基于虚拟机的操作系统教学工具的架构设计

文章提出了一种基于虚拟机技术的操作系统模拟教学工具的开发架构,该系统架构采用虚拟机模拟底层硬件环境的方法,并以此为基础构建模拟的操作系统实验环境,它可以在不改变实验平台的前提下,很好地完成大部分的典型操作系统教学实验,同时减少了一定的相关技术复杂性。架构在设计过程中还考虑了一定的移植性和扩展性,方便以后进行平台移植和功能扩充。此外,该架构不仅可以应用在操作系统领域,对于其他学科的教学系统的构建,也具有一定的参考价值。

The design of the framework based on virtual machine for operating system''''s instructional tool

The paper proposes a new architecture that is based on virtual machine to construct a kind of simulative operating system instructional environment.The framework uses virtual machine to simulate the low-bottom hardware on the basis of which simulative environment of OS is built.In this way many typical OS virtual experiments can be carried out and correlative technical complexity is reduced, but the experimental platform is not changed. During the design of the architecture the portability and extension are taken into account to some extent, So it is convenient to transport and extend the architecture afterwards. In addition, the architecture can be applied not only in the subject of operating system, but also can be referenced in instructional tools of other subject.
