ESXi configstorecli enhancement in vSphere 8.0 Update 1

by // 1 Comment

The ESXi configstorecli was introduced back in vSphere 7.0 Update 1 and provides access to the ESXi ConfigStore which responsible for centrally managing all configurations for an ESXi host instead of relying on different methods including a variety of configuration files, I highly recommend reviewing this refresher article HERE if you have not heard of the configstorecli before. The ESXi ConfigStore is also the underlying infrastructure that powers the new vSphere Configuration Profile feature which is also part of the vSphere Lifecycle Manager (vLCM) solution.

For those who currently or plan to automate ESXi installations using Kickstart, I wrote an article HERE last year on how to start converting some of your existing automation into using the new ESXi configstorecli, which is another article I recommend folks take a look if you have no already.

One of the challenges that I personally found when using configstorecli was purely figuring out the overall schema for the different components, groups and keys that are available. While I have demonstrated how to traverse the configstore in this blog post HERE, I still found experience less than ideal. I would have liked a bit more of an iterative exploration of the configstore itself and rather than showing the entire schema, I could slowly expect each node as configstore is a stored as a JSON document.

ESXi on Intel NUC 13 Pro (Arena Canyon)

by // 35 Comments

A new year means a new Intel NUC with the latest generation of processors from Intel.


Today, Intel has launched the new Intel NUC 13 Pro, previously codenamed Arena Canyon NUC, which incorporates the latest Intel 13th Generation Raptor Lake CPU mobile processors and delivering that in the classic 4x4 Intel NUC form factor that many in the VMware community are quite familiar with.

At first glance, the Intel NUC 13 Pro looks exactly the same as the previous Intel NUC 12 Pro generation. In fact, the only visible difference on the outside between the 12th and 13th Generation Intel NUC Pro is that the Intel NUC 13 now has a new etched Intel NUC logo that is located on the top of the case on the lower left as shown in the screenshot above. Obviously, the changes with the Intel NUC 13 Pro is from within, so lets now take a closer look at the newest Intel NUC Pro and what it has to offer from a VMware Homelab perspective.

Quick Tip - Enabling ESXi Coredumps to be stored on USB

by // Leave a Comment

I was recently working with Engineering to reproduce an issue which causes an ESXi PSOD (Purple Screen of Death) and I wanted the generated ESXi coredump to simply write to the USB device, which I could easily grab.

As of ESXi 7.x, I know we had removed a few of the old ESXi kernel boot options for allowing ESXi to store coredumps on a USB device and the using the ESXi kernel boot option allowCoreDumpOnUsb=TRUE should now be used, however I was struggling to get it to work.

Since I was using a debug version of ESXi, I needed to install ESXi from scratch and I thought I could simpply add the required kernel option, as shown in the screenshot below, and I had assumed it would automatically configure the ESXi coredump file to be stored on the VMFS-L volume residing on the USB device.


After a couple of attempts, I finally realized that this particular ESXi kernel boot option, is literally that, a boot option that is only applicable after the initial ESXi installation. 🤦 Unlike other ESXi kernel boot options which can be used during the initial installation which would apply certain configuration changes, this setting applies after ESXi has been installed. Once I appended the setting, the ESXi coredump file was created in the VMFS-L volume and I was then able to reproduce the issue and generate vm-support bundle that included the coredump!
