VMware Tools Community Module Introduction

VMware Tools is a collection of in-guest drivers and agents that optimize performance and increase the manageability for VMs within vSphere environments. Guess what, PowerCLI provides a way to automate the management of the VMware Tools lifecycle! Even better, a new module was recently entered into the PowerCLI Community Repository to help make those management tasks even easier than before!

The module includes a collection of over 10 different advanced functions! These include the following:

Get-VMByToolsInfo Retrieves the virtual machines with specified VMTools info.
Get-VMToolsGuestInfo Retrieves the guest info of specified virtual machines.
Get-VMToolsInfo Retrieves the VMTools version and build number info of specified virtual machines.
Get-VMToolsInstallLastError Retrieves the error code of last VMTools installation on specified virtual machines.
Get-VMToolsUpgradePolicy Gets the VMTool’s upgrade policy of specified virtual machines.
Invoke-VMToolsListProcessInVM Lists the running processes in the virtual machine.
Invoke-VMToolsUpgradeInVMs Upgrades VMTools to the version bundled by ESXi host.
Invoke-VMToolsVIBInstall Installs VMTool VIB in specified ESXi hosts.
Set-VMToolsUpgradePolicy Sets the VMTool’s upgrade policy to either “manual” or “upgradeAtPowerCycle” of specified virtual machines.
Update-VMToolsConfInVM Updates the tools.conf content in guest OS.
Update-VMToolsImageLocation Updates the /productLocker link in an ESXi host directly

Let’s take a look at how to get started using this great module.

Accessing the Module

There are a couple ways to get access to this great module, all of which go through the PowerCLI Community Repository. One of the easiest ways is to load up the repository’s page, click on the green ‘Clone or download’ button, then clicking on ‘Download ZIP’. This downloads the entire contents of the repository to your local system.

Download PowerCLI Community Repository to Local System

Once the download is complete, unzip the files and browse to the ‘Modules’ directory. We are now going to copy the VMToolsManagement folder and paste it in one of the directories that are listed in the PSModulePath variable. Doing this allows the module to be available for automatic importing by your PowerShell session!

By default, the PSModulePath variable contains the following directories:

  • $home\Documents\WindowsPowerShell\Modules
  • $pshome\Modules

In my environment, I have placed the module in the first of the above options. This is also where my PowerCLI modules are available.

One item to keep in mind, the ‘Update-VMToolsImageLocation’ does require the usage of an ESXi host’s SSH service. Therefore, the SSH service on the ESXi host must be running as well as having an SSH library on your local system.

Module Usage

There are a couple functions that make it really easy and straight forward to retrieve VMware Tools information from VMs in the environment. These functions accept VM input from either direct VM parameter usage or pipeline. Here’s example output from the following advanced functions:

  • Get-VMToolsInfo
  • Get-VMToolsGuestInfo
  • Get-VMToolsInstallLastError

Example of retrieving VMware Tools information from a VM

There’s a very versatile function which allows us to query our environment for specific information about the state of VMware Tools on our VMs. This advanced function is ‘Get-VMByToolsInfo’ and has a couple nice parameters to help us out. The first parameter is ‘Tools Version’ which displays only VMs which contain the specified version. The next parameter is ‘ToolsRunningStatus’ which displays only VMs which are of the specified running state. The last parameter is ‘ToolsVersionStatus’ which displays only VMs that are of a certain status. The last two parameters feature tab complete functionality for each of their inputs.

Here are examples of a couple commands I ran within my environment:

Let’s move on past simply retrieving information now. There are two functions which allow us to both retrieve and manage the upgrade policy for VMs. This can be done with the following advanced functions:

  • Get-VMToolsUpgradePolicy
  • Set-VMToolsUpgradePolicy

The Set-VMToolsUpgradePolicy allows us to modify the upgrade policy for a VM with the ‘UpgradePolicy’ parameter. This parameter also allows for tab completion between the two accepted policies. Here’s an example of those two functions in action:
Example of configuring the VMware Tools Upgrade Policy for a VM

We also have the ability to change the VMware Tools logging level. This is something that is normally done internally on the guest system but, through the magic of PowerCLI, we can now do this remotely with the ‘Set-VMToolsConfInVM’ advanced function! This function features a ‘LogLevel’ parameter which handles the changing of log level. Tab completion is available for this parameter as well. Additional information about configuring these settings can be found in KB 1007873. One note about this function, be aware of what the permissions are on the local system. Certain OSes can be touchy about modifying files within the folders where these configuration files are held.

