The first version, released in 1972, was VM/370, or officially Virtual Machine Facility/370. This was a System/370 reimplementation of earlier CP/CMS operating system. Milestone versions included VM/SP. The current version is z/VM, and is still widely used as one of the main full virtualization solutions for the mainframe market.
