Tutorial: Getting started with pyVmomi on Windows : Supports vSphere 6.7

HOME, Vmware private AI and IaaS platform, vSphere API, , ,

Couple of months back, I wrote an article on “How did I get started with pyVmomi on ubuntu distro?”, which was very well received.  Recently I got several requests from readers  on how to set pyVmomi on Windows platform and I thought to write this tutorial, which will take you through steps required to set pyVmomi on my Windows 10.

Step 1: Install latest python for windows.

Latest 3.x python version available is 3.6.5 on python official portal . Download the python installer as pointed out in below screenshot.

Once downloaded, while installing python, make sure to select checkbox “Add python 3.6 to PATH” as shown below.

As soon as installation is completed, I checked environment variable and I see that python 3.6 path is set properly as shown below.

I see that python is installed as expected at directory i.e. C:\Users\shitolev\AppData\Local\Programs\Python\Python36, which is default directory. I also checked python version using “python -V” command and I see correct python version is installed.

Step 2: Install pyvmomi and pyvim python modules

As I already discussed in my pyVmomi on ubuntu article, we need “pip” to install these python modules. Note that “pip” itself gets installed as part of python installation. Let us go ahead for “pyvmomi” and pyvim” modules installation by running this command
“python.exe -m pip install pyvmomi pyvim” . You can run this command from any directory of your choice.

Below is how it looks like

you can see that latest “pyvmomi” i.e. the one supports vSphere 6.7  and “pyvim” python modules got installed successfully. I also see that these modules are installed at python  directory i.e. C:\Users\shitolev\AppData\Local\Programs\Python\Python36\Lib\site-packages

Now that we are done with setting up pyVmomi on Windows, its time to run a vSphere API sample to confirm everything is working fine.

Step 3: Running vSphere API sample.

For the sake of simplicity I chose the same sample I used in my ubuntu article

[python]
# VMware vSphere Python SDK, pyvmomi
# Simple script to get vCenter server product details

from pyVim.connect import SmartConnect
import ssl

s=ssl.SSLContext(ssl.PROTOCOL_SSLv23) # For VC 6.5/6.0 s=ssl.SSLContext(ssl.PROTOCOL_TLSv1)
s.verify_mode=ssl.CERT_NONE

si= SmartConnect(host="10.192.1.2", user="Administrator@vsphere.local", pwd="VMware#123", sslContext=s)
aboutInfo=si.content.about

print ("Product Name:",aboutInfo.fullName)
print("Product Build:",aboutInfo.build)
print("Product Unique Id:",aboutInfo.instanceUuid)
print("Product Version:",aboutInfo.version)
print("Product Base OS:",aboutInfo.osType)
print("Product vendor:",aboutInfo.vendor)

[/python]

We can keep this sample file at any location of our choice and execute it as follows.

Output shows that this small pyvmomi script got executed on vSphere 6.7 successfully. How cool is that?

Note: I would like you to take a look at line #7, where I had to use “ssl.PROTOCOL_SSLv23” protocol for VC 6.7 connection. For VC 6.0 and 6.5, I used “ssl.PROTOCOL_TLSv1”.
