For example, with a Windows 10 installation, it’s possible to need more than 10G of disk space. VirtualBox itself is rather small needing only around 30M of space, but the files for the distribution will vary. As for the disk space, this will also vary based upon the distribution that you are using. This also assumes you have a relatively new processor for your server or computer. For any Windows distribution, you will want at least 2G of RAM just for the virtual machine. You will also want to check the minimum RAM requirements of the guest operating system.

You will need at least 512 MB of RAM to run a different Operating System, but likely you will want a lot more say, 2 to 3 G of RAM and in general, the more RAM you have, the better the performance of the virtual machine. If you have any questions regarding these steps we advise reviewing Oracle’s excellent documentation. For this tutorial, we will give you the steps to installing the Oracle option as it is the industry standard. There are two open-source options for VirtualBox, one from Ubuntu and the other from Oracle. The only limitations are RAM and disk space for running each virtual machine.

This is handy when you need to run software that is only available on one Operating System, for example, if you wanted to run Windows software on your Ubuntu computer or vice versa.
