Suppose you or your company is building a new solution and you need a virtual IT lab to rapidly create and provision environments for build verification, test automation and/or manual testing. Plus, you can enjoy all the added features that come along with a cloud based virtual IT platform such as snapshotting current state and reverting back to previous state. What better way of experimenting than doing this on a nested environment? Performing the upgrade on a nested environment could save you the trouble and downtime of the production infrastructure, especially if you don’t have ‘spare’ ESX hosts to play with. What’s the catch? You’ve never done this before. Suppose you want to upgrade your entire production VSphere infrastructure. Why should I use this solution? What use cases is nested virtualization good for? Practice an Upgrade Procedure of your VSphere Infrastructure – Potentially it would be a little slower, but not much if you do it right, and I’ll explain more next.
– It’s great!! But not for all scenarios. – “It’s going to be extremely slow, isn’t it?!”īefore we move forward, let me answer your questions: – “Isn’t normal Virtualization good enough anymore?” – “Why would you ever want to do such a scary thing?”
I bet that when you first encountered nested virtualization, some of the first questions to pop into your head were most likely along of the lines of: In this article, I am going to answer some common questions, discuss performance and common use-cases, provide a short walkthrough on how to enable a Nested ESXi and provide a list of CloudShare’s preconfigured ESXi environments.
For that reason I decided to focus my article on the VMware hypervisor. The solution, commonly referred to as Nested ESXi, opens the door to a lot of interesting use cases such as development and testing, virtual training, or virtual sales demos and POCs.Īlthough the concept of nested virtualization is not limited to VMware, it is by far the most popular hypervisor.
This includes ESXi hypervisors, which can be installed as a virtual machines. One of the benefits of nested virtualization is running multiple hypervisors on the same host server. This post was originally published on Septemand updated November 14, 2019. By The CloudShare Team - / Sales Enablement
