Turn a Raspberry Pi into a DLNA server

I recently bought myself an Apple TV. Absolutely amazing piece of design and technology but ... movies on the Apple Movies platform are (very) expansive. And what about my actual collection of video files ? There is no way to connect storage on the Apple TV. So, I needed to find a solution to play the movies files that I filmed with my camcorder on the Apple TV.
Actually, there is a way. The Apple TV AppStore is providing an app called InFuse. It allows you to play remote content. One of the supported protocol is DLNA. DLNA protocol is not new and usually well supported. It allows you to stream content over the network (local ideally to keep smooth broadcasting). You can find more details about DLNA here. For free, you can also use VLC for AppleTV. The user interface and functionalities are very light but if you don't need fancy menus and details about movies, this is a good start.

Somehow, the latest version of Nutanix AOS (starting at v5.5) integrated a bug in the protection domains management. You cannot remove a remote site without getting this message :


They know about the error and they are going to release a fix in v5.5.1. But so far, we need to use a workaround to complete this action.

Nutanix CE : How to create clones from command line

Sometimes, you need to create multiple clones for a single gold image (template). This can be boring using the Prism Element UI if you have more than 10. Hopefully, there is a set of commands that can be initiated from the command line ACLI - Acropolis CLI. ACLI is rich in terms of action that can be done. Actually almost everything VM related can be done using ACLI. Here is how to create clones from a source VM.

Nutanix CE : How to change host name

When deploying a Nutanix CE host, the host name is always weird and random. Something like "NTNX-010422a0-A". This is not easy for maintenance - especially when you have more than one host. You probably would like to call it with the matching name of your real host like NUC-1, Host-1. This is not complex here is how.

Nutanix CE : How to reduce the CVM memory

Most of the time when deploying Nutanix CE, the hardware is limited because you need to save costs. Then, maximum RAM is limited - like in the Intel NUC who can only support up to 32 GB. By default, the CVM are configured with 16 GB RAM, therefore this is giving less RAM for creating VMs. If you are not using advanced features like dedup on the flight or erasure coding, you can decrease the CVM memory to 8 GB without any impact on the cluster. This is what this guide is all about.
