I want to set up a private cloud using 3 desktop machines using opennebula (or openstack) cloud platform. One will be the front-end and 2 nodes.
But i don't have idea how can i configure/connect these machines (in terms of hardware) together to build that cloud environment.
I would like to know how can i realize this configuration to obtain/build my own private cloud and what are the steps?
I guess you haven't prefer the official documentation of the thing you are asking to implement.
You can simply follow the clear steps from https://docs.opennebula.org/5.6/intro_release_notes/concepts_terminology/intro.html#step-1-choose-your-hypervisor
I hope you have got your answer and prefer to ask any doubts if that deals some serious implementation!
