Revision as of 20:09, 16 March 2024

During one of my engagements as a Professional Services Consultant I needed to upgrade a vSphere 5.1 environment to vSphere 6.

Not really exciting when you have enough hosts available to play with. But one of the things that I stumbled into is that I wanted to have a list of all the VM's that are hosted within the vSphere environment.

One of the ways to do this is to browse trough the web-client and select the Data Center (or vCenter Server) object and look / export / copy-paste the VM's from the related objects VM tab.

As being a CLI guy for a few years I expected that the vCenter Server or the ESX hosts had this functionality build in... well I was wrong. So after using Google over and over again I discovered that I needed to do this either trough Python or trough Power-shell.

In this post I am going to explain you the Python way. This is really going to a "beginners" guide as I needed to start from the beginning as well.

Below you will find the steps that I had to take (as an absolute vSphere + python beginner) to gather a list of VM's with python.

  1. Install OSX on a separate VM (using Fusion)
  2. Verify the default python version that came with Yosemite
  3. Install pip
  4. Use pip to install pyvmomi
  5. Verify version pyvmomi
  6. Create a new user in vCenter to make python calls to vCenter Server
  7. Execute one of the sample Python scripts in the sample directory (getallvms.py)
  8. Alter the getallvms.py script to only show virtual machine names
  9. Execute getallvms.py again
  10. Try another script that provides information about VM's

Install OSX on a separate VM 〈using Fusion〉

When you are playing around with scripts it is better to not do this form your "production" environment but form a "development" environment because you can break things or ending up installing unnecessary add-ons.

As I am using a Mac I decided to install a new copy of OS X trough VMware Fusion. The procedure for this can he found here. I installed Yosemite.

Note

To "fence" your environment it is also possible to use "virtualenvs" in python in stead of installing a whole new VM .

Verify the default python version that came with Yosemite

The OS X installation came with a pre-installed version of Python. To verify this version we need to issue the following command: 

Iwans-Mac:~ iwanhoogendoorn$ python --version 
Python 2.7.10

In my case version 2.7.10 was pre-installed.

Install pip

Now we need to install pip. Pip is a package management system used to install and manage software packages written in Python. We need this to install pyvmomi. 

Iwans-Mac:~ iwanhoogendoorn$ sudo easy_install pip

Use pip to install pyvmomi

We are using pip to install pyvmomi. 

Iwans-Mac:~ iwanhoogendoorn$ sudo pip install pyvmomi

Verify version pyvmomi

Because its pyvmomi and Python are very picky with version compatibility it is good to know what version pyvmomi was installed. 

Iwans-Mac:~ iwanhoogendoorn$ /usr/local/bin/pip show pyvmomi

Get pyvmomi repo from github

The pyvmomi repo consists of sample scripts that can be used to test out stuff. We need to download / clone this repo to our own computer. 

Iwans-Mac:~ iwanhoogendoorn$ git clone https://github.com/vmware/pyvmomi.git

Create a new user in vCenter to make python calls to vCenter Server

When we are executing scripts agains vCenter Server it is the best practice to have a special account for this purpose. Therefore we need to create a new account in vCenter and assign this account to the correct role (preferably Administrators). I have use the following:

UN = pyvmomi-user
PW = VMware 1!

Execute one of the sample Python scripts in the sample directory 〈getallvms py〉

Our first script that we are testing our is the getallvms.py script that is located in the sample folder. 

Iwans-Mac:pyvmomi iwanhoogendoorn$ cd sample

As you can see we have gathered a list of all the VM's and we are using a ready-to-use script that was in the sample directory. The information that we see is Name, Path , Guest and State!

Alter the getallvms.py script to only show virtual machine names

But what if we only want to VM names? Then we can alter the script a little. First we copy the script so we have a second script that we can alter and leave our original script unharmed. 

