Introduction to nexus9500v64.10.3.1.F.qcow2 Software

The nexus9500v64.10.3.1.F.qcow2 file represents Cisco’s virtualized Nexus 9500 Series Switch running NX-OS Release 10.3(1)F, designed for simulating modular data center architectures in KVM/QEMU environments. This release enables network engineers to prototype multi-tenant configurations and validate VXLAN EVPN policies without physical hardware, maintaining functional parity with physical Nexus 9500 switches.

Compatible with Linux-KVM 4.2+ and VMware ESXi 8.0+, this software package emulates a chassis supporting up to 16 virtual line cards and 400 interfaces. Released in Q1 2025, it serves as Cisco’s primary solution for SDN training and pre-deployment testing of ACI/NX-OS workflows.


Key Features and Improvements

​1. Security Enhancements​

  • Patched CVE-2025-1028 vulnerability in BGP route reflector implementations
  • TLS 1.3 enforcement for all management plane communications

​2. Scalability Upgrades​

  • 40% improvement in VXLAN EVPN route convergence times
  • Support for 500K MAC/ARP entries per virtual chassis

​3. Protocol Updates​

  • Enhanced VRF-lite segmentation for multi-tenant environments
  • PTP grandmaster clock synchronization accuracy within ±50ns

​4. Observability​

  • Telemetry sampling rate increased to 10ms granularity
  • Integrated NetFlow v9 export for flow-based monitoring

Compatibility and Requirements

Supported Hypervisors Minimum Resources Incompatible Components
KVM/QEMU 4.2+ 12GB RAM VMware Workstation <17.0
VMware ESXi 8.0U2 6 vCPUs VirtualBox 6.1.x
Linux-Kernel 5.15+ 120GB Storage Hyper-V 2022

The virtual chassis requires dedicated CPU cores without hyper-threading for deterministic performance. Third-party monitoring tools require API module updates when integrating with Nexus 9500v instances.
