Nested ESXi Virtual Appliances are now back under VMware Flings Community!

by // 25 Comments

I know many of our internal teams (field, engineering, support, etc.), customers and partners have heavily relied on my Nested ESXi Virtual Appliances (VA) over the years which makes it seamless to deploy both VMware Cloud Foundation (VCF) and VMware vSphere Foundation (VVF) lab environments for learning, testing, troubleshooting, automation and development purposes. To support our customers in troubleshooting and prototyping purposes, I also make use of my Nested ESXi VAs on a regular basis and have found this to be invaluable in aiding my day to day work.

As part of the VMware by Broadcom "Day 2" transition, the hosting platform that housed my Nested ESXi downloads was no longer available and that impacted both the standalone Nested ESXi downloads but also the Nested ESXi Content Library, which provided a convenient way to subscribe to all the VAs from your vCenter Server.

Today, I excited to share that my Nested ESXi Virtual Appliance downloads are back and they are now available under the VMware Flings program! 🥳

Refresher on Nested ESXi Networking Requirements

by // 11 Comments

Using Nested Virtualization and specifically Nested ESXi, which is running ESXi inside of a VM, has become so automatic and second nature for me and many in the VMware community, that I sometimes forget we still have brand new users who are experiencing ESXi for the very first time.

Nested ESXi is an extremely powerful capability for so many different use cases from development, testing and general learning purposes. Before jumping in and deploying your Nested ESXi environment, which I highly recommend using my Nested ESXi Virtual Appliances, you need to make sure that you have proper networking setup or you will run into all sorts of strange issues. For all VMware Nested Virtualization resources, tips and tricks, you will definitely want to bookmark this page HERE.

Disclaimer: Nested Nested ESXi is not officially supported by VMware and Nested Virtualization is only supported under limited scenarios. For more details, please refer to this VMware KB 2009916.

Nested ESXi installation using HTTPS boot over VirtualEFI in vSphere 8

by // 2 Comments

In vSphere 7.0 Update 2, an enhancement was made to the Virtual Machine's UEFI firmware called VirtualEFI that would enable ESXi to run in a VM (Nested ESXi) and perform an HTTP Boot given the ESXi bootloader URL without requiring any traditional PXE infrastructure.

This was especially useful for anyone testing or developing ESXi automation for use with ESXi Kickstart, where you can quickly prototype your automation without additional infrastructure dependencies and once the automation has been vetted, you can then leverage that exact same automation in your physical ESXi provisioning infrastructure.

The original solution had only supported HTTP and I recently came to learn that we can now also support HTTPS in vSphere 8!
