[UPDATE]

English/short:

Linux-VServer provides virtualization for GNU/Linux systems. This is accomplished by separating the kernel into contexts. All contexts run in the same kernel, what makes this virtualization technique very efficient. The field of application ranges from running a single processes to a complete instance of a distribution.

German/kurz

Linux-VServer erlaubt es, komplette GNU/Linux Systeme zu virtualisieren. Dies wird durch eine Isolation auf Kernelebene erreicht. Die dadurch entstehenden Kontexte sind voneinander getrennt und ermöglichen den Betrieb mehrerer virtueller Einheiten. Diese laufen in einen gemeinsamen Kernel, wodurch eine effiziente Nutzung der Resourcen erreicht wird. Kontexte koennen ganz unterschiedlich ausgepraegt sein: von einzelnen Prozessen bis zu ganzen Distributionen.

English

short:

Linux-VServer is for running multiple instances of GNU/Linux distributions with a single kernel. The instances are strictly separated form each other by context isolation. All contexts use the same kernel, which makes this virtualization technique very efficient. The field of application ranges from running single processes in their own context to complete virtual private servers. With many distributions it is possible to run them unmodified in a context.

Linux-VServer is for running multiple instances of GNU/Linux on a single machine. The instances are strictly separated form each other by a technique called context isolation, which offers a very fine granularity in assigning access rights and restrictions to the resources of the machine. It is possible to share CPU, RAM, Disk I/O, Diskspace and networking in a soft way as well as set limits to particular contexts and assign quotas.

The contexts themselves are robust enough to boot many Linux distributions unmodified, including Debian and Fedora Core. Creating the contexts simply requires a Linux-VServer patched kernel and a set of userspace tools. Creating a context is similar to creating a choot environment - but much more secure.

All instances use same kernel, which makes this virtualization technique very efficient. The field of application ranges from running single processes in their own context for security reasons to complete virtual private server environments or even multi-headed desktop systems. Virtual private servers are commonly used in web hosting services, where they are useful for segregating customer accounts, pooling resources and containing any potential security breaches.

German

kurz

Linux-VServer erlaubt es ein GNU/Linux System zu virtualisieren indem es in Kontexte unterteilt wird. Die Kontexte sind streng voneinander getrennt, teilen sich jedoch einen gemeinsamen Kernel, was die Virtualisierung sehr effizient macht. Die Kontexte können dabei verschieden ausgeprägt sein, von der Ausführung eines einzelnen Prozess bis hin zu Instanzen kompletter Distributionen.
