This openQRM plugin integrates the Linux-VServer virtualization technology.
Linux-VServer provides virtualization for GNU/Linux systems. LVS is a soft partitioning concept based on Security Contexts which permits the creation of many independent Virtual Private Servers (VPS) that run simultaneously on a single physical server at full speed, efficiently sharing hardware resources.
A VPS provides an almost identical operating environment as a conventional Linux server. All services, such as ssh, mail, web and database servers can be started on such a VPS, without (or in special cases with only minimal) modification, just like on any real server.
Each VPS has its own user account database and root password and is isolated from other virtual servers, except for the fact that they share the same hardware resources.
