多核虚拟机系统中虚拟机间的通信策略研究

Research on Inter-VM Communication Strategy in Multi-core Virtual Machine System

根据虚拟机间通信方式实现的不同,将虚拟机之间的通信分为3种,从虚拟机间3种通信方式的性能、透明性和可移植性方面进行比较,得出基于共享内存的虚拟机间通信是综合性能最优的虚拟间通信方式,且基于硬件寄存器的虚拟件间通信方式有更好的通信性能,并提出一种将两者结合实现的虚拟机间通信策略。

This paper divides virtual machine communication into three types according to the implementation of inter-Virtual Machine（VM） communication in different levels, compares inter-VM communication performance between the three communication methods from performance, transparency and portability, and proposes an efficient communication strategy for the virtual machine. This proves that the virtual machine based on shared memory communication is the best overall performance of virtual communication methods, and proves that hardware register based with best performance, and proposes a combination of the two virtual machines communication methods to achieve a communication strategy.
