随着科技的发展,信息技术日益受到人们的重视,新课标中也强调了信息技术教学中增强学生动手操作能力的重要性。然而在高中的教学体系中,信息技术一直作为边缘科目得不到重视,进而导致学校机房硬件设施无法满足教学需求现象的发生。对此,引进虚拟机技术就显得尤为重要了。虚拟机是在一台普通计算机上虚拟出来的独立逻辑计算机。它构造出了一个完整的计算机系统,拥有独立的CPU、内存、硬盘、适配器等。通常情况下,一台计算机上可以同时运行多个虚拟计 With the development of science and technology, information technology is paid more and more attention by people. The new curriculum standard also emphasizes the importance of enhancing students’ ability of hands-on operation in information technology teaching. However, in the teaching system of high school, information technology has not been taken as an edge subject, which leads to the fact that the hardware facilities of the school computer lab can not meet the demand of teaching. In this regard, the introduction of virtual machine technology is particularly important. A virtual machine is a separate logical computer that is virtualized on a common computer. It constructed a complete computer system, with independent CPU, memory, hard drive, adapter and so on. Often, multiple virtual meters can run simultaneously on a single computer
