'Virtualization' Is Pumping Up Servers -

"Still, no one is disputing that virtualization is hot. VMware, the EMC Corp. unit that helped invent the category, reported an 80% jump in 2006 revenue -- and recently announced plans to offer 10% of its shares to the public. Microsoft Corp. now sells virtualization software, and a rival called Xen is being offered on the same open-source basis as the popular Linux operating system.
Virtualization is an idea that originated on mainframe systems in the 1960s. But it has been rejuvenated by the rapid spread of x86 servers, which usually run one primary application program and an operating system. As a result, many machines operate at just 10% to 25% of their capacity."
