description OpenVZ Overview

OpenVZ is a Linux distribution that utilizes kernel virtualization, allowing multiple isolated operating system environments – known as private servers – to run concurrently on a single physical host, offering resource control and security features.

help OpenVZ FAQ

What operating system does OpenVZ virtualize?

OpenVZ virtualizes Linux environments by sharing one host kernel. Its containers are commonly called virtual private servers or VPSs.

How is OpenVZ different from a full virtual machine?

OpenVZ containers share the host’s Linux kernel, while technologies such as KVM can run separate guest kernels. This makes OpenVZ lightweight but less flexible for mixed operating systems.

Can OpenVZ run Windows guests?

Traditional OpenVZ is designed for Linux containers and cannot run a normal Windows guest operating system. A hardware virtualizer such as KVM is more suitable for Windows virtual machines.

What replaced OpenVZ in many modern Linux hosting setups?

Many deployments moved toward Virtuozzo, LXC, or systemd-nspawn-based containers. OpenVZ 7 was reworked under the Virtuozzo platform rather than remaining the same older project.
