Computer system and method for testing hardware device based on virtual machine

A computer system for testing hardware device based on virtual machine, comprising:

• a virtual machine, comprising:
• a guest operating system, comprising:
• a guest driver, installed in said guest operating system, and used for issuing a sequence of test instructions;
• and
• a hypervisor, comprising an expansion test module and a virtual hardware, wherein said test instructions are transmitted by said guest driver to said virtual hardware in turn via said expansion test module, and said virtual hardware is allowed to process said test instructions so as to generate at least one response signal and said response signal is then transmitted to said guest driver via said expansion test module.

A computer system for testing hardware device based on virtual machine, comprising:

• a virtual machine, comprising
• a guest operating system, comprising:
• a guest driver, installed in said guest operating system, and used for issuing a sequence of test instructions;
• and
• a hypervisor, comprising an expansion test module and a virtual hardware, wherein said test instructions are transmitted by said guest driver to said expansion test module in turn, and said expansion test module is allowed to generate at least one response signal directly if it is capable of processing said test instructions;
• otherwise, said test instructions are transmitted, by said expansion test module, to said virtual hardware, by which said test instructions are processed and said response signal is then generated, and then said response signal being transmitted to said guest driver via said expansion test module.

A method for testing hardware device based on virtual machine, said method being applied to a computer system installed with a virtual machine, said virtual machine comprising a guest operating system and a hypervisor, in which said guest operating system is installed with at least one guest driver, and said hypervisor comprises an expansion test module, said method comprising the steps of:

• issuing a sequence of test instructions and then transmitting said test instructions to said expansion test module by said guest driver;
• transmitting said test instructions to a real hardware or a virtual hardware by said expansion test module;
• processing said test instructions so as to generate at least one response signal by said real hardware or said virtual hardware;
• and
• transmitting said response signal to said guest driver via said expansion test module by said real hardware or said virtual hardware.
