Configuring Vagrant Multiple Machines

 centos7 base box was created as per the steps at http://anandbitra.blogspot.com/2015/01/creating-centos-7-vagrant-base-box.html

You can also add a box from publicly available catalog of Vagrant boxes at https://atlas.hashicorp.com/boxes/search

Modify Vagrantfile to configure CPUs, memory, network and mount shared folders. The below configuration will work for Virtualbox.

Open Git Bash
$ cd centos7-vagrant
$ vagrant init anandbitra/centos-7.1
$ vi Vagrantfile

Comment all the lines and add the below lines.
