Hi, While testing nova test cases we are able to make the Nova online successfully. However controller-0 is unable to communicate with compute-0(nova) and not allowing to add data interface on controller-0. Due to this issue we are not able to execute the remaining test cases for the compute (nova) and network can be run from controller-0.we also observe sub-functions are missing from the controller-0. We are following below link 1.https://wiki.openstack.org/wiki/StarlingX/stx.2018.10_Testplan_Instructions 2.https://wiki.openstack.org/wiki/StarlingX/Installation_Guide_Virtual_Environ... running command: "$system host-show 1 | grep subfunctions" does not return - "| subfunctions | controller,compute" Thank you, Rajesh Jha The information contained in this e-mail and any accompanying documents may contain information that is confidential or otherwise protected from disclosure.
