By carefully following the guidelines for acquiring, transferring, and setting permissions for your images, you can construct and scale highly complex and realistic network environments right from your browser. If you are just getting started, I can help you:
Connect to your EVE-NG IP address using WinSCP via SFTP (Port 22). Navigate to the QEMU directory: /opt/unetlab/addons/qemu/ .
: Ensure your local hard drive is not at 100% capacity. EVE-NG creates temporary copy-on-write files for running nodes and will fail if storage is full. Eve-ng Images Download
This is almost always caused by forgetting to run the permission fix script. Run /opt/unetlab/wrappers/unl_wrapper -a fixpermissions in the CLI.
Because many of these images are proprietary, they are generally not hosted directly on the EVE-NG website. Users usually find them through: 1. Official Vendor Sites (Recommended) : Ensure your local hard drive is not at 100% capacity
You can purchase a Cisco Modeling Labs (CML) subscription. This grants legal access to download the latest Cisco IOSv, IOSv-L2, ASAv, NX-OSv, and XRv images, which work flawlessly inside EVE-NG.

Typically distributed as .qcow2 , .vmdk , or .iso files. 2. Cisco IOL / IOU Images
EVE-NG supports three primary categories of images. Each serves a different purpose and requires a specific directory structure.
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. However, without images, the canvas remains blank. 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.
