How to patch Intel NUC 10 with latest ESXi 7.0 update?

by 4 Comments

vSphere 7.0b was just released last week and one of the important fixes was to resolve an issue where Nested ESXi VMs were crashing upon powering on an inner-guest VM. This looks to have also affect newer generations of CPUs including Intel's 10th Gen Comet Lake which is also found in the latest 10th Gen Intel NUCs (Frost Canyon).

A number of folks quickly found that if you simply applied the ESXi 7.0b patch, an unexpected behavior occurred on the 10th Gen Intel NUCs and the onboard networking was lost upon a reboot. This occurs as the original ne1000 driver which had been replaced with a newer version found within ESXi 7.0b no longer recognizes the onboard Intel NIC. The solution is quite simple, create a new Image Profile that contains the Intel NUC NIC Driver.

Several of you have asked for instructions and although this is a pretty common vSphere workflow, I have documented the two supported options using the vSphere Image Builder utility but there are definitely other methods which will have the same results. If you have access to a vCenter Server 6.7 or newer, I recommend using the Image Builder UI. If vCenter Server access is not available, then you can use Image Builder with PowerCLI, however you will need to have access to a Windows machine as the Image Builder cmdlet is not supported with PowerCLI Core.

Note: To prevent this from happening in the future, I am also working with Songtao, the developer of the Intel NUC driver to see if we can rename the VIB which should prevent this from happening with future updates.

Passthrough of Integrated GPU (iGPU) for standard Intel NUC

by 1 Comment

Earlier this week I found out that it was possible to passthrough the Integrated GPU (iGPU) for standard Intel NUC which was motivated by a question I had saw on the VMware Subreddit. I have written about iGPU passthrough for Intel NUCs before but only for the higher end models which were the Hades Canyon NUC at the time.

To be honest, I never thought about trying this out with a standard NUC as I figured the iGPU may not be powerful enough or warrant any interests. After sharing the news on Twitter, I came to learn from the community that not only is this desirable for various use cases but some folks have also been doing this for some time now and have shared some the benefits it brings for certain types of workloads.

Below are the instructions I used to enable iGPU passthrough on an Intel NUC 10 (Frost Canyon) with vSphere 7.0. These instructions should also be applicable for other NUC models and earlier versions of vSphere including details around passthrough configuration persistency which I know some folks have ran into which I was able to figure out as part of this experiment.

Decoding Intel NUC “Canyon” Generation with CPU “Lake” Generation Codenames

by 9 Comments

Swift Canyon, Baby Canyon, Bean Canyon, Provo Canyon, Kaby Lake, Whiskey Lake, Coffee Lake ... these are just some of the Intel codenames that either refer to a NUC platform or CPU generation. I can understand the need for codenames, however for consumers, the various names are often confusing and being able to grok at which system is the "latest" is not always trivial. In some cases there are multiple updates to different generations of the platform all happening within a short period of time and most online sites may swap between codenames and the official "Nth" generation nomenclature.

I have been working with the Intel NUC platform from a VMware standpoint since the 6th Generation back in 2016 and even I still get confused at times on what is the latest "Canyon" NUCs and their respective "Lake" CPU generations. I can not imagine how complicated this might feel for some of our customers who are updating their VMware homelab every couple of years or someone who is just starting out for the first time. To not only help keep myself sane as I often get asked about Homelabs, literally on a weekly basis and to help educate others within out community, I have created a document which maps all Intel NUCs (full height) to their respective Nth generation along with the respective CPU architecture used in each platform.

Intel NUC 9 Pro & Extreme – First “Modular” NUC

by 21 Comments

The highly anticipated "modular" Next Unit of Computing (NUC) has just been announced at the Consumer Electronic Show (CES) this week, dubbed the Intel NUC 9 Pro (codename Quartz Canyon) and NUC 9 Extreme (codename Ghost Canyon). Boy am I super excited for this new platform and what it could mean for the VMware Community! 😍

Immediately off the bat, you can see that this is not your typical NUC "cube" form factor. Intel has completely redesigned the system from the inside and out, more on this in a bit. The key difference between the two NUC 9 variants (Pro and Extreme) are the CPU options, which are detailed below. For the remainder of this article, I will be focusing on the Pro version of the NUC 9 and I will call out any differences where applicable.

