Quick Tip - Suppress in-guest VMware Tools update notifications

by // Leave a Comment

If you have a Virtual Machine that has VMware Tools installed and a newer version is available, end users within the guest operating system might see a status bar notification with the following message:

A newer version of Tools is available for this VM

Most organizations already have a well defined process in rolling out new software updates including VMware Tools, so while the in-guest notification about a new version of VMware Tools can be useful for some, it either not applicable or adds unnecessary distractions for their end users. I recently learned that you can disable these in-guest notification by applying one of the following configurations:

Windows

  • Disable VMware Tools notification at system Level
    • Set the following registry key: HKEY_LOCAL_MACHINE\Software\VMware, Inc.\VMware Tools\ShowTray to 0 (REG_DWORD)
  • Disable VMware Tools In-Guest Notification at the user Level
    • Set the following registry key: HKEY_CURRENT_USER\Software\VMware, Inc.\VMware Tools\ShowTray to 0 (REG_DWORD)

Feedback has already been acknowledge to add this information to the official VMware Tools documentation and that it may be possible to configure these notification settings using the VMware Tools configuration file (tools.conf) in the future, further simplifying any configurations related to VMware Tools.

Quick Tip - Using PowerCLI to query VMware Tools Configuration at scale 

by // Leave a Comment

One of the most powerful and versatile VM management capability in vSphere is the Guest Operations API, providing a rich set of operations from transferring files to/from the guest to running commands directly on the guest as if you were logged in!

An easy way to consume the Guest Operations API is via PowerCLI and using the Invoke-VMScript cmdlet, which I have extensively written about, showcasing all the creative ways this can be used to solve various automation challenges.

I recently came across a Reddit thread where the OP wanted to check to query for a specific VMware Tools configuration as part of the vSphere Security Configuration Guide and was looking for some help as logging into each and every system did not seem like a good idea, which it is NOT! 🙂

Any time you have a use case where you need to scale a specific operation (reading or writing) a change, you should consider Guest Operations API, you can easily use a single API to perform this operation at scale!

New detailed GuestOS data in vSphere 8.0 Update 2

by // 5 Comments

Your workloads are constantly changing both from an application standpoint but also the underlying guest operating system (GuestOS) including patches and upgrades. While many organizations have a change management database (CMDB), it can still be a challenge to true up that information from when the workload was first deployed to what it is currently running.

Back in 2019, VMware enhanced VMware Tools to make it easier to identify applications and processes that was running within a VM and this also provided a programmatic way for retrieving this inventory information which could then be fed back into their CMDB.

Applications are not the only things that change inside of a VM, the GuestOS probably receives the most updates (patches/upgrades) and being able to accurately inventory this information without relying on an in-guest agent is still a challenge for many.

In vSphere 8.0 Update 2, we have enhanced the available GuestOS data using VMware Tools and we have also made it easier to inventory and collect this information even when the VM has been powered off.
