Vendor image files are often 1GB to 4GB+.

While torrents claiming "EVE-NG 1000+ images" exist, they are:

Before you click any download link, you need to understand the architecture. EVE-NG uses two primary types of images:

Pro Tip: For modern CCIE studies, IOL (Layer 2/3 switching) and QEMU (vEOS, vMX, FortiGate) are what you need.

Searching for “Download EVE-NG images” is the natural first step for any engineer building a virtual lab. But the secret is that EVE-NG does not host the images—it simply runs them.

The workflow is: Vendor → License → RAW Image → Upload → Convert → Permissions → Run.

By following the legal and structured approach outlined in this guide, you will build a stable, professional, and copyright-compliant EVE-NG lab. Start by registering for free trials at Cisco DevNet, Juniper vLabs, or Arista.com. Then, use the step-by-step upload guide above. Within an hour, you will have a fully functioning virtual network.

Remember to run fixpermissions after every image upload, and always verify the disk naming convention for your specific node type.

Do you have a specific image that won’t boot? Describe the error in the EVE-NG community forums, and include the output of /opt/unetlab/wrappers/qemu_wrapper -v for the best help.

Mastering Your Virtual Lab: A Complete Guide to EVE-NG Images

If you are pursuing a career in network engineering, you already know that theory only gets you so far. To truly understand how OSPF converges, how BGP scales, or how a Palo Alto firewall filters traffic, you need hands-on practice. EVE-NG (Emulated Virtual Environment Next Generation) is the gold standard for this, but the platform itself is just an empty shell without one critical component: Images.

Finding, downloading, and installing the right EVE-NG images is the most common hurdle for beginners. This guide breaks down everything you need to know to build your virtual powerhouse. What are EVE-NG Images?

In the context of EVE-NG, an "image" is a virtualized version of a hardware device's operating system. Instead of having a physical Cisco Catalyst switch on your desk, you run a Cisco IOL (IOS on Linux) or QCOW2 image that mimics the hardware's behavior exactly. Types of Images Supported: Dynamips: Older Cisco IOS images (mostly legacy).

IOL (IOS on Linux): Lightweight, high-performance Cisco images used internally by Cisco engineers.

QEMU/KVM: The modern standard. This includes almost everything else: Arista, Juniper, CheckPoint, Palo Alto, Windows/Linux hosts, and F5 Load Balancers. Where to Download EVE-NG Images

This is the "million-dollar" question. Due to licensing and copyright laws, EVE-NG does not provide vendor images (Cisco, Juniper, Fortinet, etc.) with the software. 1. The Official Route (Recommended)

The safest and most legal way to acquire images is directly from the vendors.

Cisco: Use a Cisco Modeling Labs (CML) subscription. It provides legal access to IOSv, IOSvL2, ASAv, and NX-OS images that you can export and use in EVE-NG.

Juniper: You can download vMX and vQFX trial images from the Juniper website with a free guest account.

Arista/Fortinet/Palo Alto: Most vendors offer "KVM" or "QVM" versions of their software for trial purposes on their support portals. 2. Community and Open Source For non-proprietary nodes, you can download images freely:

Linux: Ubuntu, CentOS, or TinyCore images are readily available. VyOS: A powerful open-source router. PFsense: The go-to for open-source firewalling. How to Install Images in EVE-NG

Once you have downloaded your .qcow2 or .bin files, you can't just drop them anywhere. EVE-NG requires a specific directory structure. Step 1: Upload via WinSCP or FileZilla Connect to your EVE-NG IP address using an SFTP client. Path for QEMU images: /opt/unetlab/addons/qemu/ Path for IOL images: /opt/unetlab/addons/iol/bin/ Step 2: Naming Conventions

EVE-NG is picky. If your folder isn't named correctly, the node will stay grayed out in the menu.

Example: A Palo Alto folder must start with paloalto-. (e.g., paloalto-9.1.0) Example: A Cisco ASAv folder must start with asav-. Step 3: Fix Permissions

This is the step everyone forgets. After uploading an image, you must log into the EVE-NG CLI (via SSH) and run the following command: /opt/unetlab/wrappers/unl_wrapper -a fixpermissions Use code with caution.

Without this, your virtual machines will likely fail to boot or loop indefinitely. Top 3 Must-Have Images for Your Lab

Cisco IOSv & IOSvL2: These are the bread and butter for CCNA/CCNP/CCIE R&S studies. They are much more stable than the old Dynamips images.

FortiGate Next-Generation Firewall: High demand in the job market; the KVM images run flawlessly in EVE-NG.

Arista vEOS: Perfect for learning Data Center switching and automation (Python/Ansible) due to its superb API support. Final Pro-Tip: Hardware Requirements

Before you go on a downloading spree, check your RAM. While a Cisco router might only need 512MB of RAM, a single Palo Alto or NX-OS node can require 4GB to 8GB. Ensure your host machine (or ESXi server) has enough juice to support the images you download.

Building a lab is a journey. Start with the basics, master the fixpermissions command, and you'll have a world-class networking environment at your fingertips.
