The virtual machine design was initiated by BBN and their paging box that brought the Tenex operating system into existence in the early 70s. That was on KA machines. Then DEC brought out the KI machine with similar but not identical features in the mid 70s. Then DEC brought out the KL machines In the late 70s. Tenex was ported to those machines by non DEC people.  Somewhere DEC got wise and bought the rights to something and came out with Tops20, a very decent clone of Tenex with a superior file system.
