| Scenario | How the Image Is Employed | |----------|---------------------------| | Network‑engineer training | Trainees spin up the image inside a local QEMU instance, gaining hands‑on experience with XR commands, routing protocols, and service configurations without needing physical hardware. | | Software development & testing | Vendors of network‑oriented applications (e.g., SD‑N controllers, telemetry collectors) use the image to validate compatibility with XR 7.1.1 features. | | Proof‑of‑concept (PoC) labs | System integrators build multi‑node topologies (e.g., two XRV9k routers linked by virtual interfaces) to showcase a solution before committing to a real deployment. | | Continuous Integration (CI) | Automated pipelines launch the image, apply configuration scripts, run functional tests, and destroy the VM, ensuring regressions are caught early. |
Because the image is a full‑system appliance, it includes the bootloader, kernel, base OS, and a default configuration that enables remote access (usually via SSH or console). Users typically mount the qcow2 file as a virtual block device, then boot it with a command such as:
qemu-system-x86_64 \
-m 4096 \
-smp 4 \
-drive file=Xrv9k-fullk9-x-7.1.1.qcow2,if=virtio,cache=writeback,format=qcow2 \
-netdev user,id=net0,hostfwd=tcp::2222-:22 \
-device virtio-net-pci,netdev=net0 \
-nographic
The -nographic flag lets you interact with the router’s console directly in the terminal, while the hostfwd rule forwards the guest’s SSH port (22) to the host’s port 2222. Xrv9k-fullk9-x-7.1.1.qcow2 Download

EVE-NG is the preferred emulator for CCIE STP studies. | Scenario | How the Image Is Employed
Create the node in EVE-NG:
Run the fix permissions script:
/opt/unetlab/wrappers/unl_wrapper -a fixpermissions
Start and console. Boot time is ~4-5 minutes. Be patient.
