I think that it was introduced in 2000.
While providing an abstracted view of the hardware, an operating system also brings some baggage. One bag contains security holes that the applications that run upon the operating system do not have.
The same is true for hypervisors. The more features that are integrated into the hypervisor such as management facilities, the more vulnerabilites arise. An operating system places a bunch of applications at increased risk and a hypervisor places a bunch of guests and even more applications at risk.
"Each Libra 780/790 mainframe cell board sports from 4 GB to 128 GB of DDR2 main memory, which is formatted down to 3 GB to 96 GB of addressable memory for MCP workloads. (Presumably there is some memory sparing magic going on)"
This is likely due to the fact that the original MCP uses a 48bit word with in memory tags to inicate the type of operand that was stored at that location.
