基于微内核的虚拟机间通信加速方法

Acceleration Method for Communication Between Microkernel Based Virtual Machines

基于微内核的虚拟化架构相较于传统的宏内核虚拟化架构,具有可信计算基小,易于完全形式化验证的特点.然而,在基于微内核的虚拟化架构中,即使在同一物理机上运行的不同虚拟机,虚拟机间通信仍需要通过调用网卡驱动传输数据,通信效率低.针对以上问题,提出了一种同一物理机上不同虚拟机间的通信加速方法,通过在网络服务中加入通信数据选择模块和转发模块,使得虚拟机间数据的传输可以直接在内存中完成.实验表明,可以有效提高虚拟机间的通信效率.

Compared with traditional monolithic kemel based virtualization architecture, microkemel-based virtualization architecture has smaller trusted computing base and its security is easier to be verified by formal methods completely. However, in microkernel-based virtualization architecture, communication between virtual machines on the same computer still requires the involvement of network card driver, which leads to low efficiency. In this paper, we propose a method to accelerate communication between virtual machines on the same computer by adding data selection module and data transmission module in the network service of microkernel-base virtuaiization architecture. With the method, communication between virtual machines on same computer can be completed in the memory instead of network card driver. Experiment shows that our method can improve the efficiency of communication effectively.
