One specific version often discussed in lab environments—particularly for tools like GNS3, EVE-NG, or Vagrant—is the iosxrv-k9-demo-6.1.3.qcow2 Why This Specific Version?
The 6.1.3 demo image is a popular "middle ground" for virtualization: Low Resource Footprint:
Unlike the newer IOS-XRv 9000 images, which can require upwards of 16GB of RAM, this classic IOS-XRv image generally runs on just 3GB of RAM Demo Accessibility:
It was widely available as a demo image for evaluation, making it a staple for those building home labs on a budget. Cross-Platform Compatibility: iosxrvk9demo613qcow2 exclusive
format is natively supported by QEMU/KVM, which is the engine behind Setting Up Your Environment Whether you are using
, Vagrant, or KVM, the setup process for this image is relatively standardized: Preparation: If you have the image in format, you can easily convert it to to make it compatible with Linux-based hypervisors. Resources:
Ensure your host machine has at least 3072 MB of RAM allocated to the VM and that KVM hardware acceleration is enabled in your BIOS/Settings.
On the first boot, you will typically be prompted to set an admin username and password. Remember that IOS XR uses a two-stage configuration ; changes aren't live until you use the Limitations to Keep in Mind
While great for learning basic BGP, OSPF, and MPLS, the 6.1.3 image is showing its age: End of Life:
Cisco has officially moved toward newer versions, and this specific demo image is now considered legacy. Missing Features: If you are looking to test cutting-edge features like Segment Routing (SR-TE)
, Flex Algo, or PCEP, version 6.1.3 may fall short. For those features, you might need to hunt down the newer IOS-XRv 9000 or the 6.3.1 images. Conclusion iosxrv-k9-demo-6.1.3.qcow2

It’s perfect for learning the CLI and basic routing protocols without killing your laptop's performance. topology or configuration guide to get started with this image in your lab? What specific networking features are you planning to test with this image?
The iosxrv-k9-demo-6.1.3.qcow2 is a virtual image for the Cisco IOS XRv Router , a 64-bit virtualized platform designed to simulate Cisco’s IOS XR operating system for lab and demonstration purposes. This "exclusive" demo version allows network engineers to test advanced routing features like BGP, OSPF, and MPLS in virtual environments like GNS3 or EVE-NG without requiring physical hardware. 1. Hardware & System Requirements
Running this image requires significant resources due to its 64-bit architecture. RAM: Minimum 3072 MB (3 GB) per instance.
CPU: A modern processor supporting Intel VT-x or AMD-V virtualization.
Hypervisor: Must support KVM (Kernel-based Virtual Machine) for optimal performance. 2. Setup in GNS3
GNS3 is the most common platform for this specific demo image.
Download Appliance: Obtain the .gns3a appliance file from the GNS3 Marketplace.
Import Image: Open GNS3 and go to File > Import appliance. Select the .gns3a file and follow the wizard to link your iosxrv-k9-demo-6.1.3.qcow2 file.
GNS3 VM: Ensure you are running the image on the GNS3 VM (Linux-based) rather than your local host to utilize KVM acceleration. 3. Setup in EVE-NG
IOS XRv-k9-demo-6.1.3 is a virtualized platform developed by Cisco to simulate the IOS XR operating system within lab environments for testing and educational purposes. This specific version, delivered as a QCOW2 (QEMU Copy-On-Write) disk image, is a staple for network engineers using virtualization tools like GNS3, EVE-NG, or Cisco Modeling Labs (CML) to master high-end routing protocols without physical hardware. Architectural Significance and Deployment
The "demo" designation signifies that this image is intended for control-plane testing, supporting features like BGP, OSPF, and IS-IS. Because it is a virtual machine (VM), it lacks a hardware-based data plane, meaning it is not suitable for high-throughput production traffic but is ideal for validating configurations and automation scripts.
Deploying iosxrv-k9-demo-6.1.3.qcow2 typically involves a few technical steps depending on the hypervisor:
Virtualization Platforms: It is commonly used in GNS3 and EVE-NG to build complex network topologies.
Image Conversion: While the native format is often QCOW2, users on platforms like VMware Fusion may need to convert the file from .vmdk using tools like qemu-img.
Resource Requirements: The appliance generally requires approximately 3GB of RAM and KVM acceleration to function smoothly within a virtual environment. Operational Use Cases
For many engineers, this image serves as an entry point into the IOS XR ecosystem, which powers Cisco’s service provider-grade hardware like the ASR 9000 series. It allows for: Filesystem inside – Usually a split image: ISO
Protocol Testing: Users can establish L3 connectivity, run IGPs, and test iBGP peering between different virtual nodes.
Configuration Mastery: It supports the "two-stage" configuration model unique to IOS XR, where changes must be explicitly committed before they take effect.
Automation Development: Providing a lightweight environment for testing Python scripts or Ansible playbooks against a real IOS XR CLI. Conclusion

This review covers the iosxrvk9demo613qcow2 image, an exclusive, compact virtual machine file used for emulating Cisco IOS XRv on platforms like GNS3, EVE-NG, or KVM. Bottom Line
Yes, it's an excellent, lightweight, and exclusive resource for learning Service Provider technologies, but it's essential to understand its limitations for modern production simulations. Review: iosxrvk9demo613qcow2
Core Purpose: This specific image (often titled "Demo" or "K9") is designed specifically for testing, labs, and educational purposes. It brings Cisco's IOS XR operating system to virtualized environments without requiring the massive resource footprint of full-featured XRv-9000 images. Key Strengths:
Low Resource Usage: It is designed to run efficiently on limited hardware, making it ideal for running multiple nodes in GNS3 or EVE-NG [1].
Core Feature Set: It provides full access to core IOS XR CLI, basic routing protocols (OSPF, ISIS, BGP), and Multiprotocol Label Switching (MPLS) features.
"Exclusive" Access: These "demo" images are often sought after because they are lighter than commercial variants, making them ideal for quick lab prototyping. Performance & Compatibility:
Version: Often based on 6.1.3, which is stable for learning basic to intermediate XR concepts [1].
Stability: It is highly stable for control-plane simulations (BGP, OSPF). Limitations:
No ASIC/Data Plane Simulation: Because it is a "demo" image, it does not support advanced traffic engineering, deep hardware-specific features, or high-throughput data plane simulations.
No Modern Features: It lacks modern features found in 7.x or later versions. Verdict
If you are preparing for SPCOR (350-501), CCIE Service Provider, or just learning IOS XR, this image is a perfect, highly recommended, and fast-acting tool. However, it is not suitable for complex data plane simulations or testing modern production-level XR features.
