(Note: Some templates like the Cisco Nexus 9000v or older ASA versions may require specific names like sataa.qcow2 . Check the official EVE-NG naming matrix if your node fails to boot). Step 3.4: Fix Permissions (Crucial Step)
EVE-NG will not run images with incorrect file permissions. You must execute the wrapper script every time you add, modify, or move an image file: /opt/unetlab/wrappers/unl_wrapper -a fixpermissions Use code with caution. 5. Troubleshooting Common Image Issues
/opt/unetlab/wrappers/unl_wrapper -a fixpermissions
: This is the most critical step. Log into your EVE-NG CLI via SSH and run: /opt/unetlab/wrappers/unl_wrapper -a fixpermissions 4. Verified Images for 2026 Download Eve-ng Images -UPD-
EVE-NG is a clientless network emulation tool that allows engineers to build and test virtual network labs.
Here is the updated list of official sources. Stop using random Google Drives from Reddit.
You can use PnetLab, which has a built-in store to "pull" images, then transfer those files to your EVE-NG setup. 2. Uploading to EVE-NG (Note: Some templates like the Cisco Nexus 9000v
Before we dive into the download process, it is crucial to understand a legal reality:
EVE-NG (Emulated Virtual Environment - Next Generation) is a powerful network emulation tool. However, out of the box, it is simply a platform; to create labs, you must add (also known as "qcow2" files). These images contain the operating systems of the vendors you want to emulate, such as Cisco IOL, Dynamips, vIOS, Palo Alto, or Fortinet.
EVE-NG categorizes virtual machines and operating systems into three distinct directories based on their underlying virtualization technology. QEMU (KVM) Images /opt/unetlab/addons/qemu/ You must execute the wrapper script every time
Every QEMU image must reside in its own specifically named folder inside /opt/unetlab/addons/qemu/ .
Create a directory for the image using vendor and image name:
The tag indicates that the image sources have been refreshed to support QEMU 6.0+ and kernel 5.x.
