We should mention the various virtualization hardware assists built-into
Intel and AMD CPUs
which allow VMs to run with near-native performance. Not to mention the
assistive code in
the linux kernel itself eg. TLB, etc. These technologies were available
beginning in the early
1960s (Atlas) and especially after 1965 (OS/360) and again after 1970 (MVS
and VM/370) in
the IBM mainframe universe.
