Nutanix : Who deleted my VM ?

Someone deleted a VM from the AHV cluster. We can see a VM deletion task under Prism Element, but we can’t easiliy determine which VM got deleted and by whom? Can you help?

If you need more information on who deleted a specific VM, the only option that

Nutanix Flow isolation Policy with Terraform

Here we go with another blog post on Nutanix and Terraform. 
If you haven’t checked the first video on how to provision VMs on Nutanix AHV with Terraform, here is the link.

The idea of this post is to quickly show you how Terraform can be leveraged to create software-defined network security policies on AHV with Nutanix Flow. For more information on Nutanix Flow capabilities, please refer to the following link: Nutanix-Flow-datasheet

Nutanix and Terraform – VM’s Creation

I am sure you have heard of HashiCorp and Terraform solution.

Basically, Terraform is a tool/framework you can leverage to describe/define what your Infrastructure will look like and manage its provisioning (day 1) and Lifecycle (day2).

Nutanix and Gitlab – Foundation and Cluster Creation

Nutanix has a bunch of APIs that you can leverage to automate different processes and reduce operational time, effort, risks, and improve consistency. In the following example, we will see how GitLab can be used to deploy a new AHV cluster from scratch. 

Our Gitlab Project called “ntnx-automation” is composed of different files:

  • A README file, usually a documention, describing requirements, how to use the solution, etc.
  • A ntnx-scripts folder storing all scripts dedicated to the automation project.
