Do not attempt to run this image on a laptop with 8GB of RAM. The XRv 9000 is a heavy-duty virtual router designed to emulate a high-end chassis.
: Finally, Alex ran the command: virsh create xrv9k-fullk9-x.virsh.xml In moments, the router transitioned to a running state, visible through the virsh list command. The Moral of the Story
The XRV9K-fullk9-x-7.1.1.qcow2 image offers a versatile and powerful tool for network simulation, testing, and learning. By following the steps outlined in this guide, users can easily obtain and deploy this virtual appliance, taking full advantage of its extensive feature set. Always ensure to adhere to Cisco's licensing and usage policies when downloading and using their software images.
If you do not have an active enterprise service contract, the most cost-effective legal alternative is purchasing a subscription to . CML includes legally licensed, pre-verified QCOW2 reference platform images for IOS-XR, IOS-XE, and NX-OS that you can use inside CML or export to other lab tools. Initial Boot and Verification Xrv9k-fullk9-x-7.1.1.qcow2 Download
Once you have secured the xrv9k-fullk9-x-7.1.1.tar or .qcow2 file, extract it if necessary. 2. Deploying in EVE-NG EVE-NG is the preferred platform for running XRv9k.

| Question | Answer | |----------|--------| | | No. The virtual XR images are intended for lab, testing, or demonstration purposes only. Production deployments should run on certified hardware with a proper Cisco service contract. | | What hardware architecture does the image target? | The “x” in the filename suggests an x86‑64 (Intel/AMD) build, which is the standard for QEMU/KVM environments. There are also ARM‑based XR images, but they have a different naming convention. | | Is the image compatible with other hypervisors (e.g., VMware, Hyper‑V)? | The qcow2 format is native to QEMU/KVM. For VMware, you would need to convert it to VMDK ( qemu-img convert -f qcow2 -O vmdk Xrv9k-fullk9-x-7.1.1.qcow2 Xrv9k.vmdk ). However, licensing terms still apply, and Cisco may not permit conversion for non‑KVM environments. | | How do I back up the router’s configuration? | Inside XR, use the admin save configuration command to write the running config to the internal flash. For a full VM backup, copy the qcow2 file while the VM is powered off, or use qemu-img snapshot to create a point‑in‑time snapshot. | | What is the difference between XR 7.1.1 and later releases? | XR 7.1.1 introduced enhanced segment routing , native BGP‑LDP interoperability , and improved telemetry . Later releases (7.2.x, 7.3.x) added SR‑v6 , P4 support , and enhanced security hardening . Choose the version that matches the feature set you need to test. |
: This release optimized how the virtual image handles system memory, allowing for smoother performance in lab environments like GNS3, EVE-NG, or Cisco Modeling Labs (CML). Important Note on Downloading
This specific image allows network engineers to simulate high-end Cisco platforms like the NCS 6000 series in a virtual lab. It is frequently used for preparing for certifications like CCIE Service Provider or testing complex BGP and segment routing configurations. The Moral of the Story The XRV9K-fullk9-x-7
