I know VMWare workstation is not the same, but there were VBS-like systems back in the 1970's.
IBM pioneered hardware virtualization for isolation on their System/370 mainframes with VM/370 in 1972.
VMWare ESX hypervisor brought virtualization to x86 servers (2001).
Xen hypervisor introduced open-source virtualization for x86 (2003).
By the time VBS showed up, the concepts were already several decades old.
VBS isn't even the same idea as a full blown VM in a type 1 or 2 hypervisor. I'm not sure why you're attempting to make the comparison.
I am talking about core concepts, not specific implementation details.
VBS uses a hypervisor and hardware virtualization to isolate processes for security. These concepts trace back to systems like the IBM VM/370.
Conceptually it's essentially the same thing. The difference with VBS is the scope and purpose of what's being virtualized.
