This guide explains how to install and configure the Cisco Nexus 9000v (NX-OSv 9000) virtual switch using the specific image file nxosv.7.0.3.I7.4.qcow2. This version is commonly used in network emulation environments like EVE-NG or GNS3 to simulate high-performance data center environments. 1. Image Preparation and Naming

If you are looking for information on how to deploy or use this specific image, you should refer to documentation regarding virtual lab environments and Cisco's official product guides: Technical Documentation & Implementation EVE-NG Deployment nxosv9k703i74qcow2

3. Important warnings (Legal & technical)

  • Proprietary & copyrighted – This file is not open source or freeware. It is copyrighted by Cisco Systems. You need a valid support contract, Cisco account with entitlement, or a CML/VIRL subscription to legally obtain and use it.
  • Resource heavy – NX-OS virtual images are notorious for high RAM and CPU usage. Expect this image to require 4–8 GB of RAM and significant disk I/O just to boot one instance.
  • Not for production – These virtual images are for lab/emulation only, not for running real network traffic in production.

Part 3: What If You Already Have nxosv9k703i74qcow2?

Assume you found this file on a shared drive, torrent, or lab dump. Here’s what to do: This guide explains how to install and configure

  • The Feature: This image allows you to simulate a full Software-Defined Network (SDN) fabric without physical hardware.
  • Technical Detail: It supports "Spine-Leaf" topology simulation. You can deploy multiple instances of this image and configure them as VTEPs (VXLAN Tunnel Endpoints). It supports BGP Address Families (l2vpn evpn) to exchange MAC/IP information, allowing a laptop to simulate a multi-tenant data center fabric.

1. Key Capability: VXLAN BGP EVPN Fabric Simulation

The 7.0(3)I7 train is historically significant because it introduced a mature, stable implementation of VXLAN BGP EVPN for the virtual platform. Proprietary & copyrighted – This file is not

Step 2: Convert QCOW2 toVirtualBox Format

  1. Convert the QCOW2 file to VirtualBox's compatible format (.vmdk) using qemu-img: 
    qemu-img convert -f qcow2 nxosv9k703i74qcow2 -O vmdk nxosv9k703i74.vmdk
  2. Create a new VirtualBox VM and attach this .vmdk file.
  • Release date: ~2017–2018
  • For Nexus 9000 virtual (vN9K)
  • I7 train is known for features like VXLAN, EVPN, and enhanced routing.
