Hi oslo all, Currently devstack master relies on 1.8.1 release due to requirements frozen (>=1.8.0 < 1.9.0), however, ZeroMQ driver is able to run on 1.9.0 release. The result is that you cannot deploy ZeroMQ driver using devstack master now due to some incompatibility between oslo.messaging 1.8.1 and devstack master source. So I try to backport 4 recent reviews [1-4] to stable/kilo to make sure it is working. I'll appreciate allowing these backports and make them into 1.8.2.
