EVE-NG (Emulated Virtual Environment - Next Generation) is a network emulation platform similar to GNS3 and Cisco Packet Tracer. However, the software itself is just a shell; the "images" are the operating systems (Cisco IOS, Palo Alto PAN-OS, Juniper JunOS, Fortinet FortiOS, etc.) that actually run inside it.
Here is a breakdown of the pros, cons, and critical warnings regarding the downloading and usage of these images.
EVE-NG images are virtual disk images or install packages for network OSes (IOS, IOS-XE, IOS-XR, NX-OS, JunOS, PAN-OS, Cisco ASA/FTD, FortiGate, VyOS, pfSense, etc.) and appliances (firewalls, load balancers, servers) converted or packaged to run inside the EVE-NG hypervisor. They let you emulate real network devices for testing, certification labs, training, and development.
Here is my curated list of images to make your lab useful:
| Device | Image Name | Use Case |
| :--- | :--- | :--- |
| Cisco Router | vios-adventerprisek9-m-16.09.01.qcow2 | Routing, BGP, MPLS |
| Cisco Switch | vios_l2-adventerprisek9-m-15.2.qcow2 | Spanning Tree, VLANs, Etherchannel |
| Linux Host | TinyCore-latest.qcow2 | Tiny 50MB Linux for ping/traceroute |
| FortiGate | fortinet-FGT-v7.4.qcow2 | Firewall policies, SSL VPN |
| Windows Server | Windows-Server-2019.qcow2 | DHCP, DNS, Active Directory (requires KVM) |
If you downloaded an image from a shady "Download EVE-NG Images" site and it doesn't work, here is the diagnosis: Download-- Eve-ng Images
Problem 1: "Could not open disk image"
Problem 2: QEMU process killed (High CPU)
Problem 3: Serial console is garbage/text scrambled
Problem 4: IOL won't boot (Error: 8)
The process of acquiring and "fixing" images is often the biggest hurdle for new users.
/opt/unetlab/addons/), and often require fixing permissions using a specific script (/opt/unetlab/wrappers/unl_wrapper -a fixpermissions). For beginners, this Linux command-line work is daunting compared to the "next-next-finish" installation of other simulators.EVE-NG does not provide proprietary firmware (e.g., Cisco IOS, Arista vEOS, Juniper vJunos-switch). You must legally own these images, typically via a valid support contract with the vendor, or use free/open-source alternatives (like Linux or VyOS). Verdict: Essential for Functionality, but legally complex
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.
