运维离不开自动化，python的发展更是给自动化注入了一剂兴奋剂；还记得当时公司年会，大家都在嗨皮，苦逼的运维攻城狮还在卖力的给一个大客户手动开通500台云主机的情形，现在想想好傻O(∩_∩)O哈哈~。如果早点接触pyVmomi，就不至于这么苦逼了。

pyVmomi is the Python SDK for the VMware vSphere API that allows you to manage ESX, ESXi, and vCenter.官方如是说。自己这里写篇博客整理一下，也希望对还停留在手工时代的同学有所帮助。

坏境配置：

1、网络环境：

安装pyvmomi的server和VMware vCenter 网络打通；

2、系统环境：

pyvmomi用pip安装，所以需要有python和pip;pyvmomi 6.0.0需要的python版本支持为2.7, 3.3 和 3.4, 支持的vSphere 版本为：6.0, 5.5, 5.1 和 5.0。

安装如下：

$sudo apt-get install python-pip
$sudo pip install pyvmomi
$sudo pip freeze | grep pyvmomi     #查看安装的pyvmomi版本，现在是6.0版本
pyvmomi==6.0.0        #如果已经安装过，升级用pip install --upgrade pyvmomi

或者也可以下载源码包安装,https://github.com/vmware/pyvmomi.git：

$sudo python setup.py install

3、pyvmomi提供了一些社区样本项目，可以参考编写自己的代码：

git clone https://github.com/vmware/pyvmomi-community-samples.git

4、下面是 pyvmomi给出的获取所有vm的脚本：

5、执行之后输出格式如下：
