Title: Lab Ready: Exploring the Legacy IOS XRv “K9” Demo Image (6.1.3)

Introduction If you have spent any time building a home network lab for Cisco certification or feature testing, you have likely come across the file iosxrv-k9-demo-6.1.3.qcow2. Despite being an older release (IOS XR version 6.1.3), this image remains a lightweight, valuable tool for testing MPLS, routing protocols, and basic XR CLI structure.

In this post, I’ll cover what this file actually is, how to use it in QEMU/KVM, and the limitations of the “demo” edition. Iosxrv-k9-demo-6.1.3.qcow2

What is iosxrv-k9-demo-6.1.3.qcow2?

This image is designed for proof-of-concept and learning, not production.

Requirements

Basic QEMU Command

qemu-system-x86_64 \
  -machine pc \
  -cpu host \
  -smp 2 \
  -m 4096 \
  -drive file=iosxrv-k9-demo-6.1.3.qcow2,if=virtio \

Note: Adjust network to bridge or macvtap if you need external access.

First Boot & Licensing

  1. The console will output standard IOS XR boot messages.
  2. After booting, you will see:
    RP/0/RP0/CPU0:ios#
  3. The image runs in demo mode—no license file is required, but it will reload every 60 minutes (typical demo limitation).
  4. To check status:
    show license
    show version

Configuration Example

configure terminal
hostname XRv-Demo
interface GigabitEthernet0/0/0/0
 ipv4 address 192.168.1.1 255.255.255.0
 no shutdown
 commit

Run show ipv4 interface brief to verify.

Key Limitations to Know | Feature | Demo Status | |---------|--------------| | Throughput | Limited to ~100k pps | | Uptime | Resets every 60 minutes | | Interfaces | 2–3 usable virtio interfaces | | Crypto (IPsec) | Present but slow | | XR HA (NSR) | Disabled |

Where to Find This Image This image is no longer on Cisco’s official download portal (CCO) for new users. It exists in older lab archives, VMware OVA conversions, and community backup repositories. Do not download from untrusted torrents. Instead, check:
