VMware Homeserver – ESXi on 6th Gen Skull Canyon Intel NUC

Intel has launched the Skull Canyon NUC which completes the 6th Gen NUC family with a powerful Core i7 CPU and a redesigned chassis. I will take a look at its capabilities as homeserver running VMware ESXi. NUCs are not officially supported by VMware but they are very widespread in many homlabs or test environments. They are small, silent, transportable and have a very low power consumption, making it a great server for your homelab. 6th Gen NUCs in the old layout are also available with an i3 or i5 CPU which have been reviewed here.

Additional USB NIC for Intel NUCs running ESXi

Intel NUCs with ESXi are a proven standard for virtualization home labs. I’m currently running a homelab consisting of 3 Intel NUCs with a FreeNAS based All-Flash Storage. If you are generally interested in running ESXi on Intel NUCs, read this post first. One major drawback is that they only have a single Gigabit network adapter. This might be sufficient for a standalone ESXi with a few VMs, but when you wand to use shared Storage or VMware NSX, you totally want to have additional NICs.


A few month ago, this problem has been solved by an unofficial driver that has been made available by VMware engineer William Lam.

ESXi Installation on NUC6i7KYK fails with “Fatal error: 10 (Out of resources)”

When you try to install VMware ESXi 6.0 on the latest Skull Canyon Intel NUC (NUC6i7KYK), the installation fails with one of the following error messages:

Error loading /tools.t00

Decompressed MD5: 000000000000000000000000000000

Decompressed MD5: 000000000000000000000000000000
Fatal error: 15 (Not found)

This problem is caused by the Thunderbolt Controller, which is a new component in the NUC6i7KYK, and therefore only the Skull Canyon NUC is affected. The problem can be solved by temporarily disabling the Thunderbolt controller during installation.

Announced in my VMware HCL in JSON Format post a few days ago, here is now a working version of my script. The script does not create a fancy report at the moment, it just writes some output and the result. It’s only intended to show that it actually works. Here is an example:

The SSLv3 issue has been addressed in this releases. Support for SSLv3 protocol is enabled by default but is configurable. This removes the risk of an unmanageable ESXi hosts when you update ESXi to the latest version, without having the latest vCenter Server.

VMware HCL in JSON Format

When you want to upgrade ESXi hosts, or just want do create health reports, you might want to verify that the system is listed in VMwares HCL. The HCL is currently only provided as website which might be a problem for automated reports. To make HCL checks, I’ve transformed the HCL into the JSON format, which works great in scripts. Here is the result:
