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.

Playing with Zero Touch Provisioning (ZTP) in vSphere 9.1 using an ASUS NUC

by // 2 Comments

Introduced in VMware vSphere Foundation (VVF) and VMware Cloud Foundation (VCF) 9.1, Zero Touch Provisioning (ZTP) is the next evolution of Auto Deploy. Like Auto Deploy, it automates both ESX installation and host configuration. Instead of relying on the traditional PXE/TFTP boot process and Host Profiles, ZTP uses modern UEFI HTTP Boot along with vSphere Configuration Profiles (VCP) to provision a fully configured ESX host that automatically registers itself into the desired vSphere Cluster.

While ESX has supported UEFI HTTP Boot for some time, adoption has been gradual as organizations continue to rely on existing PXE/TFTP-based deployment infrastructure. At the same time, the hardware ecosystem has steadily transitioned from legacy BIOS firmware to UEFI, making UEFI HTTP Boot more broadly available. Auto Deploy's iPXE implementation was a nice bridge to support traditional PXE/TFTP infrastructure while still getting the benefits of HTTP boot, especially when it comes to installing ESX over the network compared to a TFTP-based approach.

While cleaning out some old lab hardware, I came across a spare ASUS NUC 15 Pro that I was no longer using and wondered whether it supported UEFI HTTP Boot and could be repurposed for ZTP testing? 🤔

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

by // 10 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.
