Virtual Machine/System Product ==>
Virtual Machine
<operating system> (VM) An IBM pseudo-operating system hypervisor running
on IBM 370, ESA and IBM 390 architecture computers.
VM comprises CP (Control Program) and CMS (Conversational Monitor System)
providing Hypervisor and personal computing environments respectively. VM became
most used in the early 1980s as a Hypervisor for multiple DOS/VS and DOS/VSE
systems and as IBM's internal operating system of choice. It declined rapidly
following widespread adoption of the IBM PC and hardware partitioning in
microcode on IBM mainframes after the IBM 3090.
VM has been known as VM/SP (System Product, the successor to CP/67), VM/XA, and
currently as VM/ESA (Enterprise Systems Architecture). VM/ESA is still in used
in 1999, featuring a web interface, Java, and DB2. It is still a major IBM
operating system.
