Introduction to nexus9300v64.10.2.5.M.qcow2 Software

The ​​nexus9300v64.10.2.5.M.qcow2​​ file is Cisco’s virtualized Nexus 9300v switch image running NX-OS 10.2(5)M, released on March 15, 2024. Designed for network prototyping and testing in KVM/QEMU environments, this virtual appliance emulates the hardware functionality of physical Nexus 9000 series switches, enabling administrators to validate SDN architectures, test policy configurations, and simulate multi-tier data center topologies without physical hardware.

This version specifically targets organizations transitioning to ACI (Application Centric Infrastructure) fabrics, providing feature parity with physical Nexus 9300 switches up to 64 virtual interfaces. Compatible with Red Hat Virtualization (RHV) 4.4+ and Ubuntu KVM 22.04 LTS, it serves as an essential tool for pre-deployment validation of NX-OS upgrades.
