ESXi on 12th Gen Intel NUC Pro (Wall Street Canyon)

Intel's Alder Lake-based 12th Gen "Wall Street Canyon" NUC Professional series is currently been shipped out. This article takes a deep look at their capabilities to run VMware ESXi. While VMware does not officially support NUCs, they are ubiquitous in many home labs and test environments. They are small, silent, transportable, and have very low power consumption, making them a great server for running your inexpensive home lab. The Wall Street Canyon is available with i3, i5, and i7 CPUs. The i5 and i7 versions are also available with vPro Support.

  • NUC12WSHv7 / NUC12WSKv7 (Intel Core i7-1270P vPro - 4 x up to 4.80 GHz / 8 x up to 3.50 GHz)
  • NUC12WSHv5 / NUC12WSKv5 (Intel Core i5-1250P vPro - 4 x up to 4.40 GHz / 8 x up to 3.30 GHz)

HCL and VMware ESXi Support

Intel NUCs are not supported by VMware and are not listed in the HCL. Not supported means that you can't open Service Requests with VMware when you have a problem. It does not state that it won't work.

ESXi 8.0 - ESXi runs out of the box with the original image.

ESXi 7.0 - The Community Networking Driver for ESXi is required.

Currently, there is no driver available for ESXi 6.x

To clarify, the system is not supported by VMware, so do not use this system in a productive environment. I can not guarantee that it will work stable. As a home lab or a small home server, it should be fine.

Network (Intel I225-LM) - "No Network Adapters" Error with ESXi 7.0
The Community Networking Driver for ESXi is required to install ESXi 7.0 on the 12th Gen NUC. See Installation for instructions.

Storage (AHCI and NVMe)
The storage controller works out of the box with ESXi 7.0 and ESXi 8.0.

Tested ESXi Versions

  • VMware ESXi 8.0
  • VMware ESXi 7.0 U3 (Custom Image only)
  • VMware ESXi 7.0 U2 (Custom Image only)


When you try to install ESXi 7.0 or 8.0 on a system with a 12th Gen Intel CPU, the installation fails with a purple diagnostics screen:

HW feature incompatibility detected; cannot start

Fatal CPU mismatch on feature "Hyperthreads per core"
Fatal CPU mismatch on feature "Cores per package"
Fatal CPU mismatch on feature "Cores per die"

This problem is caused by the new CPU architecture which includes different types of cores - Performance-cores and Efficient-cores. With vSphere 7.0 Update 2, the kernel parameter cpuUniformityHardCheckPanic has been implemented to address the issue. The option can be configured with the following command:

# localcli system settings kernel set -s cpuUniformityHardCheckPanic -v FALSE 

An easy workaround is to temporarily disable E-cores, install ESXi, set the parameter, and re-enable E-cores. If you want to keep E-cores enabled during installation, see this article with a scripted install example.

If you want to use ESXi 8.0, just download the Image and create a bootable USB flash drive.

If you try to install ESXi 7.0, the installer fails with a "No Network Adapters" error. A driver for the Intel I225-LM 2.5GbE adapter is not bundled in the standard ESXi Image but is available as a community-based VMware Fling.

How to create a Custom ESXi Image
This option explains how to create the Custom Image with PowerCLI. The Image can be used to install ESXi from scratch.

  1. Download the driver
  2. Copy the driver to your Build Directory (c:\esx) for example
  3. Open PowerShell
  4. Run the following commands in your build directory:
    # (Optional) Install PowerCLI Module 
    Install-Module -Name VMware.PowerCLI -Scope CurrentUser
    Export-ESXImageProfile -ImageProfile "ESXi-7.0.0-15843807-standard" -ExportToBundle -filepath
    Add-EsxSoftwareDepot .\
    Add-EsxSoftwareDepot .\
    New-EsxImageProfile -CloneProfile "ESXi-7.0.0-15843807-standard" -name "ESXi-7.0.0-15843807-NUC" -Vendor ""
    Add-EsxSoftwarePackage -ImageProfile "ESXi-7.0.0-15843807-NUC" -SoftwarePackage "net-community"
    Export-ESXImageProfile -ImageProfile "ESXi-7.0.0-15843807-NUC" -ExportToIso -filepath ESXi-7.0.0-15843807-NUC.iso
  5. Use the ISO image to install ESXi. The simplest way to install ESXi is by using the ISO and Rufus to create a bootable ESXi Installer USB Flash Drive. No custom BIOS Settings are required.

If you have already installed ESX (with a USB NIC for example) you can install the newer driver with the following command:

# esxcli network firewall ruleset set -e true -r httpClient
# cd /tmp/
# wget
# esxcli software vib install -d


The performance of a single NUC is sufficient to run a small home lab including a vCenter Server and 3 virtual ESXi hosts. It's a great system to take along for demonstration purposes. If you have multiple systems and a vCenter Server you can build a powerful cluster.

