Don’t be scared by the clumsily-worded Select Start-up Disk screen, because this just means select your installation ISO image, then watch your new OS go into its normal installation screens.

You’ll be returned to the main VirtualBox control panel where you can click the Start button. On the File Location and Size screen allocate enough space to hold your installation, plus a good buffer for growth. A fixed-size is suppose to deliver a little faster performance, at the cost of tying up unused storage space. On the next screen you have to choose a fixed or dynamically-allocated hard drive file. In the next two screens create a new virtual hard drive in VDI (VirtualBox disk image) format. This memory will not be available to my host system (Kubuntu) when CentOS is running. If you’re installing a headless server with no graphics it’s enough, but if you want graphics then give it more, just as though you were doing a standalone installation. Virtualbox, for whatever reason, recommends 512 MB, which is not enough for most installations. Just fill out the information and click Next. Fire up VirtualBox, and click the pretty blue New button.

First download an installation ISO image in the usual way. Installing a guest operating system is easy as can be. I’m going to skip over installation because it’s easy– just use your favorite Linux package manager. Chances are you do, and you can easily check with this command: $ egrep -o '(vmx|svm)' /proc/cpuinfo If you do not have this you can still use Virtualbox, but it will be a lot slower. One other thing you must have, and that is CPU support for virtualization. In other words, a perfect system for stuffing a bunch of virtual machines into with horsepower and storage to burn.

A small gaggle of 2TB SATA 6 hard disks.

16 big ole gigabytes of dual-channel DDR3 1600 memory.

Intel i7-4770K CPU 3.50GHz with four physical and eight, count ’em, eight virtual cores.

My upgraded hotrod Intel system has these specs: You’ll especially want a lot of RAM and disk storage. The more powerful your system the better, because you are running multiple operating systems at the same time. Not that installing Linux is very exciting as it’s been dead-easy for years. Not “loosing”.) It’s a fast and easy way to test distros and capture installation screenshots. I use VirtualBox to keep multiple instances of development sandboxes, so I can freely experiment and blow things up without worrying about losing anything.

In this fun era of powerful desktop PC hardware, cheap virtualization opens a vast world of possibilities. Virtualization is a big deal on servers for boosting hardware efficiency, and it is one of the foundation blocks of cloud technologies. Then you can run any of these operating systems on VirtualBox as guests in virtual machines.