Iwans-Mac:sample iwanhoogendoorn$ cp getallvms.py getallvms-only.py 

Iwans-Mac:sample iwanhoogendoorn$ ls
root ##b##getallvms-only.py##!b##       getallvms.py            poweronvm.py

Then alter the script: 

Iwans-Mac:sample iwanhoogendoorn$ nano getallvms-only.py
getallvms-only.py - Original code snippet
summary = vm.summary
   print("Name       : ", summary.config.name)
   print("Path       : ", summary.config.vmPathName)
   print("Guest      : ", summary.config.guestFullName)
   annotation = summary.config.annotation
   if annotation != None and annotation != "":
      print("Annotation : ", annotation)
   print("State      : ", summary.runtime.powerState)
   if summary.guest != None:
      ip = summary.guest.ipAddress
      if ip != None and ip != "":
         print("IP         : ", ip)
   if summary.runtime.question != None:
      print("Question  : ", summary.runtime.question.text)
   print("")
getallvms-only.py - Replaced with this code snippet
summary = vm.summary
   print("Name       : ", summary.config.name)
#   print("Path       : ", summary.config.vmPathName)
#   print("Guest      : ", summary.config.guestFullName)
#   annotation = summary.config.annotation
#   if annotation != None and annotation != "":
#      print("Annotation : ", annotation)
#   print("State      : ", summary.runtime.powerState)
#   if summary.guest != None:
#      ip = summary.guest.ipAddress
#     if ip != None and ip != "":
#         print("IP         : ", ip)
#   if summary.runtime.question != None:
#      print("Question  : ", summary.runtime.question.text)
   print("")

Execute getallvms.py again

We have now "hacked" into the script, but there are also some other scripts available on the internet that we can try.

Try another script that provides information about VM's 〈py–vminfo.py〉

After searching for some scripts that can provide me information about specific VM's I came across this script (py-vminfo.py).

When executing the script I got an error: 

Iwans-Mac:python-vmstats-master iwanhoogendoorn$ python py-vminfo.py -s 10.11.11.215 -u pyvmomi-user@sso-iwan.local -p VMware1! -m CSR-1000V-R1
root ##b##Could not connect to the specified host using specified username and password##!b##

I was pretty sure that I was using the correct username and password... After asking around and contacting the creator of the script we both discovered that this had to do with the way the script was trying to connect to the vCenter Server.

I have crosschecked the "getallvms-only.py" script that WAS WORKING for me and the "py-vminfo.py" script that WAS NOT WORKING and I discovered some change in the "SmartConnect" part.

Newer versions of vSphere have required certificate verification and a warning was always thrown up... It looks like perhaps this warning turned into a hard STOP unless you provided some sort of SSL override to say "It's OK I know this cert is self sign - for example - but carry on" This is now taken care of the new SSL code part that I added in the script.

More information regarding this can be found here.

I altered the script a bit with some new parts.

py-vminfo.py - Original code snippet:
try:

                              sslContext=context)  --> added

After I added in the new parts I tested the script again,

As a bonus another script to test with 〈vminfo_quick.py〉

After searching for more scripts to retrieve information about VM's a also came across this script(vminfo_quick.py).

I got an error after I executed the script. 

Iwans-Mac:sample iwanhoogendoorn$ python vminfo_quick.py -s 10.11.11.215 -u pyvmomi-user@sso-iwan.local -p VMware1!
Traceback (most recent call last):
  File "vminfo_quick.py", line 19, in <module>
    from tools import cli
ImportError: No module named tools

Apparently the script is referring to a module "tools". In the initial git clone that I used it did not contain a "tools" directory where "cli" is in as well. So I needed to clone / download this "tools" folder as well and place it in the sample directory.

I used "Github downloader" to download complete github folders. 

Iwans-Mac:Downloads iwanhoogendoorn$ chmod 777 github-downloader.sh

I moved the tools folder into the sample folder and run the script again ... 

Iwans-Mac:sample iwanhoogendoorn$ python vminfo_quick.py -s 10.11.11.215 -u pyvmomi-user@sso-iwan.local -p VMware1!
root ##b##Unable to connect to host with supplied info.

I received another error, and I suspected that this had something to do with the SSL self signed certificate handeling so I started altering the script.


vminfo_quick.py - Original code snippet:
service_instance = connect.SmartConnect(host=args.host,
                                            user=args.user,
                                            pwd=args.password,
                                            port=int(args.port))
vminfo_quick.py - Replaced with this code snippet:
#

                                            sslContext=context) --> added

I tested the script again.
