CP-67 is a hypervisor, or Virtual Machine Monitor, from IBM for its System/360 Model 67 computer. CP-67 is the control program portion of CP/CMS, a virtual machine operating system developed by IBM's Cambridge Scientific Center in Cambridge, Massachusetts.

CP-67/CMS was the first widely available virtual machine architecture. IBM pioneered this idea with its research systems M44/44X (which used partial virtualization) and CP-40 (which used full virtualization).

Simplex—one IBM 2067-1 processor, two to four IBM 2365-2 Processor Storage components (512K to 1M bytes), up to seven data channels, and other peripherals. This system was called the IBM System/360 model 67–1.

IBM's 360/67 was a 360/65 with virtual memory operations added to the CPU. The machine supported paging and segmentation, 4096 segments each with 256 4Kbyte pages, and had other modifications that made it possible to simulate multiple virtual 360s efficiently.

I am designing an operating system, and I want to add this command to my operating system.

Perhaps IBM pioneered the virtual machine when they built CP67 in about 1967 which ran on the 360 model 67 which was IBM’s first machine with virtual memory. CP67 was a privileged mode program that provided multiple virtual machines, each very much like a real machine.
