Will 2008 become the Virtual Year? Thats what some people would have us believe now that the virtualization hype is reaching never before seen heights, and large acquisitions & mergers are starting to become quite common ( Citrix bought Xensource, Novell picked up PlateSpin, Sun acquired innotek, Quest Software snapped up Vizioncore while VMware treated itself to Thinstall, and so on). But few people realize or fail to acknowledge that the large majority of virtualization techniques and developments were started as, or remain Open Source projects. Where are we coming from ?
