Solution: Increase disk space. The .qcow2 file expands to 8GB+ during first boot. Ensure your host has free disk.
If you search for nxosv9k-7.0.3.i7.4.qcow2 free download on Google or torrent sites, you will find dozens of links. However, most fall into three categories:
Verdict: ⭐⭐⭐⭐ (4/5) – Great for learning, frustrating for production expectations.
Let’s be honest: you’re not downloading this because Cisco sent you a kind email. You’re here because you want to learn VXLAN, EVPN, or Cisco ACI-like CLI without spending $10k on real Nexus hardware. And for that? This image is a hidden gem.
The short answer is yes, but with caveats.
Cisco does not provide the NXOSv9k image for free on its public download portal (Cisco.com) without a valid service contract. However, because this specific version (7.0.3.I7.4) is older and widely used for learning, several legitimate channels exist:
Older NX-OS versions did not support MPLS. Release 7.0(3)I7(4) does. Use it to learn Segment Routing or LDP-based MPLS.
When looking for a nxosv9k-7.0.3.i7.4.qcow2 image for your Nexus 9000 series switch, prioritize legal and safe acquisition practices. Cisco's official channels are the best place to obtain software images. Always consult Cisco's documentation and support resources for specific installation and upgrade instructions to ensure a smooth process.
The Cisco NX-OSv 9000 (NX-OSv 9K) image nxosv9k-7.0.3.i7.4.qcow2 is commonly used in virtual lab environments like EVE-NG and GNS3. Important Note on Downloads
Official images must be obtained directly from the Cisco Software Central portal. While third-party links may exist, they are often unauthorized or potentially modified; for a stable and secure lab, always use the official CML (Cisco Modeling Labs) resources.

Once you have the image, follow these steps to integrate it into your EVE-NG server:
Prepare the Directory:Create a folder for the image on your EVE-NG server using the CLI:mkdir -p /opt/unetlab/addons/qemu/nxosv9k-7.0.3.I7.4/
Upload the Image:Use an SCP client (like WinSCP or FileZilla) to upload the .qcow2 file to the directory created above.
Rename the File:EVE-NG requires a specific filename to recognize the disk. Navigate to the folder and rename it:cd /opt/unetlab/addons/qemu/nxosv9k-7.0.3.I7.4/mv nxosv9k-7.0.3.i7.4.qcow2 sataa.qcow2
Fix Permissions:Run the standard EVE-NG utility to ensure the system can access the new files:/opt/unetlab/wrappers/unl_wrapper -a fixpermissions Initial Configuration Steps
When you first boot the node in your lab topology, follow these prompts:
POAP: When asked "Abort Auto Provisioning and continue with normal setup?", type yes.
Secure Password: When asked to enforce secure password standards, you can select no for lab convenience.
Admin Setup: Create a password for the admin user (e.g., admin). Solution: Increase disk space
Basic Config Dialog: When asked if you want to enter the basic configuration dialog, type no to go straight to the CLI. Accessing the CLI
Default Login: Use the credentials created during setup (e.g., admin / admin).
Enter Configuration: Use configure terminal (or conf t) to start modifying settings.
The nxosv9k-7.0.3.i7.4.qcow2 file is a virtual disk image for the Cisco NX-OSv 9000, a virtualized version of the Cisco Nexus 9000 Series switch operating system. This specific version is widely used by network engineers and students for lab simulations in environments like EVE-NG and GNS3. How to Download and Access
For a secure and legal experience, users should obtain software directly from official channels:
Official Cisco Portal: The primary source for all Nexus software is the Cisco Software Download page. Access typically requires a valid Cisco Connection Online (CCO) account and an active service contract.
Cisco Modeling Labs (CML): The NX-OSv 9000 image is often included as part of the Cisco Modeling Labs subscription, providing a legitimate path for personal study and testing. Hardware & System Requirements
The NX-OSv 9000 is a "heavy" node that requires significant resources to run smoothly in a virtual environment:
RAM: A minimum of 8 GB is recommended for stable performance, though it may boot with as little as 4–6 GB with frequent memory warnings. If you search for nxosv9k-7
CPU: Requires at least 2 Physical CPU Cores (not just threads).
Storage: Approximately 750 MB to 2 GB depending on the specific release and image format. Installation Highlights
When setting up nxosv9k-7.0.3.i7.4.qcow2 in simulators like EVE-NG, follow these critical steps:
Naming Convention: Create a folder named exactly nxosv9k-7.0.3.I7.4 in the EVE-NG QEMU directory.
File Renaming: The .qcow2 file must be renamed to sata.qcow2 for the simulator to recognize it correctly.
Permissions: Run the /opt/unetlab/wrappers/unl_wrapper -a fixpermissions command on your EVE-NG server after uploading the file to ensure the system can access the image.
Initial Boot: On the first boot, abort "Auto Provisioning" and choose "no" for the basic configuration dialog to manually set up your switch. Key Features of NX-OSv 9000
Network Simulation: Validates configuration changes on a simulated network before production deployment.
Programmability: Supports modern DevOps models, including NX-API and automation tool testing.
Control Plane Emulation: Shares the same software image as Nexus hardware, effectively simulating control plane aspects without requiring physical chassis. Cisco Nexus 9000v switch - - EVE-NG
