Linux-VServer is a virtualization solution for Linux operating systems that provides a lightweight and efficient virtual machine architecture. It allows the creation of multiple virtual servers, or virtual private servers (VPS), on a single physical server, enabling isolation and resource management for different applications and users.
At its core, Linux-VServer utilizes the concept of operating system-level virtualization, also known as containerization. Instead of running full-fledged virtual machines, Linux-VServer leverages the Linux kernel's features to partition the operating system and resources, providing separate environments for each virtual server.
The general architecture of LinuxVServer.
VServer provides a shared, virtualized OS image, consisting of a root file system, and a shared set of system libraries and kernel services. Each VM can be booted, shut down, and rebooted independentlythree groupings of software running on the computer system. The hosting platform includes the shared OS image and a privileged host VM, whose function is to monitor and manage the other VMs. The virtual platform creates virtual machines and is the view of the system seen by the applications running on the individual VMs.
The key components of Linux-VServer architecture include:
1: Kernel-level virtualization
2: Contexts
3: Resource management
4: Security and isolation
5: Efficient performance
