客户操作系统中断虚拟化的研究与实现

Research and Implementation of Interruption Virtualization in Guest Operating System

为解决操作系统在运行于虚拟机管理器提供的虚拟化环境中,无法直接处理系统中的中断的问题,针对虚拟化操作系统的中断处理,结合虚拟机管理器所能提供的功能,提出了一种中断虚拟化的模型,并以Vx Works 5.5为验证对象进行了中断虚拟化的实现以及验证,通过验证结果表明,中断虚拟化模型能够保证客户操作系统中断的正常处理。

Operating systems can not directly handle all the interrupts in system after running on the virtual environment provided by the hypervisor. this paper focus on interrupt handling in virtualized OS,combined with the functions provided by Hypervisor. we propose a scheme of interrupt virtualization. finally use Vx Works 5. 5 as the object for the verification of the interrupt virtualiztion,and the result shows that the interrupt virtualization solution can guarantee the guest OS handle the interrupt normally.
