The Cisco Nexus 9300v is a virtual switch appliance that emulates the hardware Nexus 9300 platform. The image nexus9300v.9.3.9.qcow2 (based on NX-OS version 9.3(9)) is the latest iteration in the 9.3.x train, designed for virtualized environments (KVM, VMware ESXi, OpenStack) and containerized labs (EVE-NG, GNS3, Cisco Modeling Labs – CML).
operating system, Cisco has moved the "physical" lab into the cloud, allowing for high-fidelity simulations without the massive capital expenditure of hardware. The Evolution of the Virtual Lab

Cisco Nexus 9300v 9.3(9) qcow2 is a virtual network switch image designed for data center simulation and lab testing. This version is part of the NX-OS 9.3(x) release train, providing a stable platform for testing complex network topologies like VXLAN BGP EVPN without physical hardware. Key Overview & Features The Nexus 9300v functions as a virtual non-modular switch. Virtual Line Card
| Area | Limitation | |------|-------------| | Throughput | Limited by hypervisor CPU (~100–200 Mbps) | | Port density | 48 x 10G + 4 x 40G logical interfaces | | VXLAN hardware offload | None – simulated via CPU | | MAC address table | Reduced scale | | No PTP, no PoE, no UADP ASIC simulation | Default login: admin / (no password or "admin")
Cisco has already hinted that the 9.3.x train is in maintenance mode. The next major release (10.x) will focus on containerized NX-OS (cNexus) and DPU offloading. However, for the next 18-24 months, the nexus9300v939qcow2 new will remain the de facto standard for virtual data center labs.
