An ISO is a file that is an exact "image" of a CD or USB stick.

No matter what OS you want to virtualize, you will need an ISO of the install disk(s) for that OS. When you select the name of an operating system in the "Create a VM" wizard, all it is doing is changing the VM settings to be optimized for the OS you chose. What operating system is it that you want to create a VM with? A lot of people who download VirtualBox for the first time think that the operating systems are included - but they are not. Often, the same task can be accomplished with simpler means, but that's for a totally different article. One last thing before we get started - make sure you actually need a VM for whatever it is you are trying to achieve.

The "guests" are just there temporarily, using some of the hosts' resources, but they don't really have full control. We use these terms because it's like a house - the host OS "owns" the machine for the most part. The "guest" is the OS running inside the virtual machine. On most PCs, it's Windows, and on Apple machines, it's Mac OSX. The "host" OS is the one that starts when you turn your computer on. I've been using the words "guest" and "host" a lot - I guess I should define those also. You can still run older stuff, but your machine simply does not have enough RAM to share with a VM and still run smoothly. If your laptop/PC has less than 8GB of RAM, you will have trouble running virtual machines of modern operating systems. Why is this important to understand? When creating a VM, you have to make sure that you leave enough resources for the host OS to run smoothly. It can't directly interact with the host OS. However, the VM runs in a sort of "bubble". This means that when you run a virtual machine, it is essentially "sharing" the computer with whatever OS you are running. Modern computers actually have a special mode built into the processor to handle virtual machines, called Virtualization Technology. A virtual machine is, as the name implies, literally a virtual computer. How To Make a Virtual Machine (From Scratch) Before Startingįirst of all, if you've never used or created a virtual machine (VM) before, then you need to understand a few important concepts that will make everything a lot easier for you down the line.
