Nexus9300v.9.3.9.qcow2 Extra Quality Jun 2026

ESXi does not read QCOW2 natively.

The file extension ".qcow2" is not merely a container; it is a statement of compatibility with the modern data center stack. The QEMU Copy-On-Write version 2 format is the de facto standard for disk images in open-source virtualization, specifically with the Kernel-based Virtual Machine (KVM) and Quick Emulator (QEMU) hypervisors.

EVE-NG requires strict naming conventions for its qemu directories to automatically detect the node type. Connect to your EVE-NG server via SSH.

To utilize this image in a virtual lab environment, follow these general steps based on Karneliuk's infrastructure guide and EVE-NG documentation: : nexus9300v.9.3.9.qcow2

Has anyone successfully integrated this version with Cisco's official documentation for automation workflows yet? Let's discuss! Next Step: Cisco Nexus 9000/3000 Virtual Switch - GNS3

The "Nexus9300v" component of the filename refers to the virtualized version of Cisco’s Nexus 9300 fixed-configuration switches. Unlike its physical counterparts, the 9300v is a software image designed to run as a Virtual Machine (VM) on generic x86 hardware or within cloud environments. This virtualization offers network engineers and DevOps practitioners a sandbox environment that mirrors the behavior of production hardware with high fidelity.

The virtual image maps QEMU network interfaces to physical Nexus Ethernet ports: ESXi does not read QCOW2 natively

For bare-metal Linux servers or automated CI/CD pipelines, launch the image directly via the CLI:

: Minimum of 4GB RAM for basic bootup, though 8GB to 12GB is recommended for full feature support (like BGP EVPN).

Remember, the default username is admin , but you'll need to set a strong password on the first boot. EVE-NG requires strict naming conventions for its qemu

This article unpacks everything you need to know about the nexus9300v.9.3.9.qcow2 image—from its architectural limitations to advanced deployment scripts.

Verify that Intel VT-x or AMD-V is enabled in your host system's BIOS. In EVE-NG or GNS3, ensure that the QEMU options include the -enable-kvm flag. 3. Interfaces Do Not Pass Traffic

Ensure that Intel VT-x/AMD-V and nested virtualization are enabled in your underlying bare-metal hypervisor (ESXi, Proxmox, or Workstation) so EVE-NG can pass hardware acceleration through to the QEMU container.

The Cisco Nexus 9300v is a virtual switch platform designed to replicate the features and performance of physical Cisco Nexus 9000 series switches. It runs the Cisco NX-OS operating system and allows engineers to design, test, and validate network topologies in a risk-free virtual environment.
