Common image types include:
: The image file corrupted during the SFTP transfer or the filename is incorrect.
: Each QEMU image must be in its own folder starting with a specific prefix (e.g., for Palo Alto, for Windows). Permissions Crucial Step.
fix the file permissions, or the nodes will fail to start. Run this command in the EVE-NG CLI: /opt/unetlab/wrappers/unl_wrapper -a fixpermissions Use code with caution. Copied to clipboard Naming Conventions: Download All Eve-ng Images
: Advanced users sometimes use tools or scripts (like those found in similar emulators like PnetLab) to "pull" images directly into the environment via SSH. Cloud Images
If you’re looking for a script or automation to organize images you already have rights to , I’m happy to help with that — just clarify what you actually need.
To begin, one must understand that EVE-NG is the engine, but the images are the fuel. These images generally fall into two primary formats: QEMU (KVM) and IOL (IOS on Linux). QEMU images are the modern standard, offering deep feature parity with physical hardware for devices like the Cisco ASA, Palo Alto firewalls, and Juniper vMX routers. IOL images, conversely, are lightweight alternatives that consume minimal CPU and RAM, making them ideal for massive switching and routing labs where resource conservation is paramount. While EVE-NG provides the framework to run these, the software itself does not come pre-loaded with proprietary operating systems due to legal and licensing restrictions. Common image types include: : The image file
In conclusion, while the prospect of downloading "all" EVE-NG images is a common goal for many enthusiasts, success lies in the quality and legal integrity of the library rather than just its size. By mastering the technical requirements of QEMU/IOL management and adhering to vendor licensing, professionals can transform EVE-NG into a powerful, career-defining tool. The ability to spin up a multi-vendor data center on a single laptop remains one of the most significant advancements in modern technical education.
If you are building a "Master Lab," ensure you have downloaded these essentials: Essential for CCNA/CCNP.
Developers often share automation tools and "naming tables" (e.g., hegdepavankumar/Cisco-Images-for-GNS3-and-EVE-NG ) that provide links to collections hosted on external drives, though these links may frequently expire. fix the file permissions, or the nodes will fail to start

Connect to your EVE-NG server using an SSH client like PuTTY or terminal.
Before we dive into the "how," let’s clarify the "what." An "image" in EVE-NG terms is a virtual disk file (usually .qcow2 , .img , or .vmdk ) that contains a network operating system.
Once you have downloaded your images, you cannot just drop them into a folder. EVE-NG requires a specific directory structure. Step-by-Step Installation:
