Nice writeup! > The VMM emulates some interesting hardware: a device that can read the latest tweet from Command Line Magic’s Twitter handle, a device that can get the weather from certain cities, another device that can read fetch the latest air quality measurements from certain cities and finally a console device that lets the virtual machine read the keyboard and output text to the terminal. This is one of the under-appreciated fun things about virtualization: the ability to pretty much make up 'hardware' devices, and completely rethink the way that the hardware should work. No need to be a PC when you can be anything you want. Obviously it's possible to do all the same stuff with hardware, or even kernel drivers, but the KVM interface makes it really easy and fun.
