How to retrieve the default VM hardware configuration for a specific Guest OS in vSphere?

by // Leave a Comment

Have you ever wondered how or where the vSphere UI generates the default Virtual Machine hardware configuration after selecting a specific Guest OS during the VM creation wizard?


The answer is simply by asking the vSphere platform 🙂 and of course this is provided as an API for any client to consume including our own vSphere UI.

This is a topic I had written about back in 2013 here and here, which demonstrates how to use the EnvironmentBrowser API to query for the list of supported Guest OS and Virtual Hardware Compatibility. In addition to this information, we can also ask the vSphere platform on what are the default hardware configuration for all supported Guest OS using the QueryConfigOption API.

Potentially interesting VMware Homelab Kits for 2022

by // 32 Comments

I am always on the lookout for new and interesting hardware platforms that can benefit the VMware Homelab Community. In the month of January, there were a number of new announcements that I had been following including news from the Computer Electronic Show (CES) but also a couple of product releases from vendors that I had not heard of before until most recently.

While the global silicon shortage is still a very real challenge, here are some of the new and upcoming hardware platforms that I think could potentially be interesting for VMware Homelabs in 2022. The list below is not exhaustive and I primarily focused on platforms that offers a unique or interesting capability based on the various requirements that I have heard from the community over the years. As an example, I know some of you have expressed interests in platforms that are capable of supporting full length discrete GPU for VDI, AL/ML and Kubernetes-based workloads to a platform that can enable more advanced networking features with multiple onboard network adapters.

If there are other platforms that I or the community should definitely keep an eye out for in 2022, feel free to leave a comment with a pointer to the reference. I will periodically update this article with additional new systems, so definitely bookmark this page and check back frequently.

Considerations for future vSphere Homelabs due to upcoming removal of SD card/USB support for ESXi

by // 16 Comments

In case you have not heard the news, VMware had recently published a new knowledge base article (KB 85685) outlining details for the future removal of SD card/USB as a standalone boot device for ESXi.

If you have not read the KB, please take a few minutes and carefully read the article, especially as you think about future hardware upgrades and purchases.

There has certainly been no shortage of discussions and debates since the publishing of the VMware KB. One topic that I know many of you have been wondering and asking about is what is the impact to vSphere Homelabs? This was something that had already crossed my mind after I first read the KB and I was thinking about this a bit more this week and specifically some of the potential options that are available to customers right now but also some of the considerations you may want to account for in with future homelab upgrades.
