z/VM is the current version in IBM's VM family of virtual machine operating systems. z/VM was first released in October 2000[1] and remains in active use and development as of 2016[update]. It is directly based on technology and concepts dating back to the 1960s, with IBM's CP/CMS on the IBM System/360-67 (see article History of CP/CMS for historical details). z/VM 6.4 runs on IBM's System z family of computers. It can be used to support large numbers (thousands) of Linux virtual machines. (See Linux on z Systems.)
On October 16, 2016, IBM released z/VM Version 7.1 which requires z/Architecture, implemented in IBM's z196, z114 and later models.[2]
