The instance creation was working until calico configured on controller and compute. Ubuntu 16 and Centos releases are booting up successfully. As known ubuntu began to work with netplan since 18 and all latest releases. Not sure the issue with cloud init or the order or timing of booting process which relates to getting IP in time and properly.
