ESXi on Intel NUC 12 Enthusiast (Serpent Canyon)

by // 16 Comments

The Intel NUC Enthusiast product line is typically geared towards content creators and gamers. These Intel NUCs, include Skull Canyon, Hades Canyon and Phantom Canyon, are all equipped with an onboard discrete GPU.


The Intel NUC 12 Enthusiast, codenamed Serpent Canyon, is the latest offering in this product line and it is also the first Intel NUC that includes both an Intel CPU and an Intel GPU, which is based on the latest Intel Arc graphics.

Within the VMware Community, both the Skull Canyon and Hades Canyon were extremely popular due to the additional graphics and storage capabilities at the time. With my recent updated findings on iGPU passthrough for recent Intel NUCs with ESXi and the combined compute and graphics solution from this latest offering from Intel, Intel NUC 12 Enthusiast can make for a pretty powerful and capable VMware setup!

Let's take a closer look at the new Intel NUC 12 Enthusiast from a VMware point of view!

Updated findings for passthrough of Intel NUC Integrated Graphics (iGPU) with ESXi

by // 48 Comments

While searching for drivers for another Intel NUC platform, I saw that Intel had recently published new graphic drivers for Linux including support for their new Intel Arc GPUs. This of course got me curious on wondering whether this would help at all with the issues regarding passthrough of the integrated graphics (iGPU) for recent Intel NUCs? 🤔

As a refresher, starting with the 11th Gen Intel NUCs, passthrough of the iGPU on Windows had stopped working and would result in the infamous Windows Error Code 43 and even worse on the 12th Gen Intel NUCs, Windows would simply BSOD after the initial reboot. The behavior is also simliar for Linux operating systems, while it better handles the issue by not crashing the OS, iGPU passthrough is also not functional for Linux systems.

To be honest, I had low expectations these new Linux graphic drivers would behave any differently, but I decided for the sake of persistency that I would give it one more go. I had access to both an Intel NUC 12 Extreme (Dragon Canyon) and Intel NUC 12 Pro (Wall Street Canyon), both of which included recent Intel iGPUs.

🤯🤯🤯 is the only way I could describe what I had discovered after my testing!

Using vSphere Lifecycle Manager (vLCM) to remediate Nested ESXi host with CPU on the host is not supported 

by // 4 Comments

If you are running a Nested ESXi VM on top of a physical ESXi host that does not have a supported CPU and you are using vSphere Lifecycle Manager (vLCM), the pre-check and/or remediation will fail due to the following error:

The CPU on the host is not supported by this image


The solution is actually quite simple and is similiar to what you had to do for your physical ESXi host by adding the ESXi kernel boot option allowLegacyCPU=true to successfully boot and install ESXi as recently explained in this blog post. To emulate this setup, I am using my trusty 2011 Apple Mac Mini which is running ESXi 8.0 with the kernel boot option and it is then running a Nested ESXi 7.0 Update 3g VM.