The following chart is a comparison based on the NUCs PassMark score. The performance gap to previous generations is huge, which is a result of going up from 4 to 16 Cores.

Power consumption

NUCs have a very low power consumption. I've measured the power consumption of a NUC12WSHv5 in 3 states: Idle (ESXi in Maintenance Mode), Average Load (1 vCenter, 4 Linux VMs), and during a Stress test. The NUC has been configured with 64GB RAM and no HDD or SSD. The power policy was configured to be "Balanced".

  • Idle: 16 W
  • Average Load: 24 W
  • Stress Test: 65 W

The average operating costs are a little over 5 Euros per month:
17 watt * 24 h * 30 (days) = 17,28 KWh * 0,30 (EUR) = 5,18EUR
Consumption measured with Homematic HM-ES-PMSw1

  1. Curious, in the performance chart the Core i5-1240P comes in slightly on top of the supposedly more powerful i7-1260P. Is it a simple mistake, or what can explain this?
    Thanks for the great write-up, as always very helpful, both for decisions and actual use!

  2. What is the practical difference betveen vPro and regulat CPU in ESXi? Is it only the performance, or is there something like "better sandboxing" or some other features that ESXi can utilise on vPro CPUs?

    1. I too, have wondered that, as I got the pro edition i5-1240P as we have not been seeing the i5-1250P variants.

      I had hoped that some of the remote access features would be easy to enable so that you could use it similarly to IPMI, etc. However, it doesn’t seem to be that easy to actually set up remote access and I don’t think we have true vPro on the i5-1240P NUCs.

      1. The NUC12WSHv50L has full AMT/vPro on it. I have one on my desk currently with the full remote desktop feature running.

  3. Hallo zusammen,
    hatte es auch schon wie beschrieben hinbekommen, es auf einem Fujitsu Esprimo g9012 mit einer Intel i7 12700T CPU zu installieren und es werden nur 12 der 20 Kerne angezeigt.
    Etwas enttäuscht war ich schon, aber auch verständlich, die sind interessiert, teure Server zu verkaufen, weitaus interessanter war es als ich Proxmox in der Aktuellen 7.3 Version installiert habe, dort werden auch alle 20 Kerne genutzt. Ein Grund mehr auf Proxmox umzustellen!

    1. Der i7-12700T hat nur 12 Cores. Lediglich Hyperthreading kann nicht genutzt werden, was aber nur in wenigen Situationen einen Vorteil bringt.
      Wahrscheinlich werden die asymmetrischen CPU durch VMware auch irgendwann unterstützt. Der Fokus liegt hier aber ganz klar auf Enterprise Hardware.

  4. Thank you for this exellent article.

    One Question is open for me:
    - do i need the vPro Version?

    As i see from other articles, the Intel Virtual TPM (vTPM) is not supported by VMWare.
    Only the vPro Versions of 12th Gen Intel NUC Pro have a real TPM 2.0 chip.

    For a Windows 11 Guest we need a virtual TPM Module.

    If i want to create a Windows 11 Guest in an Home Lab ESXi 8 on Intel NUC, do i need the vPro Version?
    Does the TPM Chip in the vPro NUC work with ESXi 8?

      1. AMT is there. Full remote desktop w/ remote media even is possible to configure on the unit. There is no CTRL+P setup though, all the setup/provisioning is done through uEFI interface.

  5. combining boot options cpuUniformityHardCheckPanic=FALSE and systemMediaSize seems to be buggy when installing 8.0b on my NUC12WS
    when only using cpuUniformityHardCheckPanic=FALSE no issues.

  6. I have NUC NUC12WSHI5 Core i5-1240P 2000GB 64GB, I've tried to install ESXI 8 but
    can't install the system because ESXI doesn't see any hard drive (Hard drive SSD (M.2) 2GB) How can I fix it?

    1. ESXi only recognize some NVME controller, use a Samsung one and it will work flawless. For the others it's a hit or miss. I tried a Silicon Motion and it have the same problem as yours.

  7. I see no way to disable the E-Cores in BIOS...Am I missing something? trying to get around the purple-screen of death

  8. Good morning. I've installed ESXI8 on my NUC 12 Pro (NUC12WSHi7).
    I've installed 2 virtual machine on it : One windows 11 and one ubuntu.

    All works fine except the sound. I don't have any sound.
    It seems that there is no sound driver for the NUC12 Pro for ESXI8.

    It's very frustrating.
    The VM seems okay but no sound is heard on the real machine. (on client side)

    Where can i find a sound driver for NUC12 Pro (NUC12WSHi7) for ESXI8 ?
    Can someone help me ?
