At its core, EVE-NG functions as an orchestrator. It provides the graphical user interface, the wiring logic, and the underlying Linux infrastructure to manage virtual machines.

An "image" in this context is a virtual hard disk file—typically in QEMU (Quick Emulator) format—containing an operating system such as Cisco IOS, Palo Alto Networks PAN-OS, Juniper Junos, or Linux distributions. The process of downloading and importing these images transforms the software from an empty shell into a dynamic lab environment where routing protocols, firewall policies, and SDN controllers can be configured and tested.
