- Perhaps Intel should work with IBM's mainframe division. The s/370
- machines could virtualize themselves. I've seen the VM operating
- system running in a VM-hosted virtual machine. I've also seen the MVS
- operating system running in a VM-hosted virtual machine. This is
- particularly useful for debugging new versions of the operating system
- - you just run it in a virtual machine under the older (and stable)
- version until it stabilizes.
-
- If IBM can make a 370 that can produce virtual 370's, Intel should be
- able to make a 486 that can produce virtual 486's. They just haven't
- done it yet.
