Configuring dnsmasq as PXE Server for ESXi 

by Leave a Comment

One really cool thing that I came to learn while setting up the infrastructure to network boot the latest Raspberry Pi 4 was the use of dnsmasq, which I have used in the past but I did not realize it could do so much more. In addition to providing DNS services, it can also be configured to run TFTP and provide DHCP capabilities which can then be used to support PXE installations.

Another neat feature of dnsmasq is ability to proxy to an existing DHCP server which is extremely useful for anyone with an existing DHCP infrastructure. Given the simplicity of dnsmasq and having already set this up for the rPI, I figure it would also be useful to take folks through in setting up dnsmasq to also support ESXi installations over PXE, since this still comes up from new folks just getting started with ESXi kickstart automation.

For more details about PXE installation of ESXi, I highly recommend this whitepaper and although it states 6.0, the concepts and configurations are still applicable to the latest ESXi 7.0 release.

Sonnet Solo5G Multi-Gig (1G/2.5G/5G) USB Adapter works with ESXi

by 2 Comments

Last week I caught this tweet from Blake Garner who is an active VMware Community member that I follow and I came to learn that Sonnet just launched their first Multi-Gigabit (1GbE, 2.5GbE & 5GbE) USB Network Adapter called the Solo5G.

This of course piqued my interest for VMware Homelabs as last year we had just enabled the first Multi-Gigabit USB Network Adapter from QNAP supporting ESXi using the popular USB Native Driver Fling for ESXi. The QNAP device uses an Aquantia chipset and I had a funny suspicion that the Sonnet device might be using either the exact same or simliar chipset.

To confirm my theory, I reached out to the folks over at Sonnet and they were kind enough to send me a unit for validation which just arrived earlier this week. I had an Intel NUC 10 (Frost Canyon) already running and I just plugged it in and to my surprise it worked immediately since it already had the USB Native Driver Fling installed.


So there you have it, same chipset as the QNAP and best of all this device is only $79.99 USD which be purchased directly from Sonnet here. As of writing this blog post, the Solo5G is much cheaper than the QNAP. In fact, it seems the price of the QNAP has significantly increased since I had first blogged about it. I think multi-gig NICs both USB-based but also PCIe and respective switches is starting to become more mainstream, at least in the consumer markets and this is certainly an easy way to add additional bandwidth without breaking the bank. Big thanks to the folks at Sonnet and Blake for sharing the news!

ESXi on the new 2019 Apple Mac Pro

by 11 Comments

Inquiries from customers on the support for ESXi on the latest 2019 Apple Mac Pro 7,1 has slowly been trickling in since the release of the system in late December. Officially, VMware currently does not support this platform and until we have a unit in-house to investigate further, this is the official stance.

With that said, several folks from the community have reached to me and shared some of their findings as it relates to ESXi with the new Mac Pro. A huge thanks goes out to Mike Rimmer who was able to go through the installation process and identified that the on-board NICs were not automatically detected by ESXI and the installation was unable to proceed. With the extensibility of the Mac Pro, Mike was able to add a supported Intel-based NIC to the system so that we could further understand the issue.

Upon closer investigation, it looks like the new Mac Pro uses two Aquantia based 10GbE NIC which is simliar to the 2018 Mac Mini which requires the Aquantia ESXi driver which was developed earlier last year.

AQC107 NBase-T/IEEE 802.3bz Ethernet Controller [AQtion]
Vendor ID: 0x1d6a
Device ID: 0x07b1

Although Mike did not have a chance to confirm this assumption, I did get validation from another customer who made the same observation when he attempted to install ESXi and once the Aquantia ESXi driver was incorporated into the latest ESXi 6.7 Update 3 image, both on-board NICs were automatically picked up by ESXi and installation was successful.

UPDATE (04/28/20) - ESXi 6.7 Patch 02 resolves a number of the issues mentioned below, please take a look at this blog post here for more details.

