本文将带你了解Vmware之网络环境，希望本文对大家学Vmware有所帮助。

<

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：
$sudoapt-getinstallpython-pip
$sudopipinstallpyvmomi
$sudopipfreeze|greppyvmomi#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pipinstall--upgradepyvmomi
或者也可以下载源码包安装,https://github.com/vmware/pyvmomi.git：
$sudopythonsetup.pyinstall
3、pyvmomi提供了一些社区样本项目，可以参考编写自己的代码：
gitclonehttps://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：
