To understand
this, one has to consider some of the earlier VM
systems. 2 more efficient methods, for example, are the IBM mainframe
style, with a relatively simple hypervisor OS to host the virtual
machines - such as IBM VM, currently z/VM - running more full-
function
guest OSs that present the actual functionality needed by user
applications.
Well, there is one feature that VM has that I've not seen in many
other situations. VM can run as a guest under VM.
