ESXi on Arm Fling

I think it was to the end of VMworld 2018 when I first read about ESXi on Arm.

Blogposts on ESXi on Arm

Unfortunately, at this time, it was only available VMware internally.

For VMworld 2019, the topic of ESXi on Arm appeared again. This time, as a VMware employee, I wanted to know and understand more. But the image was not available to everyone.

Now, with VMworld 2020 in the books, ESXi on Arm is available as Fling!

Now finally, time to dust off my Raspberry Pi 4b.

My Raspberry Pi 4b

  • 4 GB memory
  • Samsung FIT Plus 32GB Typ-A 400 MB/s USB 3.1 Flash Drive (OS)
  • Samsung FIT Plus 256GB Typ-A 400 MB/s USB 3.1 Flash Drive (Datastore)
  • SanDisk Extreme microSDHC 32GB

Get started

First, download the ISO file for ESXi on Arm Fling. You need a My VMware (https://my.vmware.com) account. If don’t have one yet, you can register for free. It takes only a few minutes to do so.

Next, download both pdf files – ESXi-Arm-Fling-Doc and Fling-on-Raspberry-Pi. The ESXi-Arm team has created easy to follow, step-by-step instructions.


My VMware colleague Nico Vilbert wrote a tutorial, adding photos for some of the step-by-step instructions.


After the installation, I realized that the host did not show any storage, even though a 256 GB USB stick was attached. When searching for help (manually attach USB device as VMFS datastore in ESXi), I found an instruction on Virten.net.

Followed each step of the instructions, and it works.

Next challenge. The scratch partition had to be added manually. I found the How-to within the VMware documentation for vSphere 7.

If you want to hear more about ESXi on Arm Fling – you can listen to episode 173 of Virtually Speaking podcast.


The team behind the fling is very interested in feedback on ESXi-Arm.
Here are few ways to engage with them

They want feedback to understand how the fling can be used. The feedback will help to prioritize future plans.

So please give the ESXi-Arm Fling a try today and let us know what you think!

Additional Information

I did not stick to my own words. When writing a post, I wanted to make sure everyone can follow and understand the post.

So, here are some additional information which should help to understand.

ESXi on Arm
ESXi or more specific VMware ESXi is the first part.

VMware ESXi (formerly ESX) is an enterprise-class, type-1 hypervisor developed by VMware for deploying and serving virtual computers. As a type-1 hypervisor, ESXi is not a software application that is installed on an operating system (OS); instead, it includes and integrates vital OS components, such as a kernel.

The name ESX originated as an abbreviation of Elastic Sky X. In September 2004, the replacement for ESX was internally called VMvisor, but later changed to ESXi (as the “i” in ESXi stood for “integrated”).

The second part is Arm.

ARM (previously an acronym for Advanced RISC Machine and originally Acorn RISC Machine) is a family of reduced instruction set computing (RISC) architectures for computer processors, configured for various environments. Arm Holdings develops the architecture and licenses it to other companies, who design their own products that implement one of those architectures—including systems-on-chips (SoC) and systems-on-modules (SoM) that incorporate memory, interfaces, radios, etc. It also designs cores that implement this instruction set and licenses these designs to a number of companies that incorporate those core designs into their own products.

In short, ESXi on Arm is VMware’s hypervisor running on Arm Architecture.

I hope the added information gives the full picture of ESXi on Arm.
