    Besides the software mentioned in the article, I would recommend everyone check into the open source VirtualBox application.

    This statement is inaccurate and the term Virtualization was never used in any IBM literature before 2002. The term "Vritualization" was first used by Flash Vos in their literature and patent applications for system virtualization in late 90's.
