This project is a reference for myself to quickly create a fresh Oracle VM with just the right packages to use for testing and learning purposes. (specifically for my LFCS courses.
This project utilizes the CentOS 7 Minimal distribution including developer packages.

After creating countless VM's in Oracle VirtualBox manually, I decided it was time to save myself some cycles and work more efficiently. This is my process and the .sh files I used to execute after the preliminary configurations.
