UCS is a reliable, pre-configured Linux server operating system featuring: Active Directory-like domain services compatible with Microsoft Active Directory; a mature and easy-to-use Web-based management system for user, rights, and infrastructure management; a scalable underlying concept suited for single server scenarios as well as to run and manage thousands of clients and servers for thousands of users within one single UCS domain; an app center providing single-click installation and integration of many business applications from 3rd parties and Univention; management capabilities to manage Linux- and UNIX-based clients; and command line, scripting interfaces, and APIs for automatization and extension. Its purpose is to provide Microsoft Server-like services on the cloud or on the premises, to run and operate corporate IT environments with Windows- and Linux-based clients, and to extend those environments with proven enterprise software.
Q-Tubes is a Web-based QEMU/KVM machine manager in Python built around the Pyramid Web framework. Its goal is to allow management of QEMU/KVM networks across single host instances, and ultimately across server farms. It supports minimal VM instances with disk support and basic network configuration (no user-space network yet), and basic VDE switch configurations. It provides a WSGI interface for deployment behind WSGI-aware servers, or provides its own basic server (python-waitress) for simple instances. The application is under steady development and has a moderate number of (Python) dependencies. Installation in a virtualenv is strongly recommended. It requires QEMU/KVM, VDE, and Python 2.7 or later.
kvm-simple-init can perform the following actions on a KVM machine: start, stop, kill, and restart. It focuses on simplicity, and is fully implemented in just a few hundred lines of shell script. It is intended for people who do not want to run libvirt just for running a few VMs, or people who prefer to manage flat configuration files using their preferred configuration management system. It does not provide complicated configuration file format or parameters. Only two pieces of information are needed: a QEMU monitor port for the machine and the full KVM command line needed to start the machine (gives full configuration freedom). kvm-simple-init can be used directly as a system init script for starting all KVM machines on a host machine. Just drop it in /etc/init.d, and enable it with the tools provided by your UNIX distribution. kvm-simple-init was inspired by the init script of FreeBSD jails.
