Using Virtualbox create a new virtual machine: Choose “I will install the operating system later.” Use the CentOS7 minimal install x86_64 iso image file. The idea for this lab was taken from my Winter 2015 Final Exam, it is a great project that I know you will love. Linux can be a server, a gateway router, a proxy, a transparent bridge you name it, and using virtualization I have the flexibility to test things from my laptop workstation. From a networker’s perspective there is so much you can do with Linux, so many servers and free tools to play with.
