+      You are not building wheels while running role against multiple hosts.
+      This might result in DOS-ing OpenDev infrustructure servers.
+      In order to proceed, please ensure that you have repo servers
+      for selected OS version and architecture.
+      If you want to avoid building wheel on purpose, ensure that you run
+      playbook in serial manner.
+      In case of causing unreasonable load on the opendev.org git servers,
+      your access may be blocked to protect other users and the OpenDev CI
+      infrastructure which are reliant on this service.
