通过vmware tools来为克隆出来的虚拟机配置IP地址

Windows和Linux配置IP地址都很简单，但前提是你能直接访问它们。

如果是一个刚完成克隆的虚拟机，如何配置IP地址呢？我们不能总是人工去做，但没配IP之前，系统自身的一切接口都不能用，只能从vmware tools上想办法了。上一篇里提到vmware tools可以在没网络的情况下传输文件，其实它还可以在没网络的情况下登录到操作系统中执行指定命令。

以下是通过pysphere来调vmware tools，进入虚拟机中执行命令的代码，目前可以在ubuntu/RedHat/Windows2003上使用。其实只要定制相关的脚本或命令，vmwaretools只是起一个通道的功能。
