This is a cool intro to how virtualization instructions work, but people need to understand that it is not revolutionary simplicity or anything like that. It's just a a cool tech demo lacking all the important bits of a modern hypervisor required to make it practical, like paravirtualized drivers for example.

Same when someone claims to have written an OS in 1000 lines and all it does is get you to real mode with VGA graphics and an interactive (but useless) prompt.

(Note that you can benefit from virtualization technology in specialized scenarios outside common hypervisors, but that's not really what's being demoed here.)

Any thoughts on OsakaOS

		That it's fine to do things just to have fun an mess around, but thats all there is to it. It's not even an OS at the current state. Other small OS's are actually OS's and can be impressive efforts. Sometimes they bring new concepts or paradigms, but that itself is rarely more than a curiosity without impact. Still fun though, at the very least for the authors.
