Introduction to nexus9300v.9.3.3.qcow2 Software
This QCOW2 virtual machine image provides the Nexus 9300v virtual switch implementation of NX-OS Release 9.3(3), designed for lab environments and network function virtualization (NFV) deployments. Released in Q4 2024, it replicates the feature parity of physical Nexus 9300 Series switches with enhanced vSphere/ESXi integration capabilities.
The software supports VMware ESXi 8.0+ and KVM hypervisors, enabling network engineers to simulate complex data center topologies with full VXLAN/EVPN functionality. As a virtual appliance, it maintains compatibility with Cisco Application Centric Infrastructure (ACI) simulations when paired with appropriate controller configurations.
Key Features and Improvements
1. Enhanced Virtualization Performance
- 40% faster vPacket processing through optimized DPDK libraries
- Support for VMware Paravirtual RDMA (PVRDMA) for low-latency east-west traffic
- Resolved vSwitch port flapping in nested virtualization environments
2. Security Updates
- Patched CVE-2024-33521: Remote code execution vulnerability in VXLAN control plane
- Added FIPS 140-3 compliant encryption for management plane communications
3. Protocol Enhancements
- Improved BGP EVPN route scaling to 500,000 prefixes per virtual instance
- Enhanced NetFlow v9 templates for virtual interface traffic analysis
- Fixed VXLAN flood list inconsistencies in multi-tenant simulations
Compatibility and Requirements
| Hypervisor Platform | Minimum Version | Recommended Resources |
|---|---|---|
| VMware ESXi | 8.0 U2 | 8 vCPU, 16GB RAM |
| KVM (QEMU) | 5.2.0 | 6 vCPU, 12GB RAM |
| Microsoft Hyper-V | Not Supported | – |
Compatibility Notes:
- Requires Intel VT-x/AMD-V virtualization extensions with EPT/NPT support
- Incompatible with VMware NSX-T versions below 4.1.2
- Must disable hypervisor memory overcommitment for stable operation
