I can’t provide or link to copies of proprietary/paid software images (like Cisco NX‑OS QCOW2 files). If you have a valid support contract or license, download it from Cisco’s official software repository (Cisco.com) using your account; if you don’t, you’ll need to obtain proper licensing or use vendor-provided evaluation images.
If you want, I can:
Downloading Cisco NX-OSv images usually requires a valid Cisco service contract. Publicly shared "pieces" or unofficial download links for these files often carry security risks or violate licensing terms. 🛡️ Official Download Method
The safest and only official way to get this image is through the Cisco Software Central portal. Visit the Cisco Software Download page. Search for NX-OSv or Nexus 9000v. Log in with a Cisco Connection Online (CCO) account.
You must have an active Cisco Modeling Labs (CML) subscription or a service contract associated with your account to download .qcow2 files. 💡 Alternative for Lab Testing
If you are looking for this image for learning or lab environments (like GNS3 or EVE-NG), consider these options:
Cisco Modeling Labs (CML): This is the official replacement for VIRL. It provides legal access to NX-OSv, IOSv, and other images for a yearly subscription.
Cisco DevNet Sandbox: You can reserve free lab time on Cisco DevNet to use Nexus switches in a cloud environment without downloading any files. ⚠️ A Note on Unofficial Links
Searching for "pieces" of software on third-party file-sharing sites is risky: Malware: Images can be modified to include backdoors.
Corruption: Multi-part "pieces" often fail during reassembly.

The nxosv-final.7.0.3.i7.4.qcow2 image is a virtualized version of the Cisco Nexus 9000 series switch, often used in lab environments like EVE-NG or GNS3. One of its most interesting and powerful features is the Guest Shell. The Feature: Guest Shell (NX-OS Release 7.0(3)I)
The Guest Shell is a secure, isolated Linux container (LXC) that runs alongside the NX-OS software. It allows you to run standard Linux applications and scripts directly on the switch without affecting the core network operating system.
Python Integration: It comes pre-installed with Python, allowing you to write scripts that interact directly with the switch's hardware and state using the NX-API.
System Access: From within the Guest Shell, you have access to the switch's bootflash and networking stack, making it an ideal tool for on-box automation and custom monitoring.
Resource Efficiency: In this specific release branch, the Guest Shell is lightweight, typically occupying only about 35 MB of RAM and 350 MB of bootflash when enabled.
Package Management: It includes a package manager (like yum or dnf depending on the underlying CentOS/Fedora base), so you can install additional Linux utilities for troubleshooting or data collection. Implementation Note for Lab Users

This version introduced several critical capabilities for virtual data center simulation: Cisco Nexus 9000v switch - - EVE-NG
Finding the right Nexus 9000v image is a critical step for network engineers looking to simulate high-end Cisco switching environments in labs like GNS3, EVE-NG, or VMware. Specifically, the Nxosv-final.7.0.3.i7.4.qcow2 file is a popular stable release used to study VXLAN, OSPF, and BGP without the need for expensive physical hardware.
This guide covers what this specific image is, how to set it up, and the best practices for running it in your virtual lab. What is the Nxosv-final.7.0.3.i7.4.qcow2 Image?
The NX-OSv (Nexus 9000v) is a virtualized version of Cisco’s data center operating system. The filename Nxosv-final.7.0.3.i7.4.qcow2 tells us several things:
7.0.3.i7.4: This is the software version. It is part of the "I" train, which is specifically optimized for the virtual Nexus 9000 platform.
.qcow2: This is the file format (QEMU Copy-On-Write). It is the standard format for Linux-based virtualization and is natively supported by EVE-NG and GNS3. Why Use Version 7.0.3.i7.4?
While newer versions of NX-OSv exist (like the 9.x or 10.x series), version 7.0.3 remains a "sweet spot" for many students and engineers because:
Lower Resource Consumption: It generally requires less RAM (typically 4GB to 8GB) compared to newer versions that may demand 12GB+ per node.
Stability: It supports core VXLAN BGP EVPN features, which are the backbone of modern CCNP and CCIE Data Center studies.
Compatibility: It integrates smoothly with older versions of virtualization software. How to Install Nxosv-final.7.0.3.i7.4.qcow2 1. In EVE-NG
To add this image to EVE-NG, you must follow the strict naming convention required by the platform:
Create the directory: Use SSH to access your EVE-NG server and create a folder named exactly nxosv9k-7.0.3.i7.4 inside /opt/unetlab/addons/qemu/.
Upload the file: Use an FTP client (like WinSCP) to move the .qcow2 file into that folder.
Rename the file: The file must be renamed to virtioa.qcow2 for EVE-NG to recognize it as a bootable disk.
Fix Permissions: Run the command /opt/unetlab/wrappers/unl_wrapper -a fixpermissions. 2. In GNS3 Open GNS3 and go to Edit > Preferences > QEMU VMs. Click New and give it a name (e.g., Cisco NX-OSv 9000). Allocate at least 4096MB (4GB) of RAM and use 1 vCPU.
Select the Nxosv-final.7.0.3.i7.4.qcow2 file as the primary disk image. Set the Console Type to telnet. Important Hardware Requirements
Simulating Nexus switches is resource-intensive. If you plan to build a small leaf-and-spine topology with four switches, ensure your host machine meets these minimums: RAM: At least 32GB (to account for the OS and overhead).
CPU: A processor that supports Intel VT-x or AMD-V virtualization.
SSD: Running these images on a traditional HDD will result in extremely slow boot times (sometimes over 10 minutes). Safety and Licensing Note
The Cisco Nexus 9000v is a proprietary software product. To download this image legally, you should have a valid Cisco Service Contract (Cisco Connection Online - CCO) account. You can download the latest official images directly from the Cisco Software Download portal. Avoid downloading .qcow2 files from third-party "mirror" sites, as these files can be corrupted or contain security risks. Final Thoughts
