=====Setting up RHEL7 Hostnames=====
This is relevant if you are using templates and you need to set the hostname of the new VM

There is a file at 

  /etc/hostname
  
That is used to set the name.

There is also a command **hostnamectl** that is used to manage it

To change the hostname run following command

  hostnamectl set-hostname hostname
  
and restart the server
