config.sxp，内容包括宿主系统的类型，网络的连接结构、宿主操作系统的资源使用设定，以及vnc连接的一些内容。（如果你想增加一个虚拟网络设备的话，是需要在这里设定的）五、/etc/xen/auto 的含义是如果你想让被虚拟系统随着宿主系统一同启动的话，就把虚拟系统的配置文件放到这个目录下面来。六、/etc/xen/scripts 是些脚本文件，用于初始化各种虚拟设备，比如虚拟网桥等。（如果要增加一个虚拟网络设备，同样需要在此处调节）七、在/etc/xen下面会有些配置文件，这就是虚<img src ="aggbug/2449617.aspx" width = "1" height = "1" />Fri, 16 May 2008 05:05:00
