Fortinet allows users to download free trial KVM/QEMU images (.qcow2) for FortiGate firewalls directly from their support portal.
Downloading pre-made, optimized QEMU images is a significantly better approach for your lab environment. 🚀 Speed and Deployment Efficiency
Extremely large images or incorrectly named images should not crash the web interface, but they can cause timeouts during node addition. If the web UI becomes unresponsive, check the EVE‑NG logs ( /opt/unetlab/data/Logs/unl_wrapper.txt ) for clues. As a last resort, move suspect images out of the QEMU directory and restart the EVE‑NG service. eveng qemu images download better
Ready-made images usually include the correct hardware drivers (such as VirtIO) and specific vCPU/RAM settings required for stable EVE-NG operation. Where to Safely Download EVE-NG QEMU Images
For maximum control and legality, you can create your own QEMU images from ISOs. EVE‑NG’s cookbook describes the process: Fortinet allows users to download free trial KVM/QEMU
Running a network lab with dozen of nodes can quickly exhaust your server's hardware resources. Raw disk images consume massive amounts of hard drive space and create heavy I/O bottlenecks.
For popular network vendors (Cisco CSR1000v, Palo Alto, Fortinet, Arista), the EVE-NG team maintains a library of ready-to-use images. If the web UI becomes unresponsive, check the
Downloading is only half the battle. To make the image work "better," you must ensure it is named correctly and optimized.