UPDATE 1 (01/16/19) - Thanks to our Graphics team who was kind enough to loan me their 2019 Mac Pro which literally came in yesterday! I had an idea which I wanted to run an experiment on which was to add a PCIe card w/M.2 NVMe SSD and see whether or not the Apple T2 Security Chip would have any affect on whether or not ESXi would be able to see the device. I was not super optimistic but I had a need for an additional M.2 device, so I went ahead and purchased a $15 PCIe adaptor. I was pleasantly surprise to see that ESXi not only detected the device but I was able to format a local VMFS volume and power up a functional VM! I guess this makes sense as only the Apple SSD's are cryptographically tied to the T2 chip and other PCIe devices would not be and this would allow customers to take advantage of this system right now for running non-MacOS guests (yes, T2 still affects the SMC).

I also ran another experiment by connecting a Thunderbolt 3 chassis which also had a supported M.2 NVMe to see if I was going to be lucky again. Although it looks like ESXi 6.7 Update 3 has resolved the PSOD'ing issue, ESXi was not able to see anything on the other end.

Note: Secure Boot must be disabled on the Mac Pro before you can install ESXi, you can find the instructions in this Apple KB.


This was certainly some good news but like the 2018 Mac Mini, the new 2019 Mac Pro also ships with the Apple T2 Security Chip which has proved challenging for ESXi as mentioned here along with some known caveats. For now, I would hold off making any purchases of the new Mac Pro if you intend to run ESXi. VMware does officially support ESXi on the last current generation of Mac Pro 6,1 along with Mac Mini 6,2 and Mac Mini 7,1 which are all on the official VMware HCL.

I will continue to update this article as new information and findings are shared with me.

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!

VMworld Startup: Hivecell – Stackable Edge Computing

by Leave a Comment

One thing I really enjoy at VMworld when I have a few minutes to spare between sessions and customer meetings is to walk around the Solutions Exchange and learn about what our partners are doing in the VMware eco-system. I usually do not make it in very far before bumping into an old colleague or customer before having to run to my next engagement, but some times I get lucky.

While walking the show floor, I came across a really interesting company that immediately caught eye and you can probably guess why from the picture I took below.


The company is called Hivecell and they make it super easy for Global 500 companies to deploy and maintain software at the Edge without requiring a large IT team to manage the deployments which can be spread across hundreds if not thousands of sites with very little to no IT staff.

One of the biggest challenges with Edge Computing is being able to process the large quantity of data being generated in all of these remote locations on a daily basis. In some cases, the dataset can grow up to several Terabytes and it is no longer feasible to send all of this data to the Cloud or back to your Datacenter to extract the business intelligence and value. In fact, depending on the connectivity of your remote site, it can take weeks before the data is available. For any type of real or near-real time applications, the window where the data is of value can literally be hours if not minutes and it must be processed immediately at the Edge.

Speaking of use cases, here are some of the scenarios where Hivecell believes they can really help with their solution, more details about each use case can be found here.

  • Petrochemicals
  • Renewable Energy
  • Quick Service Restaurant Chains
  • Manufacturing
  • Healthcare
  • Weather
  • Data Science
  • Hotels

Apple Mac Mini on VMware HCL!

by 9 Comments

For the past 6 years, the Apple Mac Mini has been one of the most popular hardware platforms for Virtualizing MacOS running on VMware vSphere enabling our customers to develop and build iOS and MacOS applications. With that said, VMware has historically only supported two Apple hardware platforms: Xserve (now EOL'd) and the Mac Pro (6,1) which is officially listed on VMware's Hardware Compatibility list and this has been officially supported by VMware since 2012 when we first introduced support for MacOS Virtualization with the vSphere 5.0 release.

As many of you know, I have been a huge advocate of this platform for a number of years now and I have been working with various Engineers over the years to ensure that we have the exact same user experience when working with ESXi on the Mac Mini as you do with the Mac Pro. I still recall in the early days where it took several "hacks" to get ESXi to successfully boot and install.

Today, ESXi installs on the Mac Mini just like any other x86 platform. It runs amazing well for our customers, especially for a consumer device, who have deployed them in their datacenters ranging from a couple hundred to several thousands for some of our larger Enterprise customers, one such example is MacStadium, the largest Apple Infrastructure-as-a-service provider which many of the Fortune 100/500 companies are leveraging to provide them with a platform to build and develop for the Apple eco-system.
