VirtualBox – Open Source Virtualization Software

Are you tired of setting up another machine/s just to show the features of another operating system? Or do you find it hassle to (re)boot your computer and wait for minutes just to load another OS? There’s a simple solution for these – VirtualBox!

Quoting directly from its website:

VirtualBox is a powerful x86 and AMD64/Intel64 virtualization product for enterprise as well as home use. Not only is VirtualBox an extremely feature rich, high performance product for enterprise customers, it is also the only professional solution that is freely available as Open Source Software under the terms of the GNU General Public License (GPL) version 2.

Try it, it’s free and open source! It simply works (more than 90% of the time). I’ve been using this virtualization software since I was an undergraduate student in developing and testing different applications for different platforms. Now, I’m using it to teach my students the features of operating systems especially Linux OS’s. Although it is compatible with any operating system, VirtualBox is hosted on my Mac, the best of both worlds. 🙂

Recently, I’ve encountered a “Failed to open a session for the virtual machine” error whenever I load any VM that is currently installed on my VirtualBox. Fear not, this can be easily fixed by just a Repair Disk Permissions process (if you’re using a Mac) or a change in root ownership and permissions (if you’re using Linux).

How about you? Do you have better suggestions on virtualizing operating systems? Feel free to leave a comment. 🙂
