VMware ESXi 7.0 Update 3 on Intel NUC

VMware vSphere ESXi 7.0 Update 3 has been released in October and before you start to deploy it to production, you want to evaluate it in your testing environment or homelab. If you have Intel NUCs or similar hardware you should be very careful when updating to new ESXi releases as there might be issues. Please always keep in mind that this is not an officially supported platform and there might be compatibility issues.

In vSphere 7.0, there are ups and downs with consumer-grade network adapters. Since the deprecation of VMKlinux drivers, there is no option to use Realtek-based NICs, and previous versions had problems with the ne1000 driver. Luckily there is the great Community Networking Driver for ESXi Fling that adds support for a bunch of network cards and VMKUSB-NIC-FLING always covers your back.

I've updated my NUC portfolio to check which NUCs are safe to update and what considerations you have to take before installing the update. Additionally, I'm taking a look at the consequences of the recently deprecated USB/SD-Card usage for ESXi Installations and some general Issues in 7.0u3.

ESXi 7.0 Update 3 with Community Network Driver (8th Gen Bean Canyon / 11th Gen NUC)

The ne1000 driver packed in 7.0 Update 3 still does not work with the Intel I219-V (6) network adapter, which is used in the 8th Gen Bean Canyon NUCs. But this problem can be easily solved with the Fling Driver. For reference, these are the ne1000 drivers versions used in 7.0 releases:

ne1000 0.8.4-10vmw.700.1.0.15843807 <- ESXi 7.0 GA
ne1000 0.8.4-11vmw.701.0.0.16850804 <- ESXi 7.0 Update 1
ne1000 0.8.4-11vmw.702.0.0.17630552 <- ESXi 7.0 Update 2
ne1000 0.8.4-11vmw.703.0.0.18644231 <- ESXi 7.0 Update 3

For the following NUCs, the Fling driver is required:

  • NUC8i7BEH/NUC8i7BEK (Intel Core i7-8559U - 4 Core, up to 4.5 GHz)
  • NUC8i5BEH/NUC8i5BEK (Intel Core i5-8259U - 4 Core, up to 3.8 GHz)
  • NUC8i3BEH/NUC8i3BEK (Intel Core i3-8109U - 2 Core, up to 3.6 GHz)
  • 11th Gen NUC (NUC11PAQi7, NUC11PAHi7, NUC11PAKi7, NUC11PAQi5, NUC11PAHi5, NUC11PAKi5, NUC11PAHi3, NUC11PAKi3, NUC11TNHv70L, NUC11TNHv7, NUC11TNHv50L, NUC11TNHv5, NUC11TNKv7, NUC11TNKv5, NUC11TNHi70Q, NUC11TNHi70L, NUC11TNHi7, NUC11TNHi50W, NUC11TNHi50L, NUC11TNHi5, NUC11TNHi30P, NUC11TNHi30L, NUC11TNHi3, NUC11TNKi7, NUC11TNKi5, NUC11TNKi3)
  • Any NUC-Style alternative with 11th Gen Intel CPU and 2.5GBps Network Adapter (Eg. ASRock Industrial NUC 1100)

Download the Update Bundle and Fling:

New Installation
If you want to do a fresh install of ESXi 7.0 U3, you have to create a custom image, including the Community Driver.

Use the following PowerShell commands to add the community driver to the stock image.

Add-EsxSoftwareDepot .\VMware-ESXi-7.0U3-18644231-depot.zip
Add-EsxSoftwareDepot .\Net-Community-Driver_1.2.2.0-1vmw.700.1.0.15843807_18835109.zip
New-EsxImageProfile -CloneProfile "ESXi-7.0U3-18644231-standard" -name "ESXi-7.0U3-18644231-NUC" -Vendor "virten.net"
Add-EsxSoftwarePackage -ImageProfile "ESXi-7.0U3-18644231-NUC" -SoftwarePackage "net-community"
Export-ESXImageProfile -ImageProfile "ESXi-7.0U3-18644231-NUC" -ExportToISO -filepath ESXi-7.0U3-18644231-NUC.iso

Use the ESXi-7.0U3-18644231-NUC.iso image to install ESXi 7.0 U3 on your NUC. (Create a Bootable ESXi Installer USB Flash Drive

If you've already installed ESXi, use the following commands to create an update bundle that contains the required package.

