CUSTOMIZING AHV VMS

This article provides an introduction to the nature of Guest Customization support for AHV VMs and how one can configure this using the Prism Central v3 APIs.

Overview

Using the AHV Image Services and Clone functionality, users can reduce the amount of time needed to bring up an AHV Virtual Machine (VM). As per their organisational security standards, users can have base images with the necessary software and patches installed in the Guest OS. However, in certain deployments, there is a need to make changes specific to a particular instance. This can be achieved via the Guest Customization functionality which allows users to have OS customization while creating a VM from AHV Image or Cloning an existing VM. The mechanism to customize a guest depends on the Guest OS; Cloud Init is used for customizing Linux Guests and SysPrep is used for Windows Guests.

In order to customize guests via v3 API, one has to make a POST request to the vms endpoint. Please refer to the vms POST documentation for how the complete VM spec has to be populated for creating a VM. Let’s look at examples around how the spec has to be populated when customizing guests.

The Journey to AHV Metro-Availability – Nutanix Blog

76324fdc-efb1-4588-83a2-eba738b0c512

This blog was authored by Tuhina Goel Product Marketing Manager Nutanix

This first blog in the three-part series on Metro Availability for AHV focuses on how to achieve zero data loss with Protection Policies in Prism Central at VM granularity.

For mission-critical applications in various industry sectors like banking, capital markets, insurance, healthcare, and emergency life support services, 24x7x365 uptime is key for the business to function unhindered. In such cases, applications need to have transparent visibility into underlying IT infrastructure failures, including hardware components (disk, network cards, power supply), racks, clusters, or sites. A 2014 Gartner study puts the cost of downtime at $5,600 per minute and can go as high as $540,000 per hour for mission-critical applications.

One of our core principles at Nutanix is to ensure the continuous availability of data for all applications running on the platform. To achieve seamless business continuity, we have built High Availability and Data Protection right into our AOS platform with the assumption that the hardware components are prone to failure. While this prevents customers from experiencing component failures in a cluster, what happens when entire clusters go down? The answer is Metro Availability. Metro Availability will extend the realm of continuous availability to another cluster. Customers can configure their deployments to seamlessly keeping mission-critical applications online even in the case of entire site failures.

Updated (again!): VM Reporting Script for Nutanix AHV/vSphere with Powershell — My Virtual Vision

After a great meeting with a current Nutanix customer they asked if we had a tool that could provide them with some more background on their current cluster utilization and report on that. While Prism/Prism Pro will give you excellent reporting I try to automate as much as possible so I decided to alter the
