What is the difference between a virtual machine and a virtual machine operating system? I thought all VMs were operating systems. I came across the phrase here:
VM (often: VM/CMS) refers to a family of IBM virtual machine operating systems used on IBM mainframes System/370, System/390, zSeries, System z and compatible systems, including the Hercules emulator for personal computers

A Virtual Machine is typically software that emulates a computer.
A VM OS is an operating system that runs inside the VM.
But don't quote me on that.

See VM/CMS.
