Virtualising an operating system is an increasingly common operation that has many advantages. This makes it very easy to emulate a Linux system or XP on Windows Vista with this excellent program that is VirtualBox. An effective way to easily test risky manipulations without taking any risk. Curious about such a principle? Follow the guide!

According to Wikipedia:
“ In computer science, we call virtualisation all hardware and/or software techniques that allow several operating systems and/or applications, separately from each other, to be operated on a single machine as if they were operating on separate physical machines. Virtualisation tools are used to operate what is commonly called Virtual Private Servers (VPS) or Virtual Environments (VE). “

In short, virtualisation software will allow us to use an operating system in the one you are currently using. For example, you can run Vista in Vista, XP in Vista, Ubuntu in Vista, etc. All combinations are possible!
In our example, we will emulate the Ubuntu Linux distribution in a Home Premium version of Windows Vista.
To complete this virtualisation operation, download the following program:
Once downloaded, install the program and launch it.
Virtualisation of a Linux Ubuntu system on Windows Vista
Configuration of a virtual machine
First of all, you must have a live Ubuntu CD on hand which you can download to the following address if you do not own it:
Insert the Live CD into the drive — close the automatic run warning, then return to VirtualBox. Here, click on Nouveau.
Click for the first time on Next. Now indicate the name that you want to assign to this virtual machine — for example, Ubuntu. Then select the operating system then the version correspondent.
Note the considerable extent of supported OSes. To validate, click on Next.
Let’s now set the amount of memory that will be allocated to it. Depending on operating systems, VirtualBox sets a default setting. For Ubuntu, the value is 384 Mo which suits perfectly.
Click again on Next.
The last step is to create a virtual hard drive that will be used to boot — start, the virtual machine in the same way as if you turned on your PC. Wait till you see the rest, you‘ll better understand where I’m going.
Again, VirtualBox sets us a reference value that is set at 8 192 MB. To create the virtual hard drive, click on the button New... then click for the first time on Next and check the box Dynamic-sized disk image — this will allow us to save disk space because the software will not immediately use the 8 GB but will increase the basic size as it needs up to these 8 GB.
Click once more Next. We now need to define the location and size of the virtual hard drive. Leave all default values unless you want to specify a location different from that proposed for disk space reasons. Also note that the 8 GB are well determined.
Click on Next then on Finish twice.
Congratulations, your virtual machine is now operational. We will now explore the various features.
Start-up of the virtual machine
To better understand the use of VirtualBox, I have used video support — your opinions on this use will be welcome.
You now have a minimum of knowledge to engage in more in-depth virtualisation tests. Do not hesitate because I remind you that virtualisation is safe!
