API

• LibCT - Linux containers control plane.
• Parallels SDK - Parallels Virtualization SDK is a development kit used to create and integrate custom software solutions with Parallels Cloud Server. The SDK provides cross-platform ANSI C and Python APIs.
• LibVirt: there are two different drivers: driver with support of Parallels Hypervisor, works via Parallels SDK, and driver with support of OpenVZ containers.
• OpenVZ containers API for Ruby, sources

Configuration management

• Puppet module for legacy OpenVZ
• Flexiant
• Ansible module for legacy OpenVZ

Container management

• Docker: Docker inside VZ containers, Docker manage VZ containers via LibCT (see LibCT)
• Cobbler
• Webmin plugin
• Quattor - a system administration toolkit providing a powerful, portable, and modular set of tools for the automated installation, configuration, and management of clusters, farms, grids and clouds. See slides.
• Cloudmin - an UI built on top of Webmin for managing virtual systems, such as Xen, KVM and OpenVZ instances.
• SolusVM (Solus Virtual Manager) is a powerful GUI based VPS management system with full OpenVZ, Linux KVM, Xen Paravirtualization and Xen HVM support.
• Fabric - library and command-line tool for streamlining the use of SSH for application deployment or systems administration tasks.

Images registry

• Bitnami (Virtuozzo only)
• Turnkey in Proxmox VE

Hosting automation

• OpenStack (available in Kilo release) Source
• Nova plugin for legacy OpenVZ. See also Launchpad.
• Plesk (proprietary)
• Parallels Virtual Automation (proprietary)

Hosting offers

• Virtuozzo
• OpenVZ-based hosting

Monitoring

• Zabbix - enterprise-class monitoring solution for everyone.
• Nagios - is an open source computer system monitoring, network monitoring and infrastructure monitoring software application.
• ctop - a lightweight top like monitor for linux CGroups with Docker, LXC and OpenVZ support.
• htop - interactive process viewer for Linux.

Maintenance (migration, backup)

• CRIU (Checkpoint and Restore in Userspace) - software tool for Linux operating system. Using this tool, you can freeze a running application (or part of it) and checkpoint it to a hard drive as a collection of files. You can then use the files to restore and run the application from the point it was frozen at. The distinctive feature of the CRIU project is that it is mainly implemented in user space.
• Plan B - fast OpenVZ backups. Source code: https://github.com/gcoop-libre/plan-b. Slides "plan-b - fast OpenVZ backups".
• KernelCare - rebootless kernel updates (OpenVZ and Virtuozzo).

Network

• Open vSwitch (OpenVZ requires patch)
• Shorewall - is a gateway/firewall configuration tool for GNU/Linux.

OpenVZ-based Linux distros

• Cloud Linux - Linux distro providing LVE (Lightweight Virtual Environments).
• OWL (OpenWall Linux)
• Proxmox
• XtreemOS
• OpenNode - lightweight bare-metal cloud OS combining Linux Containers and KVM full virtualization options into payload optimized solution. Source code
• ALTLinux

PaaS (Platform-as-a-Service)

• Jelastic - PaaS based on Virtuozzo containers.

Storage

• Odin Cloud Storage (proprietary, free use with limitation 100 Gb)
• ZFS, see also

Useful scripts
