Tecniche di virtualizzazione nelle architetture Intel/AMD   PDF
Operating System Course Lecture, June 2007, Politecnico di Bari, Italy

StoMach   PDF
Hurdmeeting 2005, Madrid, Spain

StoMach was my attempt at solving the GNUMach drivers problem using the OSKit project. Another attempt was taking place at the time, called oskit-mach, but this approach was substantially different as it aimed at keeping the internals of Mach unchanged and using OSKit's COM-based drivers through a proper mach interface. Did work, well enough. And there was definitely an improvement by being able to boot HURD using Linux 2.2 drivers instead of Linux 2.0 drivers in 2005!
