Quick Tip - Automating ESXi 8.0 install using allowLegacyCPU=true

by // 3 Comments

For those looking to install ESXi 8.0 but have an unsupported CPU, the following kernel boot option allowLegacyCPU=true can be added which would bypass the installer pre-check as shown in the screenshot below.

When the ESXi installer bypass happens, instead of an error which forces you to reboot, you will get a warning message and user must acknowledge they understand they are using an unsupported CPU and then continue with the installation.

Note: For more information, also checkout my vSphere 8 Homelab considerations blog post for more tips and tricks.

For an interactive installation of ESXi, the additional acknowledgment is not an issue but for an automated installation of ESXi using Kickstart, this can be a problem since you are still required to manually hit enter before the installation actually begins. The question from a couple of my readers, is there a workaround for this?

Using vCenter Converter 6.3 with vSphere 8 or VMware Cloud on AWS (VMC-A)

by // 5 Comments

Since the announcement that vCenter Converter was re-returning, customers have been looking forward to the day that vCenter Converter would be an officially supported product again. Luckily, folks did not have to wait long from the early beta almost a month ago and just a couple of days ago, vCenter Converter 6.3 has officially GA'ed!

The goal of this initial vCenter Converter release was to bring functional parity with the last supported release, updated development and security practices and a few minor enhancements including some new Guest Operating Systems and vSphere 7.0 support. The team still has a ton in store for subsequent releases and if there are certain features you really want to see, feel free to leave a comment and I will be sure to share it with PM/Engr team.

With that said, I have also been getting a lot of questions from customers interested in using Converter to migrate workloads to VMware Cloud on AWS (VMC-A), especially as they think about modernizing and consolidating their Datacenter infrastructure. While, VMware Cloud on AWS as a destination will be in scope for the next release, I was curious on whether it would work given that vSphere 7.0 support was added to latest vCenter Converter release.

You know what happens when I get curious ... I just have to try it out! 😅

Enabling vSAN 8 Express Storage Architecture (ESA) using Nested ESXi

by // 13 Comments

To get the full benefits and support of the new vSAN 8 Express Storage Architecture (ESA), you will need modern hardware from the official vSAN ESA Ready Node HCL. However, from an education and learning point of view, you may want to explore some of the VSAN ESA workflows and easiest way to do that, well you probably know the answer .... it is using Nested ESXi of course!

With my recently published vSphere and vSAN 8 Lab Deployment Script, you can use that as the base and the Nested ESXi 8.0 IA Virtual Appliance to setup vSAN 8 ESA using virtual hardware 😀


There are only a couple of things to be aware of prior to setting up vSAN ESA using Nested ESXi.
