VMware vSphere Upgrade Planning

It’s that time – VMworld has come and gone.  Now there are new ideas and new releases that need explored.    No better time to start your VMware vSphere Upgrade Planning!

Taking the time to plan your upgrade can lead to better results.  This can lead to less hassle and stress for you as well as a smoother process for your organization.  It is time well spent!

Continue reading for a review of the tools that can help you upgrade like a pro!

VMware Product Lifecycle Matrix – One of the first things to understand is how much time do you have on your current products until they are out of support.  Do you know how long your vCenter and vSphere versions are supported?  What about other VMware products?  The Product Lifecycle Matrix can help you figure that out.

Changes to the VMware Product Lifecycle Matrix

I love this time of year!  The weather (in Ohio anyway) is starting to turn cooler.  VMworld is right around the corner – and lots of VMware Admins are starting to plan upgrades!

VMware has made a number of improvements to the tools that you use to plan your next upgrade!  This is the first blog post in a series that will review these changes.


This week, I’ll highlight the updates to the VMware Product Lifecycle Matrix.  Instead of telling about them – I’ll show you!

Check back next week as we review another planning tool!

What is VMware Skyline?

VMware Skyline is more than just a single tool. There are 3 different tools under the Skyline name. Each of them has a distinct purpose and use case.  I have put together a few  videos that might help you learn more!

I recommend you start with the Skyline Overview

vCenter Server Security Advisory – VMSA-2021-0010

Last week, VMware released information on a critical issue affecting Plug-ins on vCenter Server.  VMware recommend customers patch or implement the workaround as soon as possible.

The vSphere Client (HTML5) contains a remote code execution vulnerability due to lack of input validation in multiple plug-ins in vCenter (some of which are enabled by default). VMware has evaluated the severity of this issue to be in the Critical severity range with a maximum CVSSv3 base score of 9.8.  The full notice (including list of plug-ins) can be read at https://www.vmware.com/security/advisories/VMSA-2021-0010.html

This affects certain versions of vCenter Server (Windows and the VCSA alike).  The work around is to disable the affected plug-ins in vCenter – KB 83829.  This does impact management and is considered a short-term stop gap.

Notes From The Field

vSphere 7 Update 1 introduced the vSphere Cluster Services (vCLS). This change has abstracted the Distributed Resource Scheduler (DRS) and High Availability (HA) functionality from vCenter.  These functions are now controlled by a set of small virtual machines.  You will not see them in the inventory view; but you may see them on a datastore or in other reports that show running VMs.  These VMs are named vCLS – or vCLS(x).  You don’t need to manage them; but it is good to understand what they are.  You can read more on the YellowBricks blog.

When installing vSphere 7 on a number of older processors you may see a warning that this processor will be deprecated soon.  The affected processors are all in or near End of Life or End of Support status by their respective manufacturers.  You can see the full list of AMD & Intel CPUs in VMware KB 82794.

The vSphere 7 Security Configuration guide has been updated and is now available.

Finding MAC Address of rogue IP on Dell PowerConnect

Welcome to the inaugural post in my Before I Forget series.  I”ll be using this category to document bits of knowledge that I don’t want to lose.   We all perform steps that are only needed once in a while; but when you need them – you really need them!  I know they will help me. I hope they benefit others as well…

Rogue IP Addresses can mess up the day

In this case, I figured out how to find the MAC Address of an errant device on my network using it’s IP Address.  My Homelab uses a Dell PowerConnect 6248 at it’s core.  It is an older; but quite serviceable switch.

I received an alert the other day that one of my Wireless APs had gone offline.  I went through a few troubleshooting steps and found that while I could ping it’s statically assigned IP – it did not show up in the Ubiquiti management console. I restarted the device but it did not resolve the issue.

Obviously something was responding on that IP Address; but I didn’t know what it was.  This particular subnet was wired-only, so I knew I could track it down.  A seasoned network engineer I am not; but was able to figure it out within a few minutes.

Update the External URL when you replace the Horizon Connection Server Certificate

 I have finally setup a certificate authority in my lab and am working on replacing self-signed certs. This week I was working on my Horizon Connection server.

When you make changes to the SSL Certificate on your Horizon Connection Server(s), you may see an error message similar to this:

Server's certificate subject name does not match the server's External URL.  Server's certificate is not trusted.

When you first install the Connection Server, it uses the hostname of the server as the “External URL”.  If this does not match the URL you will publish for your users, a small change needs to be made in the configuration of the Connection Server.
