Automated ESXi Installation with a USB Network Adapter using Kickstart

02.01.2023 by William Lam // 4 Comments

I have been working with the Project Keswick team for quite some time now, which is an OCTO project is lead by my good friend Alan Renouf, who is doing some really innovative work with ESXi at the edge and application deployment using a desired state engine.

Recently I had met with the team to discuss some of the options for their automated deployment which uses the tried and true ESXi scripted installation aka ESXi Kickstart. One thing that I had shared was just how powerful the %pre section within the kickstart is and can be used to redefine or update the original kickstart based on your installation criteria. For example, you could pull down external configuration files and determine at runtime to decide how you want to configure your networking to even fully bootstrapping a local vSAN datastore and this would all happen prior to ESXi installer starting. I have used the %pre section numerous times as a customer and also demonstrated in my USB-to-SDDC project which has also been an inspiration for the Project Keswick team.

One very cool capability that Project Keswick is enabling is the integration of the popular USB Network Native Driver for ESXi and one challenge they had faced with automating an ESXi installation when only a USB network adapter was available is additional configuration that must be setup before the installer can begin. They shared their solution and thought this would be a good blog post topic, especially as I know many folks use the USB Network Native Driver for ESXi in their homelab and if you wish to automate the installation, the solution shared from the team could help.

ESXi with Intel Arc 750 / 770 GPU

I have to say, the @IntelGraphics team does a very nice job on their packaging!

Look forward to kicking the tires on their new Arc GPUs, luckily this fits nicely in the Intel 12 Extreme NUC (Dragon Canyon) ๐Ÿ˜ pic.twitter.com/DHTC93pzmc

I recently had the opportunity to play with one of Intel's Arc 7 series discrete GPU (A750), which is part of the new Intel Arc desktop graphics product line, that was just released last Fall. While the primary audience for the Intel Arc graphics is for creators and desktop gaming, I was really interested in its applicability for a vSphere-based environment which also has a number of interesting use cases for graphics from Virtual Desktop Infrastructure (VDI), video transcoding/rendering, AI/ML, Kubernetes, general purpose graphics acceleration and even basic gaming to name a few.

While there are many GPU options in the market for vSphere, depending on your needs and budget, the new Intel's new Arc 7 series could be a nice modern option as it is touted to be both price and performance competitive with other offerings within the market.

How to recover ESXi installed on USB device after disabling vmkusb module?

01.12.2023 by William Lam // Leave a Comment

I have to say, this is one of the more interesting challenges that I have come across in quite some time. A user was looking for assistance after they accidentally disabled the vmkusb module, which is the USB driver for ESXi and allows it to communicate with USB devices that are connected to the system.

The vmkusb module also plays a very critical role if you have ESXi installed on a USB device, as the driver is required for proper functionality such as being able to save the ESXi state and configurations to the USB device. So what happens when you disable the vmkusb module and you reboot the ESXi host, which is also installed on a USB device?

Well, everything continues to work including VMs since ESXi by design runs in memory after the initial boot from the USB device. However, any configuration changes made after that is lost after a system reboot including the attempt to re-enable the vmkusb module since ESXi is unable save any of the settings to the USB device. Fortunately, I was able to help the user out as I had a few ideas on how we could fully recover from this type of scenario and hence the blog post.

Hopefully a lesson can be learned here, do not make changes or disable things that you are not familiar with ๐Ÿ™‚
