Create cluster in one system

Please, describe the problem here and provide additional information below (if applicable) …
While I’m creating cluster in one system through “my_system_ip:port”, virtual OS image is not uploading,it’s not showing any error also. I want to create node and front end clustering in one system. Can anybody please tell me how to do ? Thanks.

Versions of the related components and OS (frontend, hypervisors, VMs): ubuntu 16.04, KVM, opennebula 5.6

Steps to reproduce: clustering between front end and node in standalone mood

Current results: not showing any message

Expected results: clustering between front end and node in standalone mood
