OSNews, Generic OSes Now that you have an idea of where your OS project is heading as a whole, it's time to go into specifics. The first component of your OS which you'll have to design, if you're building it from the ground up, is its kernel, so this article aims at being a quick guide to kernel design, describing the major areas which you'll have to think about and guiding you to places where you can find more information on the subject.

Hybrid windows

Windows is more hybrid in recent years since the introduction of User-mode Driver Framework: http://en.wikipedia.org/wiki/User-Mode_Driver_Framework
IIRC, Aero graphics drivers run in usermode.

Another VM-based OS that's had some coverage on OSNews is Phantom OS: http://dz.ru/en/solutions/phantom/
Their goal is full persistence of all processes, data etc across shutdowns. Last blog post was October 2010 so perhaps it's not dead yet.
