Once you have a "full pack" of working images, keep a backup of the /opt/unetlab/addons/qemu/ directory.
run the following command via the EVE-NG CLI to ensure the system can access the new files [11]: /opt/unetlab/wrappers/unl_wrapper -a fixpermissions Use code with caution. Copied to clipboard 3. Managing Different Vendors
Once you have the image files, follow these general steps to add them to EVE-NG: Prepare the Image : Ensure the image is in a supported format, such as for QEMU or for Cisco IOL/Dynamips [11, 13]. Upload to EVE-NG : Use an SCP client like
This is a legacy emulator used exclusively for older Cisco IOS images (such as Cisco 7200 routers). It is rarely used in modern labs but remains lightweight.
The process of populating an EVE-NG server is often where users face the steepest learning curve. Unlike consumer virtualization software, EVE-NG requires a specific directory structure and naming convention for images to be recognized by the GUI. For example, a QEMU image must reside within a folder prefixed with the device type, such as "vtios-" or "asav-", and the disk file must be named "virtioa.qcow2". This rigid architecture ensures that the underlying Linux kernel correctly maps hardware acceleration to the virtual instance. Furthermore, after any image is manually uploaded via SFTP, the user must execute a "fixpermissions" command to ensure the web interface can properly launch the node. Download All Eve-ng Images
Enable virtualization in BIOS and ensure your EVE-NG is bare-metal or VMware with nested virtualization enabled.
EVE-NG does provide copyrighted vendor images for download directly. To use the platform effectively, you must acquire images from official vendors, use a subscription service like Cisco Modeling Labs (CML), or explore community-provided resources at your own risk. Core Methods to Acquire Images
Create a free guest account on Arista’s website to download vEOS (Virtual Extensible Operating System) ABR images.
Example for Cisco IOSv: Folder must start with viros- , and the disk file must be named virtioa.qcow2 . Once you have a "full pack" of working
Before creating folders, visit the official online. Every vendor has a mandatory folder prefix and hardcoded virtual disk filename.
This is the most common format. Modern network operating systems (like Cisco IOS-XE, Arista EOS, and Juniper JunOS) run as virtual machines via the QEMU emulator.
Downloading and setting up your EVE-NG image library requires patience and attention to detail. By sourcing images legally through vendor portals, adhering strictly to the EVE-NG naming conventions, and remembering to run the fix permissions script, you can build an enterprise-grade testing environment right on your computer.
Example for Palo Alto FW: The folder must start with paloalto- . Inside the folder, the file must be renamed to virtioa.qcow2 . Managing Different Vendors Once you have the image
EVE-NG (Emulated Virtual Environment - Next Generation) is the premier tool for network engineers, architects, and cybersecurity professionals to build sophisticated, multi-vendor labs. However, an EVE-NG installation is merely a shell—an empty laboratory—without the .

Depending on your image type, move the files to the following paths: /opt/unetlab/addons/qemu/ For IOL Images: /opt/unetlab/addons/iol/bin/ For Dynamips Images: /opt/unetlab/addons/dynamips/ Step 3: Use the Strict Naming Convention
