| Integrations | Standard hooks can provide NVIDIA GPU support and inject Mellanox host MOFED for InfiniBand HCA support into containers. | The comparison page lists OpenVZ API for Ruby and LibVirt. |
| Isolation | Enroot uses Linux user and mount namespaces and provides little to no isolation while preserving filesystem separation. | The features page says containers are isolated from one another across filesystems, processes, IPC, and sysctl variables. |
| Purpose | Enroot turns traditional container and OS images into unprivileged sandboxes. | OpenVZ provides container based virtualization for Linux, allowing multiple isolated containers to run on one physical server. |

In their own words
Enroot
Enroot is a free, open-source Linux command-line utility that turns traditional container and operating-system images into unprivileged sandboxes. It is aimed at high-performance or virtualized environments where portability and reproducibility matter and additional isolation is not required. Enroot runs without a daemon and supports unprivileged multi-user use without a setuid binary. Linux user and mount namespaces preserve filesystem separation, while the project provides little to no isolation. The command line covers batch, bundle, create, exec, export, import, list, remove, and start operations. It imports known formats including Docker, with the README reporting a 3x to 5x speedup for large Docker-image imports. Built-in GPU support uses libnvidia-container, and hooks can add NVIDIA support or Mellanox host MOFED. Runtime settings come from enroot.conf or higher-priority environment variables. Standard and hardened package flavors are available.
