Creating custom ESXi images using vSphere Lifecycle Manager (vLCM) UI and PowerCLI cmdlets for vSphere 8

11.22.2022 by William Lam // 26 Comments

I have started to use vSphere Lifecycle Manager (vLCM) more and more, especially after upgrading to vSphere 8 as it will be the primary lifecycle management solution going forward for both vSphere image and configuration management.

The other reason for using vLCM is that vSphere Update Manager (VUM) baselines have also been deprecated in vSphere 8 and while you can still use it for now, it should not come as a surprise that VUM and its functionality will be removed in the future and all of its workflows including the use of vSphere Image Builder should also be transitioned over to using vLCM.

One of the most common and basic workflow for customers today is creating custom ESXi images (ISO or Offline Bundle) that includes additional ESXi drivers. Since vLCM is probably new to most folks (including myself), I wanted to share how you can create your own custom ESXi images using both the vLCM UI (which can be a bit non-intuitive) as well as the new PowerCLI cmdlets that was jus released today as part of PowerCLI 13.0 release that adds support for both vLCM and vSphere 8!

How to delete an ESXi component in vSphere Lifecycle Manager (vLCM) depot?

11.16.2022 by William Lam // 8 Comments

vSphere Lifecycle Manager (vLCM) allows users to upload an ESXi component into its depot using the Import Updates operation in the vSphere UI, but deleting an ESXi component from the vLCM depot is currently not possible when using the vSphere UI.


However, using the vLCM REST API we can delete an ESXi component from the vLCM depot with the Settings Depots Offline APIs. To demonstrate these specific vLCM REST APIs, I will be using PowerCLI (Connect-CisServer) but you can also use the vLCM REST API directly via any REST Client.

Using vSphere Lifecycle Manager (vLCM) to remediate Nested ESXi host with CPU on the host is not supported 

10.24.2022 by William Lam // 4 Comments

If you are running a Nested ESXi VM on top of a physical ESXi host that does not have a supported CPU and you are using vSphere Lifecycle Manager (vLCM), the pre-check and/or remediation will fail due to the following error:

The CPU on the host is not supported by this image


The solution is actually quite simple and is similiar to what you had to do for your physical ESXi host by adding the ESXi kernel boot option allowLegacyCPU=true to successfully boot and install ESXi as recently explained in this blog post. To emulate this setup, I am using my trusty 2011 Apple Mac Mini which is running ESXi 8.0 with the kernel boot option and it is then running a Nested ESXi 7.0 Update 3g VM.
