VIRTUAL SYSTEM AND INSTRUCTION EXECUTING METHOD THEREOF

摘要

PURPOSE: A virtual system and an instruction executing method thereof are provided to analyze the execution of an application program or an operating program in real time. CONSTITUTION: A VMM(Virtual Machine Monitor)(120) virtualizes a hardware(110). A user domain(140) is operated by a virtualized hardware. A root domain(130) is operated by the virtualized hardware. The root domain manages the user domain. The virtual machine monitor analyzes the execution operation of the user domain in real time. The virtual machine monitor stores the analyzed execution information to the root domain.
