The changing virtual machine environment: Interfaces to real hardware, virtual hardware, and other virtual machines
Ron MacKinnon · IBM Systems Journal · 1979
One can envision future uses of virtual machines that will exploit a proliferation of multiple, interconnected real and virtual machines. While the interconnections may be local or commhnications-based, the logical view can remain the same. VM/370 attached processor support48can be viewed as a first step—for large systems and in a tightly-coupled context. Multiple logical and real systems (large or small) are appropriate and fertile fields for future experimentation and investigation.
