中文摘要: 操作系统原理课程普遍存在实践教学设备的缺乏和低效，为此，提出一种采用插桩技术的可视化操作系统虚拟实验室VOSLS(A Visual Operating System Virtual Lab Using Stub Method)。采用插桩方案调试用于实验的操作系统内核，将复杂的GDB调试协议简化为简单的插桩通信协议；以软盘或硬盘映像文件为媒介，与运行于虚拟机上的被实验操作系统通信，获取其运行信息，并采用可视化图形引擎技术将获得的运行信息以图形的方式呈现给用户。实际应用表明，借助该虚拟实验室，可有效提高实验教
Abstract:In order to address the lack and inefficiency of teaching tools of the operating system principles course, a VOSLS was proposed. It used Stub method to debug the experimental operating system kernel, and reduce the complex GDB debugging protocols to simple Stub communication protocols. It communicated with the experimental operating system running on a Virtual Machine through the floppy or hard disk image files. Then the running operating system，s information was graphically and vividly delivered to the users by using visualization graphics engine technology. Practice has proved that this system can significantly improve the experimental teaching effect of the operating system principles course.
