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.

Quick Tip - Workaround for unsupported processor error in Windows 11 for Arm on VMware Fusion

This morning I came across an intriguing post on the VMware Reddit channel where a user had ran into an issue while attempting to upgrade their Windows 11 on Arm VM, running VMware Fusion on an Apple Silicon system. The error message stated that the CPU processor is not currently supported for Windows as you can see from the screenshot below:

After sharing the thread internally, I immediately got an answer back from one of the VMware Fusion Engineers and this issue looks to have also recently impacted UTM and luckily, there was an easy solution using the following Windows registry hack:

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsSelfHost\Applicability : BranchName -> CanaryChannel
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsSelfHost\UI\Selection : UIBranch -> CanaryChannel

After applying the registry tweak, the VMware Fusion Engineer confirmed Windows Update was now able to successfully start as shared with their screenshot below.
