通過vmware tools來為克隆出來的虛擬機器配置IP地址薦

Windows和Linux配置IP地址都很簡單，但前提是你能直接訪問它們。

如果是一個剛完成克隆的虛擬機器，如何配置IP地址呢？我們不能總是人工去做，但沒配IP之前，系統自身的一切介面都不能用，只能從vmware tools上想辦法了。上一篇裡提到vmware tools可以在沒網路的情況下傳輸檔案，其實它還可以在沒網路的情況下登入到作業系統中執行指定命令。

以下是通過pysphere來調vmware tools，進入虛擬機器中執行命令的程式碼，目前可以在ubuntu/RedHat/Windows2003上使用。其實只要定製相關的指令碼或命令，vmwaretools只是起一個通道的功能。
