Are you ready to take your networking labs to the next level? Building a powerful virtual lab in
(Emulated Virtual Environment Next Generation) is a game-changer, but the first hurdle is always getting those device images running.
Since EVE-NG does not provide copyrighted vendor images directly, you’ll need to source and prepare them yourself. Here’s a quick guide to getting started: 1. Sourcing Your Images Official Channels
: Always prefer downloading images from official vendor sites like Cisco Software Central
for VIRL/vIOS images or Palo Alto's support portal for KVM images. Community Collections
: Many network engineers share organized PDF collections or links on platforms like that point to essential ISOs and image packs. 2. Uploading to EVE-NG : Use an SCP/SFTP client like or FileZilla to connect to your EVE-NG server’s IP. Directory Structure : Pay close attention to the Qemu image naming conventions . For example, Cisco IOL images belong in /opt/unetlab/addons/iol/bin/ , while QEMU images go into /opt/unetlab/addons/qemu/ 3. The Magic Command: Fix Permissions The most common mistake! After uploading any image, you
run this command from the EVE-NG CLI to ensure the system can access the files: /opt/unetlab/wrappers/unl_wrapper -a fixpermissions Helpful Resources: How to load images - - EVE-NG
eve-img download cisco-iosv-15.6.2T --verify
eve-img list-remote --filter vendor=cisco
eve-img install ./local-image.tar.gz
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).
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. Download-- Eve-ng Images
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.
Ultimate Guide: Download and Install EVE-NG Images The Emulated Virtual Environment Next Generation (EVE-NG) is the industry-leading tool for network professionals to build, test, and troubleshoot multi-vendor networks. To use it effectively, you must understand how to download EVE-NG images and properly integrate them into your platform. 1. Where to Legally Download EVE-NG Images
It is a common misconception that EVE-NG provides network vendor images. Due to copyright and licensing, EVE-NG does not host or distribute images for Cisco, Juniper, Fortinet, or other vendors. To get images legally, you should:
Manufacturer Portals: Download from official sites like Cisco Software Central if you have an active support contract.
Cisco Modeling Labs (CML): The most common legal way to obtain Cisco images (IOSv, ASAv, etc.) is by purchasing Cisco Modeling Labs, which includes a reference platform ISO full of authorized images.
Trial Licenses: Vendors like Fortinet, Palo Alto, and F5 often offer "KVM" or "QCOW2" trial images for lab use. 2. Supported Image Types
EVE-NG supports three primary image formats, each requiring a specific storage path on your EVE-NG server: EVE-NG LAB Training Course With Configuration for Beginners
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). Are you ready to take your networking labs to the next level
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 eve-img download cisco-iosv-15
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.
