Passthrough of Intel Iris Xe Integrated GPU on 11th Gen NUC results in Error Code 43

by // 49 Comments

I recently ran into an issue after enabling ESXi passthrough of the new Intel Iris Xe Integrated GPU (iGPU), which is available with the latest Intel 11th Gen Pro (Tiger Canyon) NUC and SimplyNUC Topaz. After installing the latest Intel Graphics Driver and rebooting the Microsoft Windows 10 (20H2) VM, I noticed Microsoft Device Manager would show the iGPU device with the following error message:

Windows has stopped this device because it has reported problems. (Code 43)


Unfortunately, this generic error message was not very useful in identifying the underlying issue. I was hoping the process was going to be seamless like it was for enabling passthrough of the iGPU in Intel NUC 10 (Frost Canyon) NUC, especially with the higher execution units for the 11the Gen NUC i3 (48 EU), i5 (80 EU) and i7 (96 EU).

I currently have a case open with the Intel NUC team and see if they can help investigate the underlying issue for their driver. For the time being, it looks like passthrough of the new iGPU is not fully functional when using ESXi 7.0 Update 2 and I will update this blog post if/when I have further updates to share.

VMware Cloud Foundation (VCF) on ASUS NUC 15 Pro (Cyber Canyon)

by // 3 Comments

With the release of ASUS’s 15th Generation NUCs powered by Intel’s new Core Ultra 2 processors (codenamed Arrow Lake), Intel has made yet another architectural change by dropping the long-standing Hyper-Threading feature from the Performance cores (P-cores), first introduced over two decades ago.


While the verdict is still out regarding this change, I was able to get hands on with an ASUS NUC 15 Pro (formally known as Cyber Canyon) to see what impacts it might have for running ESXi and even VMware Cloud Foundation (VCF), since that has been a frequent question from many since VCF 9.0 went GA last week.

ESXi on GMKtec NucBox K11

by // 7 Comments

The GMKtec NucBox has been growing in popularity amongst the VMware community as a modern AMD Ryzen-based alternative to the Intel/ASUS NUC, offering many of the same advantages while avoiding some of the drawbacks of Intel's Hybrid CPU architecture.

In preparation for my upcoming session at the inaugural VMUG Connect Conference in April, I have been experimenting with several modern hardware options, with the goal of deploying the full VMware Cloud Foundation (VCF) solution for use within a lab environment, while still staying budget friendly!

I know several folks have had great success with the GMKtec NucBox K8 Plus and it just so happens, while browsing the GMKtec website, I noticed an additional NucBox has just been released called the K11.


While the differences between the K8 Plus and K11 is pretty minimal, I was interested in validating some new hardware add-ons, so getting the latest hardware would hopefully give me the best chance!

In collaboration with the VMware {Code} team, I was able to get hands on with the latest GMKtec NucBox K11!

UPDATE (06/25/25) - The K11 can be used to run VCF 9.0, but you will NOT be able to run VCF Automation (VCFA). You can see how I have used the K11 is used in a "Hybrid" configuration in this blog post under Scenario 3.
