What does VirtualBox Do?
A virtual machine is an application or operating system that runs within another operating system. The purpose of a virtual machine varies — I use virtual machines to test the guides and software I write about in Windows XP and Vista. Other people use virtual machines to test the software they create, let a virus loose within an isolated environment, or because they have so much memory in their machine and they don’t know what to do with it. VirtualBox, owned by Sun Micro Systems, is a free and open source virtualization product.
In this review, I’ll talk about the program while showing you what it is capable of.
When setting up the software, I recommend including everything that comes with it. Unlike VMWare workstation, which takes up over 700 MB on your hard drive, VirtualBox only takes up around 85 MB.
VirtualBox requires new drivers which interface your physical hardware with and the virtualized environment it creates. Thus, it is important to install these drivers when prompted.
Create a Virtual Machine
Note: You will need either the installation disc or an ISO image of the operating system you wish to install.
After installation, you can open the program and click on New to create a new virtual machine.
The new virtual machine wizard opens, click next.
Give a descriptive name to the operating system you’re about to install and select the operating system and version from the drop-down list.
Select he amount of memory you’d like to use for the operating system; VirtualBox will give recommendations on how much memory you should use. I recommend using at least the amount of memory recommended by VirtualBox and at most half of total physical memory you have in your machine.
Leave the defaults on the next screen and click next.
Choose Dynamically expanding storage and click next.
Choose where to store the virtual image (make sure you’re storing on a drive with enough space.)
Select he maximum size of the guest operating system disk (I recommend a maximum of 20 GB unless you are sure you need more.)
Now, in the left-hand menu, click the operating system you just created and click Start.
As this is a new installation, Windows will now set up just like it sets up in a non-virtualised (normal) environment. Click Next.
Locate the ISO image or insert the installation disk.
If you opt for an ISO image, you’ll need to add it to the Virtual Media Manager.
Locate the ISO file.
Now select your loaded ISO file.
Now you’re ready to install the operating system you chose, click Next.
Your operating system will now install.
VirtualBox is a great program and you can’t beat free. I dislike how many times I had to click next, Finish, Yes etc. when setting up a virtual machine for the first-time and the interface isn’t the worlds prettiest; however, these are my main complaints with this program and aside from my perceived shortfalls, this is an excellent piece of software.
