Introduction to nexus9500v64.10.2.5.M.qcow2 Software

The ​​nexus9500v64.10.2.5.M.qcow2​​ is Cisco’s enterprise-grade virtual switch image emulating the Nexus 9500 Series modular switches, released on February 15, 2025. Designed for SDN architecture validation and large-scale data center simulations, this virtual appliance provides full feature parity with physical Nexus 9500 switches up to 64 virtual interfaces per line card.

Compatible with VMware ESXi 8.0U3+ and KVM/QEMU 6.5+, it enables network engineers to prototype multi-tier ACI fabrics, test QoS policies, and validate VXLAN configurations without physical hardware. The “lite” designation indicates optimized resource consumption for lab environments while retaining production-grade NX-OS capabilities.
