qemu-img convert -f qcow2 -O vmdk nxosv9k-7.0.3.i7.4.qcow2 nxosv9k.vmdk Assume you have a Ubuntu 22.04 host with libvirt installed. Step 1: Download the Image Obtain nxosv9k-7.0.3.i7.4.qcow2 from Cisco’s Software Download portal (requires valid SmartNet or CCO login). Path: Products → Switches → Data Center Switches → Nexus 9000 → NX-OS Software → 7.0(3)I7(4) Step 2: Create a Virtual Network (Optional) virsh net-define /etc/libvirt/qemu/networks/lab_net.xml virsh net-start lab_net Step 3: Install libguestfs Tools (for password injection) Nexus 9Kv requires an initial admin password injected via serial console .

In the rapidly evolving landscape of data center networking, the ability to test, validate, and learn complex configurations without physical hardware is invaluable. For network engineers and DevOps professionals working with Cisco’s Application Centric Infrastructure (ACI) and classic NX-OS environments, one filename stands out as a critical asset: nxosv9k-7.0.3.i7.4.qcow2 . Path: Products → Switches → Data Center Switches
