Virtual machine for a high level programming language vs an operating system

It struck me recently that a virtual machine for a high level programming language is very much like an OS. It manages resources, e.g. stack, heap, etc. similar to how an operating system manages resources and if the programming language supports threads then the virtual machine also does time-sharing and context switching similar to how an operating system does it.
