GNS3 is the most popular tool for running this image.
The iosxrv-k9-demo-6.1.3.qcow2 remains a foundational tool for learning Cisco IOS XR. Its balance of low resource requirements and functional feature set makes it an ideal choice for building a virtual lab to master BGP, MPLS, and network automation. By understanding its limitations and properly deploying it in GNS3 or EVE-NG, you can gain valuable, hands-on experience with carrier-grade routing technology.
Move iosxrvk9demo613qcow2 to your VM storage location (e.g., /var/lib/libvirt/images/ ). iosxrvk9demo613qcow2
The IOS XR 6.1.x branch introduced robust Segment Routing (SR-MPLS) support. With , you can build a small SR domain:
Unlike some “toy” emulators, this image includes a working control plane. You can configure BGP, IS‑IS, MPLS, LDP, segment routing, and even some basic telemetry.

: It is frequently used in lab environments like GNS3 or EVE-NG to design and test network topologies.
is a 64-bit operating system, it has high resource demands compared to standard virtual routers Cisco DevNet (16384 MB) is required for stable operation Cisco Learning Network are standard for this image Cisco Learning Network Disk Space : At least of free space Virtualization : You must have KVM acceleration enabled on your host machine or within your GNS3 VM Deployment Guides 1. EVE-NG Installation
This image allows engineers, students, and architects to run Cisco’s high-end service provider operating system, IOS XR, inside virtual lab environments without requiring expensive physical routing hardware like the ASR 9000 series. What is Cisco IOS XRv? Its balance of low resource requirements and functional
Advantages over raw disk images:
Cisco’s IOS XR is known for its modular architecture, high availability, and rich routing protocol suite (OSPF, ISIS, BGP, MPLS, Segment Routing, etc.). The image brings these capabilities to a lightweight virtual machine that can run on any Linux host with KVM support, or even on Windows/macOS using QEMU. It is an indispensable tool for:
While newer versions of CML prioritize the 64-bit IOS XRv 9000 , older "classic" XRv images like this one are often used as lightweight alternatives for simple routing labs. Key Tips for Beginners
