Cloonix vs IMUNES

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.

IMUNES is a free multiprotocol emulator and simulator for general-purpose IP network experiments on FreeBSD and Linux. The project says a single physical machine can run hundreds to thousands of virtual nodes. Its GUI helps create and configure nodes and links, and each node has its own IPv4, IPv6, IPsec, socket and firewall configuration and address space. Link controls can introduce delay, bit errors, duplication and bandwidth limits. Standard UNIX APIs are preserved, so BSD and Linux binaries can run unmodified. On Linux it uses Docker for virtual nodes; on FreeBSD it uses jails and netgraph. The project says experiments can be instantiated in seconds and use hardware resources efficiently. Downloads include public source repositories, examples, security scenarios, manuals and VMware and VirtualBox images. Linux use requires kernel version 3.10 or newer and the Docker daemon; the README also instructs users to run experiments as root. The listed latest image is IMUNES-FreeBSD-14.3-RELEASE (BETA), a 4GB amd64 OVA. The project describes JSON configuration and live changes to nodes, interfaces and links during a running experiment.
