Xen is a hypervisor distributed through the Open Source method. It's available at no cost, and the firm claims it offers "near native" performance for virtualised applications.
Founders of Xen include Cambridge University's Ian Pratt, Nick Gault, and Moshe Bar.
Pratt and his co-founders at Cambridge Uni will continue to develop the technology, but representatives of Kleiner Perkins Caulfield Byers and Sevin Rosen Funds, the venture capitalists, will join XenSource's board of directors. µ
