Setting up a shared hosting network

Guys, i have bought a dedicated server and have installed virtualmin on it. I have created a private server on the left space to make a shared hosting. Probably less than 10 users.
I have a question, how do you set it up ? Like does WHMCS does all the work or i should set up the users host manually ??

If this is not the correct section, please change it.
