In their own words
Cloonix
Cloonix is a free, AGPLv3 suite of C software components for creating virtual networks with KVM-based virtual machines and containers. It runs as a user-land application on a Linux distribution, with a web platform also listed. Users assemble machines, containers, and network items, connect them through Open vSwitch bridges, and view the topology on a graphical canvas. Virtual machines use QEMU-KVM; crun containers can use ZIP files or directories as root filesystems. Elements include NAT, host TAP and physical interfaces, links between Cloonix networks, and packet transit for dropping, shaping, or delaying traffic. The project names Open vSwitch, crun, QEMU-KVM, SPICE, and Wireshark as key components. A Wireshark spy can display or save captures on supported interfaces but is not the complete Wireshark application. Wi-Fi emulation uses vwifi and iw. Installation offers a privileged bundle or cloonix-toy without root requirements. The homepage lists version 53.01, dated November 4, 2025.
