虚拟机中网络连接问题的研究

在网络安全研究方面和网络运营商提供的服务中,虚拟机技术越来越起着重要位置.虚拟机的网络连接问题是首要解决的问题.在平时工作和研究中,人们对虚拟机网络连接概念模糊,相关的参数设置考虑不全,造成虚拟机找不到宿主机或宿主机找不到虚拟机,以至于虚拟机无法访问互联网.本文以虚拟机的三种网络连接模式为线索,论述不同连接模式下虚拟机与物理机在网络中的关系,以及虚拟机与宿主机的IP地址、子网掩码、网关和DNS服务器地址,阐明虚拟机网络连接参数设置方法.

Research on network connectivity problem in virtual machine

In the study provide network security and network operators service,virtual machine technology plays an increasingly important position.Virtual machine network connection problems is the primary problem to solve.In the normal work and study,people in the virtual machine network connecting the concept of fuzzy,parameter settings related to consider incomplete,resulting in the virtual machine can＇t find the host or host not found that virtual machine,virtual machine can not access the internet.Based on the three kinds of network virtual machine connection mode as the clue,discusses the different connecting the virtual machine and the physical machine mode in a network of relationships,as well as the virtual machine and the host IP address,subnet mask,gateway and DNS server address,clarify the virtual machine network connection parameter setting method.
