SSH into your EVE-NG server (Ubuntu bare-metal or VM). The path matters strictly:
cd /opt/unetlab/addons/qemu/
Create a folder named exactly as the node type requires. For Cisco IOSv:
mkdir iosv-15.6.2
Upload the .qcow2 file into this directory and rename it to virtioa.qcow2 (or hda.qcow2 depending on the image; check EVE-NG cookbook): eve-ng qemu images download
scp your-local-image.qcow2 root@your-eve-ip:/opt/unetlab/addons/qemu/iosv-15.6.2/virtioa.qcow2
EVE-NG supports multiple virtualization technologies, but QEMU is the most versatile. It emulates the hardware architecture (x86_64, ARM, etc.), allowing users to run unmodified operating systems.
Why QEMU Images?
You can create your own QEMU image from an ISO:
After downloading the ISO, install it manually in EVE-NG (covered below). SSH into your EVE-NG server (Ubuntu bare-metal or VM)
Downloading is just the beginning. To make QEMU nodes run smoothly:
