How to run Kali Linux on ESXi-Arm

by // 14 Comments

A few folks have been trying to get Kali Linux, a Debian-derived Linux distribution designed for digital forensics and penetration testing, to run on ESXi-Arm. Similiar to Raspberry Pi OS, the techniques outlined in this blog post can be used to convert the image-based system to a Virtual Machine that ESXi-Arm can then run natively. However, there is an issue when attempting to install grub during Step 16 where it can not locate an EFI partition.

With the help of Cyprien Laplace, we can now run Kali Linux on ESXi-Arm! You can find the detailed instructions below including installing VMware Tools for Kali Linux running on ESXi-Arm.

How to deploy Knative to a Tanzu Kubernetes Grid (TKG) Cluster on both vSphere with Tanzu and TKG Multi-Cloud?

by // Leave a Comment

This weekend I spent some time installing Knative, which is an open source framework that is built on top of Kubernetes. Knative is actually made up of two core components, serving and eventing. This quote from Ram Gopinathan, Principal Technology Architect, T-Mobile really sums up Knative quite nicely:

Knative helps our developers focus on building the business logic rather than worrying about building low-level platform capabilities such as build, deploy, autoscaling, monitoring, and observability.

There are a number of tutorials online for setting up Knative, most of which using Kubernetes in Docker (KinD) for easy local development. Since I have been spending quite a bit of time lately with both our vSphere with Tanzu and Tanzu Kubernetes Grid (TKG) Multi-Cloud solution, which both support deploying conformant and production grade Kubernetes (K8s) Clusters called a TKG Guest Cluster, I figure I might as well learn how to install Knative using these infrastructures.

The instructions below will be focus on deploying the Knative serving components. Once you have that setup, it is easy to deploy the eventing components which you can follow the official Knative documentation.

Quick Tip - Easily identify source DHCP server using ESXi DCUI

by // 1 Comment

While installing the ESXi 7.0 Update 1 on one of my physical system, I happened to be in the "Configure Management Network" section of the ESXi Direct Console UI (DCUI) and noticed something I had never seen before. As shown in the screenshot, it now shows the IP Address of the DHCP server in which ESXi received the DHCP lease.


I had not noticed this before and after asking on Twitter, it looks like this is definitely a new enhancement that was added fairly recently. I did not see this in one of my ESXi 6.7 Update 3 deployments, but it may have came in a later patch but definitely new in ESXi 7.0 or greater. Not only is this a quick and easy way to identify the DHCP server being used but in case you need to track down an unexpected rogue DHCP server running, this will certainly come in handy as pointed out by John.
