Virtual Machine/Conversational Monitor System

<operating system>

(VM/CMS) An IBM time-sharing and personal computing environment executing under Virtual Machine (VM) in a virtual machine environment. VM/CMS is designed to support large numbers of interactive users. It relies on numerous APIs into the Control Program (CP) to provide very efficient single-user processing

VM/CMS was only adopted some time after the original design of Virtual Machine as a more efficient personal computing environment than MVS/TSO.
