<h3>What is this?</h3>
|
||
|
<p>
|
||
|
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.
|
||
|
</p>
|
||
|
<p>
|
||
|
The aims of this project are:
|
||
|
<ul>
|
||
|
<li>Base OS Agnostic. If it can run libvirtd, this should be able to control it on some level</li>
|
||
|
<li>Open source, always</li>
|
||
|
<li class="notimpl">Control the Virtual Machine life cycle on one or more libvirtd hosts</li>
|
||
|
<li class="notimpl">Add clusting capabilities to libvirtd host, including;</li>
|
||
|
<li class="notimpl">Migration of VMs</li>
|
||
|
<li class="notimpl">Syncronizing secrets</li>
|
||
|
<li class="notimpl">Syncronizing VLANs, bridges, host only networking</li>
|
||
|
<li class="notimpl">Sharing HA storage availability</li>
|
||
|
<li class="notimpl">Locking shared resources like disks</li>
|
||
|
<li class="notimpl">Starting VMs marked for HA on another host when one goes down</li>
|
||
|
<li class="notimpl">Manage a library of Cloud-init resources and templates to build new VMs quickly</li>
|
||
|
<li class="notimpl">Local Storage management, including local directory, lvm, zfs (if installed)</li>
|
||
|
<li class="notimpl">Advanced Storage management, such as Ceph, glusterfs, drbd, iscsi, nfs</li>
|
||
|
<li class="notimpl">Storage syncronization of local disks between hosts (zfs snapshots, lvm snapshots, rsync)</li>
|
||
|
<li class="notimpl">Backup scheduling, creation, restoration</li>
|
||
|
</ul>
|
||
|
</p>
|
||
|
<p>
|
||
|
What this project does not, but may someday do (future goals):
|
||
|
<ul>
|
||
|
<li>Install the OS which libvirtd is running on</li>
|
||
|
<li>Install/provision libvirtd on a host that does not have it installed</li>
|
||
|
<li>Tools to move from one vendor to clustvirt/libvirtd</li>
|
||
|
<li>VM templates for common aspects of VM creation and management, like appliances</li>
|
||
|
<li>External tool access that can be used to manage things that are not managed here (cephadm dashboard, for instance)</li>
|
||
|
</ul>
|
||
|
</p>
|
||
|
<p>
|
||
|
What this project will NEVER do, even if asked really nicely:
|
||
|
<ul>
|
||
|
<li>Kubernetes</li>
|
||
|
<li>Application container management (docker, podman, etc)</li>
|
||
|
<li>Become an OS</li>
|
||
|
<li>Have a paywall</li>
|
||
|
<li>Vendor lock-in</li>
|
||
|
<li>Become a commercial entity (even indirectly)</li>
|
||
|
<li>Anything that does not have an Open Source standard behind it</li>
|
||
|
<li>Directly control a guest Operating System</li>
|
||
|
</ul>
|
||
|
</p>
|
||
|
<p>
|
||
|
Why does this even exist?
|
||
|
<ul>
|
||
|
<li>Broadcom buying VMWare, and VMWare losing a free teir for homelabbers pissed me off</li>
|
||
|
<li>Vendor lock-in pisses me off</li>
|
||
|
<li>Even good open source Hyperconverged systems (Proxmox, as an example) exhibit a form of vendor lock-in</li>
|
||
|
<li>Libvirt is terrific, has the functionality for everything those other providers do, but there really is not a
|
||
|
great option for those dipping their toes into Open Source</li>
|
||
|
<li>Its fun to build things that solve a need</li>
|
||
|
<li>I really want to do it</li>
|
||
|
</ul>
|
||

|
<p>I recently created a <a href="http://redd.it/1bct15z">post</a> 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??"</p>
|
||
|
<p>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.</p>
|
||
|
<p>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.</p>
|
||
|
<p>I will not let that happen here</p>
|
||
|
<p>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.</p>
|
||
|
<p>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.<p>
