Virtualization is a process of creating virtual OS, Hardware and Network, is one of the most sought technology of these days. We will be discussing on how to install and configure virtualization in detail.
Lets prepare CentOS Minimal server to host virtual machines that is accessible over HTTP by installing following packages.
Install VirtualBox prerequisite packages
