Proxmox – open-source server virtualization management platform

Proxmox Virtual Environment is an open-source server virtualization management platform.

It is a Debian-based Linux distribution with a modified Ubuntu LTS kernel and allows deployment and management of virtual machines and containers.

Proxmox VE includes a web console and command-line tools, and provides a REST API for third-party tools. Two types of virtualization are supported: container-based with LXC, and full virtualization with KVM. It comes with a bare-metal installer and includes a web-based management interface.

Features include:

  • Maximum flexibility to your production environment.
  • Easy management of compute, network, and storage with the central web interface.
  • 100% software-defined architecture.
  • Two virtualization technologies supported: KVM hypervisor & Linux Container (LXC). Use KVM full virtualization for Windows and Linux images, and lightweight containers to run conflict-free Linux applications.
  • Web-based Management Interface:
    • Integrated – no need to install a separate management tool or any additional management node.
    • Fast, search-driven interface, able to handle thousands of VMs.
    • Based on the Ext JS JavaScript framework.
    • Secure HTML5 console, supporting SSL.
    • Let’s Encrypt TLS certificates via the DNS-based challenge mechanism (or http).
    • Fast and easy creation of VMs and containers.
    • Seamless integration and easy management of a whole cluster.
    • Subscription management via GUI.
      Integrated documentation
  • Rest API:
    • Easy integration for third-party management tools.
    • REST like API (JSON as primary data format).
    • Easy and human readable data format (native web browser format).
    • Full support for API tokens
    • Automatic parameter verification (verification of return values).
    • Automatic generation of the API documentation.
    • Easy way to create command line tools (use the same API).
    • Resource Oriented Architecture (ROA).
    • Declarative API definition using JSON Schema.
  • Command Line:
    • Manage all components of your virtual environment.
    • CLI with intelligent tab completion.
    • Full UNIX man page documentation.
  • High-Availability (HA) Cluster Manager:
    • No single point of failure (no SPOF).
    • Multi-master cluster.
    • Manage the HA settings for KVM and LXC via GUI.
    • pmxcfs—unique Proxmox VE Cluster File System: database-driven file system for storing configuration files replicated in real-time on all nodes using Corosync.
    • Based on proven Linux HA technologies, providing stable and reliable HA service.
    • Resource agents for KVM and containers (LXC).
    • Watchdog-based fencing.
  • Live Migration.
  • Built-in services: firewall, backup/restore, storage replication, etc.
  • Software-defined storage:
    • Local storage such as ZFS (encryption possible), LVM, LVMthin, ext4, and XFS.
    • Shared storage such as FC, iSCSI or NFS.
    • Distributed storage such as Ceph RBD or CephFS.
    • Encryption support for Ceph OSD and ZFS.
    • Unlimited number of storage definitions (cluster-wide).
  • Complete open-source platform for enterprise virtualization.
  • Live migration
  • Storage replication stack.
  • Virtualized networking:
    • Bridged networking model.
    • Each host with up to 4094 bridges.
    • TCP/IP configuration.
    • IPv4 and IPv6 support.
    • VLANs.
    • Open vSwitch.
  • Hyper-converged infrastructure (HCI) with Ceph.
  • Proxmox VE Firewall:
    • Supporting IPv4 and IPv6.
    • Linux-based netfilter technology. Stateful firewall, provides high bandwidth.
    • Distributed: main configuration in Proxmox VE cluster file system, iptable rules are stored in nodes.
    • Cluster-wide settings.
    • 3 levels of configuration (data center, host, VM/CT).
    • Support for ‘raw’ tables; enable Synflood-Attack protection.
  • Backup and restore:
    • Full backups of VMs and containers.
    • Live snapshot backups.
    • Multiple schedules and backup storage.
    • GUI integrations, but also via CLI.
    • “Backup Now” and restore via GUI.
    • Run scheduled backup jobs manually in the GUI.
    • All jobs from all nodes can be monitored via the GUI tab “Tasks”.
    • Back up VMs with IOThreads enabled.
  • Two-factor authentication.
  • Multiple authentication sources:
    • Linux PAM standard authentication (e.g., ‘root’ and other local users).
    • Built-in Proxmox VE authentication server.
    • Microsoft Active Directory (MS ADS).
    • LDAP.
  • Role-based administration:
    • User and permission management for all objects (VMs, storage systems, nodes, etc.)
    • Proxmox VE comes with a number of predefined roles (lists of privileges) which satisfies most needs.
    • The GUI provides an overview the whole set of predefined roles.
    • Permissions to control access to objects (access control lists). In technical terms they are simply a triple containing <path,user,role>. Each permission specifies a subject (user or group) and a role (set of privileges) on a specific path
