Hardly. IBM was working with virtual machines as far back as the IBM S360/67 in the late 60s (and even a highly modified /40), and released VM/370 in 1972. They used the term 'Virtual Machine' as early as 1966: R. J. Adair, R. U. Bayles, L. W. Comeau, and R. J. Creasy, A Virtual Machine System for the 360/40, IBM Corporation, Cambridge Scientific Center Report No. 320-2007 (May 1966) https://en.wikipedia.org/wiki/VM_%28operating_system%29 (And that's just what I'm familiar with from being a VM jock from 1982 to 2000, I'm sure there's earlier references...)
