Purpose: Cloonix is a KVM based virtual network creation framework.
License: The documentation describes Cloonix as an AGPLv3 suite of C software components.
Network topology: Users create networks from virtual machines, containers, and other items linked through Open vSwitch bridges, and view the topology on a graphical canvas.
Virtualization: Cloonix supports QEMU-KVM virtual machines and crun containers using ZIP files or directories as root filesystems.
Network elements: Its documented network items include NAT, host TAP and physical interfaces, links between Cloonix networks, and a packet transit item for dropping, shaping, or delaying traffic.
Integrations: The documentation names Open vSwitch, crun, QEMU-KVM, SPICE, and Wireshark as key external components.
Wi-Fi emulation: The documentation says Wi-Fi emulation uses vwifi between QEMU-KVM machines and the iw command to place a physical interface in a container namespace.
Inspection: Users can open a Wireshark spy for supported interfaces, which can display or save packet captures but is not the complete Wireshark application.
Remote access: The documentation says the server connection is a TCP stream protected by a password.
Installation choices: The project offers a bundle installation requiring administrative privileges and a cloonix-toy installation that does not require root or administrator privileges.
Host platform: The project README describes Cloonix as a user-land application that needs a Linux distribution to run.
Release: The official homepage lists version 53.01 dated November 4, 2025 as the latest version.
Maintainer: The official homepage lists Vincent Perrier and provides the contact address [email protected].
