Paralleling multi-processor virtual machine system

Abstract

The invention discloses a concurrent multiprocessor virtual machine system supporting CPU simultaneous execution, which comprises a virtual machine and an operating system running on the virtual machine. The virtual machine system can simulate not less than one virtual processor, which comprises a processor concurrent simulation module, a memory management module, an interrupt controlling simulation module and a peripheral simulation module; the machine instruction of the operating system is transferred to the processor simulation module through the memory management module of the virtual machine; the processor simulation module can simulate multiple virtual processors used for executing the operating system instruction translated by an instruction translation module and make the processors concurrently execute; the invention also provides a synchronous and access control algorithm in the concurrent execution process; and the peripheral simulation module and the processor simulation module are coordinated by the interrupt controlling simulation module. The invention has the advantages of suitability for simulating a concurrent execution environment of complete simulating hardware on an SMP server or a multi-core server.

Description

technical field [0001] The invention relates to a computer system structure, in particular to a parallel multi-processor virtual machine system, which enables multiple virtual processors to run in parallel on a modern multi-processor server platform. Background technique [0002] The operating system plays a very special role in today's personal computers and servers. It is like a bridge that bridges the gap between user applications and hardware platforms. For a long time in the past, only one operating system could run on a computer at any given time. Therefore, in order to enable multiple operating systems, or application programs of different operating systems to run simultaneously on the same computer, scientists have invented many methods and technologies. [0003] Virtual machines are widely used as a powerful and convenient technology. [0004] System-level virtual machines simulate all components of a computer system with high precision. In this way, the operatin...

Problems solved by technology

Traditional virtual machines (such as: Bochs IA-32 Emulator: http: / / bochs.sourceforge.net / ) When constructing a user execution environment with multi-processing resources, in order to realize the synchronization of execution units, the execution content of multiple processing units is actually placed in a loop for serial execution, and its efficiency is very low
