What (like vPC, routing protocols, or automation) are you hoping to test?
Many network engineers find pre-configured lab images shared within the EVE-NG or GNS3 communities. When sourcing files from third-party links or community forums, always verify the file integrity by checking the MD5 or SHA256 checksums against official Cisco documentation to ensure the file hasn't been altered or corrupted. Importing the Image into Network Emulators
Access your EVE-NG server via SSH or an SFTP client (like FileZilla). Navigate to the QEMU directory: /opt/unetlab/addons/qemu/
The node may power on for a few seconds and then abruptly turn itself off.
At this point, you'll be dropped to the NX-OS command-line interface (CLI).
Alternatively, you can SSH directly:
Rename your downloaded file to match EVE-NG's strict naming conventions. The standard filename required inside the folder is virtioa.qcow2 . 2. Create the Directory via SSH
The 7.0.3.i7.4 release is part of the "I" train, which is specifically optimized for virtual environments. Key features often utilized in this version include:
Searching for "pieces" of software on third-party file-sharing sites is risky: Images can be modified to include backdoors.
cd /opt/unetlab/addons/qemu/nxosv9k-7.0.3.I7.4/ mv nxosv-final.7.0.3.I7.4.qcow2 sataa.qcow2 /opt/unetlab/wrappers/unl_wrapper -a fixpermissions
The is a virtual machine disk image (QEMU Copy On Write) that runs the Cisco Nexus Operating System (NX-OS). It is designed to emulate the control plane of Nexus 9000-series switches. Version: 7.0(3)I7(4) Format: QCOW2 (compatible with KVM, EVE-NG, GNS3, QEMU)
| Resource | Minimum Requirement | Recommended Requirement | Notes | | :--- | :--- | :--- | :--- | | | 4 vCPUs | 8+ vCPUs | Requires 2-4 physical CPU cores, not just threads. You must enable hardware virtualization (Intel VT-x/EPT or AMD-V/RVI) for KVM. | | RAM | 10 GB | 16+ GB (per node) | While the base VM needs 5GB, the node itself requires at least 8GB allocated. Many sources state a minimum of 10GB for bootup. For a stable lab, 16GB or more per node is recommended. | | Storage | 20 GB | 50 GB+ | For the base image and configuration files. | | Hypervisor | KVM/QEMU (2.2.0+) | KVM/QEMU (2.10.0+) | QEMU 2.2.0 is the minimum, but Ubuntu 16.04.3 LTS often uses QEMU 2.10.0-rc3 for better performance. |
If you are looking to run this in a specific environment, I can provide more details if you let me know: Are you using , GNS3 , or QEMU directly ?
