Running Nested ESXi, NSX-V or NSX-T on top of NSX-T

11.22.2019 by William Lam // 6 Comments

Nested Virtualization is an extremely useful tool that helps customers easily test and try out new VMware products and solutions before rolling that into a proper development environment for further validation. This is especially handy for those wanting to setup an NSX-based environment and simulating their actual deployment topology, configuration and upgrade workflows.

In this past year, I have seen a 10x increase in the number of NSX-T based questions that have come up from customers and our field, the adoption of NSX-T is definitely in full swing. As expected, questions about running Nested ESXi on top of a physical NSX-T deployment has come up and there has actually been several variations that have been asked about whether that is Nested ESXi using VSS, VDS, NSX-V or even NSX-T running on top of an N-VDS, which is the virtual switch that NSX-T uses.

Luckily all of these combinations work and just require some basic configuration changes within NSX-T. However, before I continue, let me remind folks again that VMware does NOT officially support Nested Virtualization.

ESX 3.x on VMware Cloud on AWS?ย 

10.10.2019 by William Lam // 2 Comments

VMworld Barcelona is just around the corner and this week I started working on building out the different demo environments which will all be running on VMware Cloud on AWS. In one of the demos, I need to have ESX 3.0 running, yes you read that correctly! ESX as in the original version with the Service Console (cos), some of you maybe too young to remember these good ol days? ๐Ÿ˜‰

First, Let me be clear, there really is no good reason for this except for the nostalgia purposes and for what I am trying to demonstrate in our VMworld session. If you are curious about the demo and attend VMworld, be sure to sign up for HBI1967BE Workload Migration Techniques for On-Premises and Cloud Infrastructures which I will be co-presenting with Emad Younis. Secondly, Nested Virtualization whether it is the latest version of ESXi or our very first release, is not officially supported.

Nested ESXi on VMware Cloud on AWS (VMC)

09.28.2018 by William Lam // 5 Comments

I have had a few folks ask about Nested ESXi support on VMware Cloud on AWS (VMC), so lets get that out of the way first. Nested ESXi is NOT supported by VMware on any of our platforms, whether that is an on-premises or a cloud environment like VMC or any 3rd party vendors that maybe using VMware software. For those wanting an "official" statement on Nested ESXi support, you can refer to KB 2009916.

UPDATE (02/10/20) - Updated my Automated vSphere Lab Deployment Script to support "basic" Nested vSphere environment running on VMC.

Was asked if it was possible to setup a โ€œbasicโ€ Nested vSphere environment for Automation/API testing running in #VMWonAWS

Just updated my Automated vSphere Deployment Lab Script https://t.co/50tJmcDcH2 to enable support for #VMC ๐Ÿ˜Š pic.twitter.com/n0SeNIaJm8

Now, we all know Nested ESXi works and it runs extremely well on vSphere. In fact, vSphere is the best platform for running any Hypervisor in a VM. This is also true for VMC, you can run a Nested ESXi VM in an SDDC, however there are some caveats compared to what you would experience in an on-prem environment. Below are some of the caveats to be aware of if you are considering running Nested ESXi on VMC.
