　　The datasheet is also interesting because it provides an updated list of the major Xen contributors: Intel, AMD, HP, Dell, IBM, Novell, Red Hat, Sun, Fujitsu, Samsung, and Oracle.
　　While most of the companies listed above are well-known names, finding a telco giant like Samsung is pretty uncommon.
In November 2007Samsung was working to bring Xen on PDAs. In June 2008 virtualization.inforeportedthat the company was porting Xen on the ARM architecture.
