ESX 3.x on VMware Cloud on AWS? 

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? 😉

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 “basic” 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 😊 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.

Native MAC Learning in vSphere 6.7 removes the need for Promiscuous mode for Nested ESXi

04.25.2018 by William Lam // 41 Comments

Over the years, several solutions have been developed here and here to help reduce the impact of promiscuous mode, which is a requirement for running Nested ESXi as a workload. Although these solutions worked extremely well, it however did require users to install additional software to enable this functionality. The most recent solution was a new Learnswitch VMkernel module (released as a VMware Fling) that enables MAC learning capabilities on ESXi.

Today, I am pleased to announce that with the release of vSphere 6.7, the MAC Learning functionality is now available as a native feature of the VMware Distributed Virtual Switch (VDS) and as some of you may have guessed from the title, promiscuous mode is also no longer a requirement for running Nested ESXi! I wanted to take a moment and thank Subin, Jobin, Sriram, Rajeev & Samuel from our Network and Security Business Unit (NSBU) at VMware who worked tirelessly to get this integrated and productized into ESXi. Not only will this benefit Nested ESXi workloads but also other solutions and use cases that have historically required the use of promiscuous mode. For customers who are still running ESXi 6.0 or 6.5, you should continue to use the Learnswitch Fling until you fully upgrade to vSphere 6.7.

To use the new MAC Learning functionality, you will of course need to upgrade to vSphere 6.7 (both vCenter and ESXi) but also upgrade to the latest VDS version which is 6.6. MAC Learning can be enabled on a per Distributed Virtual Portgroup bases and today, it is only available when using the vSphere API. For those that have used the VDS API to manage their VDS, you will simply use the existing ReconfigureDVPortgroup_Task() method and in 6.7, there now a new macManagementPolicy property which allows you to enable and define your MAC Learning settings. This new MAC Management Policy will also be the new preferred method for managing security policies going forward for a DV Portgroup and the previous security policy settings should no longer be used.

Disclaimer: Nested ESXi is still not officially supported by VMware. Please use at your own risk.  [Read more...]