Add-EsxSoftwareDepot .\VMware-ESXi-7.0U3-18644231-depot.zip
Add-EsxSoftwareDepot .\Net-Community-Driver_1.2.2.0-1vmw.700.1.0.15843807_18835109.zip
New-EsxImageProfile -CloneProfile "ESXi-7.0U3-18644231-standard" -name "ESXi-7.0U3-18644231-NUC" -Vendor "virten.net"
Add-EsxSoftwarePackage -ImageProfile "ESXi-7.0U3-18644231-NUC" -SoftwarePackage "net-community"
Export-ESXImageProfile -ImageProfile "ESXi-7.0U3-18644231-NUC" -ExportToBundle -filepath ESXi-7.0U3-18644231-NUC.zip

Use ESXi-7.0U3-18644231-NUC.zip to update ESXi 7.0 U3:

# esxcli software vib install -d /path/ESXi-7.0U3-18644231-NUC.zip


ESXi 7.0 Update 3 on any other Intel NUC

Any other NUC, down to the 5th Gen can be installed and upgraded with the original image.

ESXi 7.0 Update 3 with VMKUSB-NIC-FLING

If you want to use USB-based network adapters, you can use the VMKUSB-NIC-FLING.

Download the Update Bundle and Fling:

Create ISO and Update Bundle

Add-EsxSoftwareDepot .\VMware-ESXi-7.0U3-18644231-depot.zip
Add-EsxSoftwareDepot .\ESXi703-VMKUSB-NIC-FLING-51233328-component-18902399.zip
New-EsxImageProfile -CloneProfile "ESXi-7.0U3-18644231-standard" -name "ESXi-7.0U3-USBNIC" -Vendor "virten.net"
Add-EsxSoftwarePackage -ImageProfile "ESXi-7.0U3-USBNIC" -SoftwarePackage "vmkusb-nic-fling"
Export-ESXImageProfile -ImageProfile "ESXi-7.0U3-USBNIC" -ExportToIso -filepath ESXi-7.0U3-USBNIC.iso
Export-ESXImageProfile -ImageProfile "ESXi-7.0U3-USBNIC" -ExportToBundle -filepath ESXi-7.0U3-USBNIC.zip

You should now have two files, an .ISO for new installation and a .ZIP for updates.

Alternative Update Option for Installations with VMKUSB-NIC-FLING

If you try to update existing installations directly using original bundles, the update fails with the following error message.

[root@esx4:~] esxcli software vib install -d /vmfs/volumes/images/VMware/Fling/ESXi703-VMKUSB-NIC-FLING-51233328-component-18902399.zip
 VIB VMW_bootbank_vmkusb-nic-fling_1.8-3vmw.703.0.15.51233328 requires vmkapi_2_9_0_0, but the requirement cannot be satisfied within the ImageProfile.
 VIB VMW_bootbank_vmkusb-nic-fling_1.8-3vmw.703.0.15.51233328 requires vmkapi_incompat_2_9_0_0, but the requirement cannot be satisfied within the ImageProfile.
 Please refer to the log file for more details.
[root@esx4:~] esxcli software vib install -d /vmfs/volumes/images/VMware/vSphere\ 7.0/VMware-ESXi-7.0U3a-18825058-depot.zip

 Please refer to the log file for more details.

The solution is quite simple. You first have to remove the Fling from the Rebooting Image and then install the Update and new driver.

  1. Place the Host into Maintenance Mode
  2. Remove the Fling. Depending on how you've installed it, one of the following commands will remove it:
    # esxcli software vib remove -n vmkusb-nic-fling
    # esxcli software component remove -n VMware-vmkusb-nic-fling
  3. Install the ESXi Update (Remember to always use the full path when installing bundles with esxcli. A relative path does not work!)
    # esxcli software vib install -d /[PATH]/VMware-ESXi-7.0U3a-18825058-depot.zip
    # esxcli software component apply -d /[PATH]/ESXi703-VMKUSB-NIC-FLING-51233328-component-18902399.zip
  5. Reboot ESXi

ESXi 7.0 Update 3 and the deprecation of SD card/USB as a boot device

For production environments, you have to consider moving away from SD cards and USB drives as boot devices for ESXi. They still work in ESXi 7.0 but VMware has announced that they will no longer be supported in future versions.

As of today, and for Home Labs, especially with U3 - It is perfectly fine to go on with USB drives.

  1. Thanks for the article but I need more details on how to use those provided PowerShell commands to add the community driver to the stock image. Any additional help is greatly appreciated.

    1. Now that VMWare has removed ESXI 7.0 v3, VMware-ESXi-7.0U3-18644231-depot.zip is no longer available. Can you update this with the remaining version 2a? Thanks

      1. This post is solely on ESXi 7.0u3 support (Wich will be back eventually). You can just use the same commands with older bundles.
