虚拟机技术在计算机实验中的应用

Application of Virtual Machine Technology to Computer Experiments

采用虚拟机技术可以让一台物理计算机模拟多个虚拟计算机,从而解决计算机学科较强的实践要求问题。常用的虚拟机软件属于硬件抽象层虚拟机产品,包括VMWare系列产品、Microsoft VirtualPC/Server和Sun xVM Virtual Box等。虚拟机系统的需求,可以根据自己所建虚拟机的多少,通过列表来计算系统实际所需的磁盘空间和内存容量。虚拟机在实验中可以进行应用软件实验,网络实验,系统安全实验。利用虚拟机技术创建计算机实验环境,是一种有益的尝试,它不仅可以缓解实验设备不足的问题,提高已有系统的利用率,并且可以减少实验室的管理难度。在较少的投入条件下,其实验效果与物理机效果完全一致,各项操作更为真实可见,非常适合高校的实验教学需要。

Use of virtual machine technology can make a physical computer simulate several virtual computers and solve the practical problem in computer science. Generally- used virtual software belongs to hardware abstract layer, including VMWare series products, Microsoft VirtualPC/Server and Sun XVM Virtual Box. The system requirements of the virtual machine may list disk space needed by the system and memory capacity according to the number of them. In the computer experiment, the virtual machine technology not only release lack of experimental equipment but improve its system utilization. Besides, it can decrease the difficulty in management. With less investment, its experimental result is the same to that of physical machines. Its operation is seen and fit for experimental teaching in colleges and universities.
