Nxosv9k-7.0.3.i7.4.qcow2 File

If your automation uses Ansible, NAPALM, or Netmiko to push configs to NX-OS, a virtual N9K allows safe regression testing. The 7.0.3.I7.4 image supports RESTCONF and NETCONF (though not fully OpenConfig compliant).

If you run a topology with eight Nexus 9kv switches (leaf+spine), apply these optimizations to your hypervisor:

In specific scenarios (e.g., ACI Virtual Edge or bare-metal cloud deployments), the N9Kv acts as a software switch bridging physical and virtual workloads. nxosv9k-7.0.3.i7.4.qcow2

virsh define n9kv.xml
virsh start n9k-lab
virsh console n9k-lab

The boot process takes 4–6 minutes. You’ll eventually see the loader> prompt, then the NX-OS login.

If your physical N9K farm runs version 7.0(3)I7(4), this .qcow2 allows you to test configuration migration or new feature enablement offline. If your automation uses Ansible, NAPALM, or Netmiko

| Attribute | Value | |-----------|-------| | Filename | nxosv9k-7.0.3.i7.4.qcow2 | | Platform | Cisco Nexus 9000v (virtual NX-OS) | | Version | 7.0(3)I7(4) | | Format | QCOW2 (QEMU Copy-On-Write v2) | | Typical use | GNS3, EVE-NG, VIRL, or manual QEMU/KVM |

Cause: Incorrect disk bus type. NX-OS expects virtio-blk, not virtio-scsi or IDE.
Fix: In your VM XML or EVE-NG node configuration, explicitly set disk bus to virtio-blk. virsh define n9kv
