop and re-ran undercloud install ... it reverted the driver to messaging !
