z/VM is the current version in IBM'sVM family ofvirtual machineoperating systems. First released in October 2000,[2] z/VM remains in active use and development as of 2024[update].[3] It is directly based on technology and concepts dating back to the 1960s, particularly IBM'sCP/CMS on theIBM System/360-67 (see articleHistory of CP/CMS for historical details). z/VM runs on IBM'sIBM Z family of computers and can support large numbers (thousands) of Linux virtual machines. (SeeLinux on IBM Z.)
On 16 September 2022, IBM released z/VM Version 7.3 which requiresz/Architecture, implemented in IBM'sEC12,BC12 and later models.[4]
