Virtualization will enable users to concurrently run multiple operating systems and applications in independent partitions of a system. Mainframes have had this kind of technology for some time, now AMD plans to bring it more into the mainstream. Software and hardware technologies work together in AMD's Pacifica to help reduce complexity and increase security of new virtualization solutions.
AMD plans to make Pacifica available in the first half of 2006. Intel, of course, has its own virtualization strategy called "Vanderpool", which will be available in Itanium processors later this year.
