Unfortunately, there are two versions of VirtualBox: one is freeware and one is free software. Lastly, there is also a generic installer for GNU/Linux on the download page. If you run Ubuntu or MEPIS, you can install Automatix, which will install VirtualBox for you. The SimplyMEPIS site has a guide to installing VirtualBox here. There are binaries on the download site for Windows, Ubuntu 6.06-7.04, Debian 3.1-4.0, openSuSE 10.2, Mandriva 2007.1, Red Hat Enterprise 4, and the Univention Corporate Server 1.3-2. Getting VirtualBox varies from platform to platform. The next version, coming soon, will include support for running the pre-built VMWare appliances. And on certain guests, you can install VirtualBox Guest Additions, which lets you share files and more between the guest and the host. It runs Windows, OS/2, GNU/Linux, BSD, Netware, Solaris, and L4 guests. It is cross-platform (runs on Windows and GNU/Linux, with an Intel Mac version in beta). Besides, it just can’t do some basic things that the others can (like pause a virtual machine, for example). Therefore, it is extremely complicated to create a new virtual machine with it. The problem with QEMU is that it is completely command-line (there are GUIs made for it, but they never worked for me). The other one (called a server) will make machines, but isn't as fast as the professional version. One (called a player) runs pre-built operating systems (known as appliances). That leaves us with VMWare, QEMU, and VirtualBox. Parallels is commercial at US$49.99 for Windows and GNU/Linux. Right now, there are four big ones: Parallels, VMWare, QEMU, and VirtualBox.
Introductionįirst, choose which virtualization tool to use. If you want to get rid of the virtualized (also known as the guest) operating system, just delete the virtual hard disk from the real (host) computer’s hard drive. A virtual machine creates a virtual hard drive as well as a virtual computer, so you can install and run it from within another operating system. After all, what if you mess up? What if you end up corrupting your hard drive so badly that you need to format it to get rid of GNU/Linux? The solution is to use virtualization technology.
