Introduction to nexus9300v64-lite.10.4.3.F.qcow2 Software
This lightweight QCOW2 virtual machine image provides NX-OS 10.4(3)F functionality for Cisco Nexus 9300v switches in KVM environments. Designed for resource-constrained lab testing and network prototyping, it emulates the behavior of physical Nexus 9300-FX3 series switches with 32 virtual data ports and 1 management interface while consuming 40% less memory than standard builds.
The “lite” designation indicates optimized resource allocation for educational and development environments, maintaining full NX-OS CLI parity with hardware counterparts. Cisco’s release notes highlight its role in validating VXLAN EVPN configurations and SD-WAN integration workflows.
Key Features and Improvements
-
Resource Optimization
- Reduced memory footprint to 6GB baseline (vs 10GB in standard builds)
- Streamlined packet processing buffers for lab-scale traffic simulations
-
Security Enhancements
- Integrated OpenSSL 3.2.3 security patches (CSCwz65993 backport)
- Added MACsec 256-bit encryption support for virtual links
-
Protocol Support
- BGP EVPN Type-2/Type-5 route capacity increased to 250K prefixes
- VXLAN-GPE encapsulation latency reduced by 18%
-
Management Features
- Enhanced NETCONF/YANG model coverage for virtual chassis configurations
- Added Python 3.11 runtime support for automation scripts
Compatibility and Requirements
| Virtualization Platform | Minimum RAM | Disk Space | Virtual CPUs |
|---|---|---|---|
| KVM/QEMU 6.2+ | 8GB | 18GB | 2 |
| Proxmox VE 8.0+ | 8GB | 20GB | 2 |
Critical Notes:
- Requires CPU with AES-NI instruction set for encrypted traffic simulations
- Incompatible with Libvirt 7.0+ managed networks using Open vSwitch 2.15
- QEMU emulator must use “qemu64-v2” CPU type for stability

Introduction to nexus9500v64.10.3.3.F.qcow2 Software
This QCOW2 format virtual appliance implements NX-OS 10.3(3)F for modular Nexus 9500v switches in KVM environments. Supporting up to 8 virtual line cards and 200 interfaces, it replicates the chassis-based architecture of physical Nexus 9516 platforms for large-scale network simulations.
The 10.3(3)F release focuses on multi-tenant cloud environments, featuring enhanced VRF-lite support and QoS policy templates. Official documentation confirms backward compatibility with NX-API versions 2.4-3.1 for legacy automation workflows.
Key Features and Architectural Improvements
-
Scalability Enhancements
- Virtual line card density increased to 8 modules per chassis
- Shared buffer pool expanded to 48MB for burst traffic handling
-
Fabric Security
- Implemented VXLAN EVPN ingress replication optimizations
- Added flow telemetry monitoring for microsegmentation audits
-
Performance Upgrades
- OSPFv3 convergence time reduced to <1.2 seconds
- PIM-SSM join latency improved by 25% under 500-group loads
-
Operational Efficiency
- Extended Ansible collection coverage for fabric provisioning
- RESTCONF API response time reduced by 40%
Compatibility Matrix
| Host Environment | Recommended Configuration | Storage Allocation |
|---|---|---|
| Red Hat KVM 3.10+ | 16GB RAM + 6 vCPUs | 32GB thin-provisioned |
| Ubuntu 22.04 LTS | 24GB RAM + 4 vCPUs | 36GB raw format |
Upgrade Restrictions:
- Requires existing NX-OS 10.2(1) or later baseline configuration
- Incompatible with legacy Python 2.7 automation frameworks
- Control plane redundancy requires separate VM instances
