What is this?

+

+ Clustvirt (work in progress name) aims to be the agnostic cluster controller for libvirtd. + The server component is used to display both the WebUI and run the REST API used to control one to many + libvirtd hosts to manage virual machines, LXC containers (through libvirtd), gather information about + each host, and monitor each host. +

+

+ The aims of this project are: +

+

+

+ What this project does not, but may someday do (future goals): +

+

+

+ What this project will NEVER do, even if asked really nicely: +

+

+

+ Why does this even exist? +

+

+

I recently created a post on reddit announcing that I was building this, + and while the majority of responses were supportive, even offering features that may enhance what I originally + set out to do, many responded with "Why do we need another one??"

+

Besides the list above about why this exists, I wanted to clarify a few things those individuals did not seeem to + get: This is not a rebuild of Proxmox, Cloudstack, VMWare, Harvester or any of the other "Hyper-converged + Infrastructer Operating System" offerings out there. This will not take over your base operating system machine, just + act as a cluster manager and interface to access the existing libvirtd instances on those machines, nor will it + prescribe a set of requirements that make it hard to move your own infrastructure around.

+

At the heart of this project is that I hate the enshitifiation of Open Source that has been going on, where its + just another way to make money and control the eco system. RedHat tried to do it by locking down their source code, + Proxmox does it by making sure anything you do on Proxmox is tied to Proxmox (no offense to Proxmox), and even + Hashicorp, who I loved so dearly, changed from a pure Open Source licensing model to one that protects the business + over the community.

+

I will not let that happen here

+

This project will seek to use the Unix philosophy, of building off of existing standards, combining tools, and + having one tool do one job well. This does not mean there will be one application for each aspect of the job, but + that this application stack will manage Libvirtd well, and have individual and configurable paths to manage each + sub aspect of the libvirt stack. This stack will not create a Ceph cluster for you, it leaves you to do that. It + will not even talk to a ceph cluster. It will, however, let you add that cluster via configuration options to define + it as a storage pool that libvirt can use.

+

If you want something that will allow you to use a single interface to create all sub aspects that can be used by + libvirt (managing all firewall rules, creating a ceph cluster, etc.), use something like Proxmox which includes + that builtin functionality. This isn't the stack for you.
