Build a virtual machine with VirtualBox in Linux

Virtualization is almost as old as our beloved integrated silicon chips.
At the beginning of the 1960s, there had been two major computing issues.
First, many individual mainframe models were bespoke, so incompatible.
The other stumbling block was that as integrated processors became more powerful, institutions wanted to implement flexible “timesharing” between multiple users.

IBM dismissed this multi-user batch processing was definitely the future! But in 1963, it lost a large MIT contract to General Electric. Realising its huge mistake, IBM developed the general purpose S/360 architecture, which could be implemented on a wide range of compatible systems. In 1965, IBM released the S/360-76, the world’s first mainframe to support virtualisation. And the rest is very much history.
