How to Change CVM Memory in Nutanix CE Platform

By | 15/12/2018
0 Comment

In last post of this series, I covered installation of Nutanix CE single-node cluster. In this post i will walk through steps of reducing CVM memory.

By default when you deploy Nutanix CE, CVM is configured with 16 GB RAM. You can verify this by logging into Prism and navigating to Home > VM view.

Or you can SSH to AHV host and type command : virsh dominfo

Now suppose you allocated 20 GB RAM to the VM where Nutanix CE is installed, CVM will consume 16 GB out of it, leaving only 4 GB for the AHV host. But we can reduce CVM memory to 12G or 8G for lab purpose. read more

In last post of this series we discussed about lab setup that is needed to deploy the Nutanix CE platform. In this post we will learn about how to deploy a single node cluster.

If you are not following along this series, then I recommend reading earlier posts of this series from below links:

1: Nutanix Community Edition Introduction

2: Lab Setup

In last post we converted our centos VM to a template to save deployment time. I deployed a new VM from the template and booted it. 

Once the “init image” is loaded at the login, type “install” command to proceed. read more

In last post of this series we discussed about what Nutanix CE is what does it offer and we talked about limitation of the product. In this post I will walk through my lab setup which I used to deploy the Nutanix CE.

Recommended Hardware

Before planning your deployment, make sure to refer to below spreadsheet which lists all necessary piece of hardware you need to have in place.

In my lab, I don’t have a dedicated hardware server for deployment, so I went ahead with Nested virtualization technique. But if you are interested in deploying CE on dedicated piece of hardware then I would recommend reading this article. read more

My HCI Lab with Nutanix Community Edition: Part 1: Introduction

Till the time I was working majorly on VMware products, I thought there can’t be a better piece of technology than this. But since the time I started learning Nutanix, my thoughts changed and I must admit that I am in awe of this product.

To learn any new product, home lab is the best place where you can learn things from scratch. Since I don’t have dedicated hardware pieces to deploy Nutanix, I tried my hands on Nutanix Community Edition.

In this post I will outline some basic considerations which you should keep in mind when when planning to go with Nutanix CE and will walk through the steps needed to create lab. Also I will discuss possibilities and limits of using this product. read more

By default when vRNI 3.9 is installed, it starts in the NSX assessment mode and in this mode you will only see option to add vCenter server as data source.

VMware vCloud Availability for Cloud-to-Cloud DR is the latest addition in VMware Cloud Provider Platform portfolio and it was first released in May 2018 and it brought joy for the service providers who wanted a VMware native Cloud to Cloud DR solution for vCloud Director based clouds from long time. 

What is vCloud Availability for Cloud-to-Cloud DR (vCAV-C2C)?

VMware vCloud Availability for Cloud-to-Cloud is a solution for DR between 2 instances of vCloud Director. Cloud to Cloud DR concept is not new but VMware did not had any solution for vCloud based cloud. vCAV-C2C fills this gap and helps VMware Cloud Providers to leverage existing vCloud Director environments to provide DR services, including replication and failover capabilities for workloads at both VM and vApp level. read more
