Self-Contained & Automated VMware Cloud Foundation (VCF) deployment using new VLC Holodeck Toolkit

03.29.2023 by William Lam // 11 Comments

I recently came to learn about a really neat solution that was released called the VMware Cloud Foundation Lab Constructor (VLC) Holodeck Toolkit, which makes it super easy for anyone to deploy a complete functional VCF environment, fully self-contained and deploys all the required networking and infrastructure services that dramatically reduces the amount of time and effort to deploy a VCF environment for evaluation or learning purposes.

What is unique about the VLC Holodeck Toolkit is that it ships with a special vPodRouter VM, which provides all the networking and connectivity that is required to deploy a typical production VCF environment. If this sounds familiar, this is exactly how VMware Hands-On-Labs (HOL) works where isolated networking is provided to each "vPod" through their vPodRouter VM. In addition, the VLC Holodeck Toolkit also builds a custom Windows Jumphost (bastion) ISO that includes all the infrastructure services like DNS, Directory, Certificate Authority, etc. that is fully configured and ready to use once it is deployed and this is how users interact with the VCF environment.

With the VLC Holodeck Toolkit providing and building all the necessary "virtual" infrastructure, the barrier to entry is further reduced and customers can easily stand up a fully functional VCF environment running on just a single ESXi host without any special physical networking requirements. For a detailed overview of the solution, check out overview video below.


After learning about the solution, I also had the opportunity to kick the tires and provide some early feedback, which included a few additional optimizations that made its way back into the toolkit. For those interested, below is the high level workflow to go from a single ESXi host with minimal configuration to a fully functional VCF environment.

Nested ESXi installation using HTTPS boot over VirtualEFI in vSphere 8

01.13.2023 by William Lam // 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!

Using vSphere Lifecycle Manager (vLCM) to remediate Nested ESXi host with CPU on the host is not supported 

10.24.2022 by William Lam // 4 Comments

If you are running a Nested ESXi VM on top of a physical ESXi host that does not have a supported CPU and you are using vSphere Lifecycle Manager (vLCM), the pre-check and/or remediation will fail due to the following error:

The CPU on the host is not supported by this image


The solution is actually quite simple and is similiar to what you had to do for your physical ESXi host by adding the ESXi kernel boot option allowLegacyCPU=true to successfully boot and install ESXi as recently explained in this blog post. To emulate this setup, I am using my trusty 2011 Apple Mac Mini which is running ESXi 8.0 with the kernel boot option and it is then running a Nested ESXi 7.0 Update 3g VM.
