ESXi-Arm V2 Easter Egg

by // 5 Comments

A new version of the ESXi-Arm Fling (V2) was recently released and the major update to the ESXi-Arm V2 Fling is that it is now based on the latest ESXi 8.x codebase, which is currently 8.0 Update 3b. In my blog post, I had hinted there was a small easter egg 🐣 the Engineering team had included in the ESXi-Arm Fling update, which I did not know about until they had mentioned it!

Since no one has officially found the easter egg, I figured it might be time to break the silence and share as I think it can actually benefit some users based on their usage of ESXi, especially from a testing and/or learning perspective such as playing with the vSphere API as just one example.

Quick Tip - Disable network traffic monitoring (promiscuous) UI prompt in VMware Fusion

by // Leave a Comment

While working on some demos planned for my VMware Explore session, Tech Deep Dive: Automating VMware ESXi Installation At Scale [CODEB1574LV], I kept getting this network monitoring prompt when powering up my Nested ESXi VM running in VMware Fusion.


Since Nested ESXi requires the use of promiscuous mode (for inner-VM networking), you will be prompted to approve of the request or networking will be disabled. For demo purposes, you probably do not want this prompting and I was wondering if this could be disabled. After a quick ping in our internal VMware Hosted Google Space, I learned that we can disable the UI prompt by adding a VMX option to the VM.

Incorrect guestOS type for Nested ESXi causes vCLS issues with VMware Cloud Foundation (VCF) Holodeck Toolkit

by // Leave a Comment

Several months back, I started noticing an increase number of folks reporting problems powering on their vSphere Cluster Services (vCLS) VM when using the VMware Cloud Foundation (VCF) Holodeck Toolkit solution and the following workaround can be applied, which came directly from the Holodeck developers.

While a workaround exists including vCLS script located at C:\VLC\VLC-Holo-Site-1\vclsfix, it was very puzzling because this seems to only happen with the Nested ESXi VMs and the VCF Holodeck Toolkit and it was NOT observed when deploying a regular Nested ESXi environment, but I never took a closer look to see why that might be.

A few weeks back, I recieved an email from Mike Foley (former vSphere HA and vCLS PM), I came to learn the reason folks using the VCF Holodeck Toolkit was seeing this problem and it was specific to that solution due to how the guestOS was configured for the Nested ESXi VMs.
