## Core Features
### Overall/Nodes
* Host-level redundancy
* N-1 fault tolerance
* Cluster- and node-level alerting
* Stable base operating system (5+ year support)
* Convenient, holistic view of the cluster (resources, devices, VMs, etc.) via CLI and API
* Deployment, management, updates, and base OS upgrades via straightforward Ansible playbooks
* Cluster-level backup and restore
* Node hot add/remove from service (flush/unflush/restore) for maintenance
* Automatic fencing of unresponsive node(s) and recovery of affected VMs (conditional)
* Cluster maintenance state (allows monitoring/alerting pause while performing maintenance)
* Includes Munin and CheckMK monitoring plugins
### Virtual Machine Management
* Full VM lifecycle management (start/stop/restart/shutdown/disable)
* Live-migration (zero-downtime move) of VMs between nodes
* Automatic restarting of failed VMs
* (For supporting VMs) Serial console logging with interactive follow
* VNC console with flexible listen directives
* Simple resource management (vCPU/memory) w/restart
* Hot attach/detach virtual NICs and block devices
* Tag support for organization/classification
* VM hot/online backup creation, management (delete), and quick restore to external storage
### Network Management
* Bridged (vLAN), Managed (VXLAN), and Direct (SR-IOV) VM networks
* Consistent network view (all nodes are provisioned with all networks) for Bridged and Managed VM networks
* DHCP, DNS, NTP, and TFTP for Managed VM networks
* Upstream BGP for route learning for Managed VM networks
### Storage Management
* Distributed & replicated storage backend (Ceph Object Store) with high availability and node-level redundancy
* Shared storage for VM storage volumes/virtual disks (Ceph RBD)
* Integrated monitoring and alerting into PVC frontend
* Zero-cost snapshots
* Flexible replication conigurations for large or complex clusters
### Provisioning
* Integrated, highly flexible VM provisioning system
* Define custom install scripts or use included examples for common OSes
* CloudInit Amazon EC2-compatible CloudInit "userdata" support
* Define dynamic VM profiles from component templates (system, network, disk), scripts, and userdata.
* OVA VM image support
* Volume cloning support (cloning VMs)
### Other
* Free, Libre and Open Source (FLOSS) software
* Written in modern Python3
* Well-maintained and frequently updated
## Building Blocks ## Building Blocks
PVC itself is a series of software daemons (services) written in Python 3, with the CLI interface also written in Python 3, designed to glue other FLOSS tools together in order to provide a consistent cluster operation and management experience.
