5 VM host architecture Guest OS Exceptions Ring 0 Ring 3 Hardware emulation x86 emulation VM monitor Host address spaceGuest address space Micro OS API calls Real hardware PREC VGA card Direct access

6 Virtualization technique - Adding special mode for AMD processor. In this mode all privileged instructions should cause an exception when running on 3-rd protection ring. Guest code running natively in VM monitors address space on 3-rd protection ring. All privileged instructions cause an exception and emulated by VM monitor. - Guest code running natively in VM monitors address space on 3-rd protection ring. All privileged instructions cause an exception and emulated by VM monitor. - No code scanning or translating needed. Guest code perfomance depends on IO intensity and only times slower than on real PC - Some IO devices (PREC VGA card for example) are managed directly by guest code without emulation
