If you are studying for Cisco CCNA, CCNP, or CCIE—or working with Juniper, Palo Alto, or F5—you have likely heard of EVE-NG (Emulated Virtual Environment – Next Generation). It is the gold standard for network simulation. However, the software itself is just an empty shell. The magic happens when you add images (operating systems for routers, firewalls, and servers).
This guide provides a fully updated (2024-2026) walkthrough on how to legally acquire, download, and import these images into EVE-NG Community or Professional Edition.
Even with the latest EVE-NG version (5.0+), updated images can fail. Here are the top fixes:
| Problem | Solution |
|---------|----------|
| "QEMU exited with error code 1" | Re-run fixpermissions. Check if the image is corrupted (run qemu-img info image.qcow2). |
| Cisco IOSvL2 won’t boot | Set "Console" to telnet, not VNC. Add "console": "telnet" in the node definition. |
| Image not showing in dropdown | Did you name the folder with dashes/hyphens? Use Cisco-IOSv-15.9 not Cisco IOSv 15.9 (no spaces). |
| High CPU usage (100%) | EVE-NG default CPU limit is 1 core. Under node config, set "CPU limit percentage" to 40 for IOSv. |
| New ARM-based EVE-NG (Apple Silicon) | You need ARM64 versions of images. Ubuntu 24.04 ARM, vSRX ARM, but NOT Cisco IOSv (x86 only). Use qemu-system-aarch64 emulation. |
If you want a stable lab without chasing "dead links," here is the current compatibility matrix for EVE-NG v6.0+:
| Vendor | Device Name | File Format | Working Version (2026) | | :--- | :--- | :--- | :--- | | Cisco | IOSv | QEMU | 15.9(3) M3 | | Cisco | CSR1000v | QEMU | 17.12.1a | | Cisco | Nexus 9000v | QEMU | 10.4(2) | | Arista | vEOS-Lab | QEMU | 4.31.2F | | Juniper | vSRX 3.0 | QEMU | 24.2 | | Palo Alto | PA-VM | QEMU | 11.1.4 | | Fortinet | FortiGate-v04 | QEMU | 7.6.0 | | Huawei | AR1000v | QEMU | V300R023 |

Do not use or distribute unlicensed images or links to pirated content.
When users search for this, they are usually looking for a shortcut. Setting up images in EVE-NG natively requires obtaining the original ISOs from vendors and converting them manually—a process that can be time-consuming.

Advanced Serial Port Terminal is a versatile application that provides serial terminal software with which to address many communication challenges. It should be in every serial developer’s software toolbox for sending data over serial connections to facilitate hardware and software testing and debugging.
Some specific uses of this serial terminal solution are:
It is apparent that Serial Port Terminal is a great free alternative for users employing HyperTerminal on Win 7, 10, or other versions of Windows. It offers more functionality than HyperTerminal and is an important tool for serial software and hardware development. It is a synthesis of a serial terminal and COM port sniffer in a single application.
