VM Performance Stats with Nutanix REST API

One of the most common questions I get from my Nutanix colleagues, as well as customers and partners, is "How do I use the Nutanix API to get VM performance statistics?" Before digging into exactly how we do that, let's take a quick look at how things stand today. And...

Nutanix – VM Customisation with Cloud-Init

Intro Recently Nutanix extended the already-powerful Nutanix Acropolis Hypervisor (AHV) software by adding the ability to natively leverage cloud-init and Sysprep VM customisation. This means we can still use Prism to create & manage our AHV VMs but we can also take a...

CentOS 7, DNS and firewalld

Yesterday I needed to setup a local DNS server. Sure, I could've used Windows but, mostly for licensing reasons, decided that using a free OS would be a much better idea. For various reasons I used to go with CentOS 7, the latest version of the CentOS Project Linux...

Debian LAMP dev server (and that’s it)

Another one? Really? I’ll be the first to admit there there is a huge number of documents, websites, tutorials and guides already available for what I’d say is one of the most common questions from web developers: “How do I setup my own Linux web development server?”...

JavaScript refactoring, the n00b way
