Before searching for a download, you need to understand the three categories of images. "All" means having at least one working example from each category.
| Category | Common File Types | Vendors |
| :--- | :--- | :--- |
| Network Device Images | .qcow2, .img | Cisco, Juniper, Arista, Fortinet, VyOS |
| Endpoint/Server Images | .qcow2, .iso | Ubuntu, Windows Server, Kali Linux |
| Utility Images | .qcow2 | VPCS (built-in), Tftpd64, Wireshark |
A "complete" lab doesn't mean every version (e.g., IOS 15.1, 15.2, 15.3). It means having a functional set: at least one router OS, one switch OS, one firewall, one Linux host.
EVE-NG (Emulated Virtual Environment Next Generation) is a powerful network emulator, but it comes with no pre-installed images. You must provide your own. This guide walks you through downloading the most common Cisco, Juniper, Windows, and Linux images, then importing them into EVE-NG.

| Dynamips crashes | Use 64-bit image with idlepc value |
| QEMU hangs at boot | Increase RAM/CPU in node config |
| IOL license error | Add IOL license file to /opt/unetlab/addons/iol/bin/iourc |
