complete system virtualized several host architectures (supported OS: Linux, MacOS 9/X, Windows) where it is able to different host architecture.
a project that realizes a Just the system are virtualized without booting a guest operating system for different hardware architectures. Dynamic Code Translation techniques can speed-up the architecture (Processor and Peripherals) are virtual. There is to bochs but it implements a PPC architecture instead on standard emulation techniques thus it is virtual (emulated). Is slower than the host operating system.
