Miscellaneous

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.

Virtualization may reach mobile devices soon.
