Is Virtualisation the Same as Cloud Computing?

Extract . . . 

A recent Reuters news item that equates virtualisation and cloud computing is symptomatic of the ongoing confusion between the two terms. Without splitting hairs, are these really the same? 

Here's the statement from the article "Dell To Buy Storage Company 3PAR for $1.15 billion"): "International Business Machines Corp has been expanding its services business, as have other rivals like Hewlett-Packard Co and Oracle Corp. Such companies have also been stepping up investment in cloud computing, or 'virtualisation', a technology that enables users to access data and software over the Internet and corporate networks." 

(The underlining is mine. Also, let us ignore that last bit about technology enabling access to data and software over the internet -- which could be one of several 'technologies', for example IP.)
