LXC Linux Containers vs OpenVZ

LXC Linux Containers — LXC Linux Containers (LXC) provides lightweight, operating system-level virtualization on Linux. It allows running multiple isolated Linux systems on a single host with minimal resource overhead.

OpenVZ — OpenVZ is an open source container-based virtualization platform for Linux. It allows multiple isolated virtual containers to run on a single physical server, sharing the same Linux kernel.

LXC Linux Containers offers OS-level virtualization for running multiple isolated Linux systems on a single host, Resource isolation of CPU, memory, block I/O, network, etc, Near-native performance with minimal overhead, Live migration of containers between hosts, Snapshots and cloning of containers, while OpenVZ provides OS-level virtualization, Resource isolation, Overcommitting of physical resources, Live migration of containers, Templates for fast deployment.

LXC Linux Containers stands out for Lightweight and efficient resource utilization, Near-native performance compared to full virtualization, Easy to deploy and manage at scale; OpenVZ is known for Lightweight and efficient, Good performance, Easy to manage.
