pyvmomi 實現VMware自動化

運維離不開自動化，python的發展更是給自動化注入了一劑興奮劑；還記得當時公司年會，大家都在嗨皮，苦逼的運維攻城獅還在賣力的給一個大客戶手動開通500台雲主機的情形，現在想想好傻O(∩_∩)O哈哈~。如果早點接觸pyVmomi，就不至於這麼苦逼了。

pyVmomi is the Python SDK for the VMware vSphere API that allows you to manage ESX, ESXi, and vCenter.官方如是說。自己這裡寫篇部落格整理一下，也希望對還停留在手工時代的同學有所幫助。

壞境設定：
1、網路環境：
    安裝pyvmomi的server和VMware vCenter 網路打通；
2、系統環境：
    pyvmomi用pip安裝，所以需要有python和pip;pyvmomi 6.0.0需要的python版本支援為2.7, 3.3 和 3.4, 支援的vSphere 版本為：6.0, 5.5, 5.1 和 5.0。
安裝如下：
$sudo apt-get install python-pip
$sudo pip install pyvmomi
$sudo pip freeze | grep pyvmomi    #檢視安裝的pyvmomi版本，現在是6.0版本
pyvmomi==6.0.0        #如果已經安裝過，升級用pip install --upgrade pyvmomi

或者也可以下載原始碼包安裝,https://github.com/vmware/pyvmomi.git：
$sudo python setup.py install

3、pyvmomi提供了一些社群樣本專案，可以參考編寫自己的程式碼：
git clone https://github.com/vmware/pyvmomi-community-samples.git

4、下面是 pyvmomi給出的獲取所有vm的指令碼：