The use of the word "Pro" is also quite fitting as Intel is positioning this system as a high-end prosumer to Mid-Enterprise device compared to the traditional NUC. The NUC 9 Pro is targeting more demanding workloads such as Digital Content Creation, CAD/Manufacturing and Financial Service applications that either require a high-end graphics card or AI module for computing. When I first heard about this system from Intel, it conceptually reminded me of Apple's recent 2019 Mac Pro, which is also designed with modularity in mind and can cater to a variety of use cases.

Speaking of use cases, although Virtualization is not a target use case for this new platform, VMware customers have been taking advantage of the Intel NUCs for a number of years now and it is still by far the most popular platform for running a vSphere/vSAN/NSX Home Lab. However, one common complaint I often hear about the current generations of NUCs has been its CPU and I think the new NUC 9 Pro/Extreme will be a nice contender for current alternatives like the popular Supermicro E200-8D. Thanks to Intel, I was able to get my hands on a pre-production NUC 9 Pro unit for testing, so lets take a closer look at what this new platform has to offer!

ESXi on 10th Gen Intel NUC (Frost Canyon)

by 49 Comments

Just a heads up, if you are considering the latest 10th Generation of the Intel NUC (formally known as Frost Canyon) which are now available on Amazon, Newegg & SimplyNUC, there is an issue to be aware of. The onboard Intel NIC is not detected by ESXi which prevents the installer from proceeding. This issue was reported by a fellow reader named Ben who reached out to me over the holiday and with his help, I was able to get access to the system. It looks like the these NUCs have a newer version of I219-V NIC which is currently not recognized by either the vmklinux e1000 or ne1000 driver.

UPDATE (01/20/20) - As shared on Twitter last Friday, we now have an updated ne1000 driver that will detect the Intel NIC found in the new 10th Gen NUC. You will need to replace the existing ne1000 driver with the new offline bundle, which can be downloaded from here. I would like to remind folks that the Intel NUC is not an officially supported platform from VMware and although have have enable this new system for the community, it does not mean this system or previous generations are supported.

There are two options to author a new ESXi Image Profile containing the ne1000 driver, the easiest method is if you have an existing vCenter Server and using the vSphere H5 Client and Image Builder UI. Import latest ESXi 6.7 Update 3 Image Profile offline bundle along with the ne1000 offline bundle and then de-select the existing ne1000 driver as shown in the screenshot below.


Next, select the update ne1000 driver and then export the new Image Profile to an ISO which can then be used to install on the NUC.


For more details on how to use Image builder, please have a look at the official VMware documentation linked below.

Option 1: Use vSphere H5 Client and Image Builder UI in vCenter Server to create the new Image Profile with the ne1000 driver.

Option 2: Use PowerCLI and the Image Builder cmdlets to create the a new Image Profile with the ne1000 driver.

For those interested, here is the PCI ID mapping for the new NIC, which is also NOT on VMware's HCL.

0000:00:1f.6 Network controller Ethernet controller: Intel Corporation Ethernet Connection (10) I219-V
Class 0200: 8086:0d4f

Manually adding the PCI ID to the map files (which we had initially tried) will also not work as changes to the driver would be required to enable this device. At this time, if you wish to use this system with ESXi, it is recommended that you use the ESXi Native Driver for USB NIC Fling along with a supported USB NIC to get network connectivity and ESXi to install.

64GB memory on the Intel NUCs?

by 37 Comments

I just got my hands on a pair of 32GB SODIMM memory modules (64GB total) which I had been waiting to evaluate since last Fall. Apparently, it has taken some time for these high capacity memory modules to be readily available in the consumer market. Even after the announcement of the new 2018 Apple Mac Mini last year, which officially supports 32GB SODIMMS, I was not aware of any vendors who were selling these modules direct to consumers.


My primary interests in these memory modules was whether they would work on the latest Intel NUCs, specifically the Hades Canyon (NUC8i7HNK) which are the prosumer versions of the standard Intel NUCs that many folks use for vSphere Home Labs. Both the standard and Skull/Hades Canyon NUCs all officially support a maximum of 32GB of memory (2x16GB SODIMM), however it been hypothesized by the community that they *should* in theory be able to go up to 64GB, especially as some of the newer CPUs technically state support for it.
