**NOTICE FOR GITHUB**: This repository is a read-only mirror of the PVC repositories from my personal GitLab instance. Pull requests submitted here will not be merged. Issues submitted here will however be treated as authoritative.
## What is PVC?
PVC is a KVM+Ceph+Zookeeper-based, Free Software, scalable, redundant, self-healing, and self-managing private cloud solution designed with administrator simplicity in mind. It is built from the ground-up to be redundant at the host layer, allowing the cluster to gracefully handle the loss of nodes or their components, both due to hardware failure or due to maintenance. It is able to scale from a minimum of 3 nodes up to 12 or more nodes, while retaining performance and flexibility, allowing the administrator to build a small cluster today and grow it as needed.
PVC is a virtual machine-based hyperconverged infrastructure (HCI) virtualization cluster solution that is fully Free Software, scalable, redundant, self-healing, self-managing, and designed for administrator simplicity. It is an alternative to other HCI solutions such as Harvester, Nutanix, and VMWare, as well as to other common virtualization stacks such as ProxMox and OpenStack.
PVC is a complete HCI solution, built from well-known and well-trusted Free Software tools, to assist an administrator in creating and managing a cluster of servers to run virtual machines, as well as self-managing several important aspects including storage failover, node failure and recovery, virtual machine failure and recovery, and network plumbing. It is designed to act consistently, reliably, and unobtrusively, letting the administrator concentrate on more important things.
PVC is highly scalable. From a minimum (production) node count of 3, up to 12 or more, and supporting many dozens of VMs, PVC scales along with your workload and requirements. Deploy a cluster once and grow it as your needs expand.
As a consequence of its features, PVC makes administrating very high-uptime VMs extremely easy, featuring VM live migration, built-in always-enabled shared storage with transparent multi-node replication, and consistent network plumbing throughout the cluster. Nodes can also be seamlessly removed from or added to service, with zero VM downtime, to facilitate maintenance, upgrades, or other work.
PVC also features an optional, fully customizable VM provisioning framework, designed to automate and simplify VM deployments using custom provisioning profiles, scripts, and CloudInit userdata API support.
Installation of PVC is accomplished by two main components: a [Node installer ISO](https://github.com/parallelvirtualcluster/pvc-installer) which creates on-demand installer ISOs, and an [Ansible role framework](https://github.com/parallelvirtualcluster/pvc-ansible) to configure, bootstrap, and administrate the nodes. Once up, the cluster is managed via an HTTP REST API, accessible via a Python Click CLI client or WebUI.
Just give it physical servers, and it will run your VMs without you having to think about it, all in just an hour or two of setup time.
## What is it based on?
The core node and API daemons, as well as the CLI API client, are written in Python 3 and are fully Free Software (GNU GPL v3). In addition to these, PVC makes use of the following software tools to provide a holistic hyperconverged infrastructure solution:
* Debian GNU/Linux as the base OS.
* Linux KVM, QEMU, and Libvirt for VM management.
* Linux `ip`, FRRouting, NFTables, DNSMasq, and PowerDNS for network management.
* Ceph for storage management.
* Apache Zookeeper for the primary cluster state database.
* Patroni PostgreSQL manager for the secondary relation databases (DNS aggregation, Provisioner configuration).
The major goal of PVC is to be administrator friendly, providing the power of Enterprise-grade private clouds like OpenStack, Nutanix, and VMWare to homelabbers, SMBs, and small ISPs, without the cost or complexity. It believes in picking the best tool for a job and abstracting it behind the cluster as a whole, freeing the administrator from the boring and time-consuming task of selecting the best component, and letting them get on with the things that really matter. Administration can be done from a simple CLI or via a RESTful API capable of building full-featured web frontends or additional applications, taking a self-documenting approach to keep the administrator learning curvet as low as possible. Setup is easy and straightforward with an [ISO-based node installer](https://git.bonifacelabs.ca/parallelvirtualcluster/pvc-installer) and [Ansible role framework](https://git.bonifacelabs.ca/parallelvirtualcluster/pvc-ansible) designed to get a cluster up and running as quickly as possible. Build your cloud in an hour, grow it as you need, and never worry about it: just add physical servers.
