Where to Download Free VirtualBox Images (.vdi) and How to Use Them: VirtualBox, arguably the most popular free and open-source virtualization software for Linux is a great tool for trying other operating systems without the need for additional hardware. I utilize VirtualBox for installing and running Windows 7 as guest OS on Ubuntu, and also use it for testing other Linux distributions.
To run an operating system inside VirtualBox, you will need a CD/DVD or image installer of the guest OS so you may have to download it, and then set it up and wait until the installation is finished. If you are always in the mood to try other Linux distros or operating systems, you may find this a time-consuming process.
So what should you do to save some of your precious time? You may download a VirtualBox disk image (.vdi) file of your preferred operating system. Now, where can you download free VirtualBox images? You can go to torrent sites like isohunt.com and search for .vdi. You can also go to virtualboximages.com and virtualboxes.org where you will find direct links to tons of VirtualBox images of different Linux distributions and also BSDs. You may also use Google if you are not lazy enough.
How to use VDI file?
Run VirtualBox and start by adding a new virtual machine the way you normally do. But once you reach the “Virtual Hard Disk” part, select “Existing” to open up the VirtualBox Virtual Disk Manager. Using the VirtualBox Virtual Disk Manager, simply attach or add your downloaded .vdi file, and then finish it up. You can now start the virtual machine with your guest OS already installed, so no more waiting.
That’s about it. I hope you will find this useful.
PS. When looking for.vdi torrents, always get it from trusted torrent sites like isohunt, mininova, et. To be safe, read comments associated with the torrent file to find out if it's the real deal. Lastly, use common sense to avoid malware.
