ESX Server 1.0 - Trip down memory lane

by // 10 Comments

I recently had a bit of VMware Nostalgia and for the past several weeks, I have been working on a personal skunk works project in trying to locate all major ESX and ESXi releases over the past 22 years including ESX Server 1.0 which was released by VMware back in 2001!

To my surprise, finding a digital copy of ESX pre-2.0 (1.0 & 1.5) was much harder than I had expected. Back in those early days, software was not commonly distributed over the internet like it is today, instead it was sent to vendors to create physical CD/DVD discs, which was then shipped to customers and partners. I had also reached out to many tenured folks at VMware who were still around from the early days, but each response lead to another set of folks and it typically either went in a circle or to a dead end. This was turning into an archeological hunt.

I decided to give it one more shot and I pinged John Arrasjid aka VCDX #1 and after a bit of searching, John actually found a pristine copy of ESX Server 1.0, still sealed in the box! Given how difficult it was to locate a 1.0 copy of ESX, we thought it was worth opening up and to preserve this VMware history by creating a digital ISO image, so that I could then share the experience of installing ESX 1.0 with the broader VMware community.

How to enable passthrough for USB Network Adapters claimed by ESXi CDCE Driver?

by // 12 Comments

As part of vSphere 7.0, ESXi now ships with a USB CDCE (Communication Device Class Ethernet) driver which can benefit customers with SB network adapters that support the CDCE specification as shared in this blog post HERE. This can especially be useful for those running a VMware Homelab where the onboard network adapter may not be supported and using a CDCE USB network adapter would allow you to install ESXi.

When a CDCE-supported USB network adapter is connected to an ESXi host, it will automatically be claimed by the CDCE driver as shown in the screenshot below.


If you are planning to use the USB network adapter for VMkernel traffic, then there is no workflow change like any other physical network adapter. However, if you intend to passthrough the USB network adapter to a VM, then you may find that it is not working as expected.


The reason for this is that ESXi has already claimed the USB device, assuming you wish to use it for VMkernel traffic. To change the behavior for a particular CDCE-supported USB network adapter, we just need to apply a USB Quirk which tells ESXi to ignore this adapter.

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.