Example of modifying the VMware Tools logging level

This module wouldn’t be complete without the ability to also upgrade a system’s VMware Tools too! This is accomplished with the ‘Invoke-VMToolsUpgradeInVMs’ advanced function. Here’s an example of it in action:
Example of upgrading the VMware Tools on a specified VM

Lastly, there are two functions that help to manage VMware Tools’ accessibility directly from ESXi hosts! The ‘Update-VMToolsImageLocation’ advanced function allows us to change the location of where VMware Tools are stored for ESXi hosts. For example, we could store the VMware Tools and floppy files on a datastore instead of the local system! One other nice feature of this function, there is no reboot required for the configuration update to go into effect. Then, there is the ‘Invoke-VMToolsVIBInstall’ advanced function. This function allows us to install and make available updated versions of VMware Tools out of the normal ESXi update lifecycle.

Here’s an example of updating an ESXi host with a newer version of VMware tools by way of a VIB:
Example of updating the VMware Tools version that's available on the ESXi host

Summary

The VMToolsManagement module is a terrific resource for any administrator needing to get quick and easy access to manage the lifecycle of VMware Tools in their environment. This module comes packed with over 10 different advanced function to handle a majority of the tasks admins face.

Head out to the PowerCLI Community Repository, download it, and let us know in the comments how you’re putting it to use in your environment!

Updating the VMware PowerCLI Community Repository!

PowerCLI + GitHub
If you’ve ever tried searching for a script or a module before, you know it’s not the easiest thing to accomplish. This sentiment has been coming up more and more as of late. There’s a ton of amazing PowerCLI scripts and modules, PowerActions scripts, DSC resources, and so forth contributed by the community and openly available.

The VMware PowerCLI Community Repository is a central location where anyone can contribute their own resources. The repository features a Principles of Operations document to help guide contributors along the process of using, creating, and updating resources which are contained within the repository.

This community repository will also feature several community members as board members. As part of the board, they will be asked to help maintain the repository with tasks such as testing and providing feedback on all submitted resources, communicating with other board members in order to approve pull requests, and continuing to be good community advocates of PowerCLI and the community repository.

I’d like to thank and welcome the following board members:
Josh Atwell (Community Member)
Luc Dekens (Community Member)
Jonathan Medd (Community Member)
Alan Renouf (VMware)
Kyle Ruddy (VMware)
Rynardt Spies (Community Member)

Want to Change VM Component Protection Settings via PowerCLI? Now you can!

I had a VMware Senior Systems Engineer reach out to me yesterday asking on a customer’s behalf, if there were any PowerCLI cmdlets that could change VMCP settings.

*** If you are not familiar with VM Component Protection, I suggest you take a look at this blog post written by my co-worker Matt Meyer, which describes in detail what VMCP is and what each setting does: https://blogs.vmware.com/vsphere/2015/06/vm-component-protection-vmcp.html ***

I knew that we didn’t have any cmdlets for this yet so the next step for me was to Continue reading

New PowerCLI Example Scripts Github Repository is now Live!

PowerCLI-Github.png

Code is everywhere, and I’m sure there are duplicates of code that we’ve posted on the blog or personally, strewn throughout the interwebs. The idea behind opening this repo is to have a location where we can paste code, functions, and modules from the blog posts as well as anything else cool we come up with.

 

The PowerCLI-Example-Scripts repo runs under the Tech Preview license, which you can read on the github site, describes the condition and terms of use of this code. We encourage everyone to feel free to add to, modify, and send through pull requests so that we can also maintain this as more of a community repo. Just note that there are only a few of us as admins on the repo so it may take a little time to validate and accept anything that comes our way.

We hope you enjoy and look forward to sharing more in this repo, along with seeing what the community sends our way. Happy Friday!
