iosxrvk9: Represents the IOS XRv 9000 platform, which is the virtualized version of Cisco's service provider operating system.
demo: Indicates this is a trial/evaluation version. While it provides full control plane features, it usually has significant throughput throttling (e.g., 100 Kbps to 1 Mbps) and lacks a production license. 613: Corresponds to software version 6.1.3.
qcow2: The standard disk image format for QEMU/KVM virtualization environments. Implementation Guide
To get this specific image "updated" and running in a lab environment, follow these standard steps:
Resource AllocationThis image is resource-heavy. Ensure your host machine or server meets the minimum requirements per instance: CPU: 4 vCPUs.
RAM: 16 GB (8 GB is often the absolute minimum for booting, but 16 GB is recommended for stability). Disk: ~4 GB of initial space. Environment Setup
EVE-NG: Create a folder named iosxrvk9-6.1.3 in the /opt/unetlab/addons/qemu/ directory. Rename the file to virtioa.qcow2 before starting the node.
GNS3: Use the GNS3 Cisco IOS XRv 9000 appliance template to ensure the correct QEMU flags (like -machine type=pc-1.0,accel=kvm) are applied automatically.
Booting & Initial ConfigThe first boot can take 5–10 minutes. Once you reach the prompt, you must create a root user immediately:

Platform: This file belongs to the Cisco IOS XRv family, a virtualized platform for the Cisco IOS XR operating system designed for simulation and testing environments like CML (Cisco Modeling Labs), GNS3, and EVE-NG.
Version 6.1.3: This specific version is a legacy 32-bit "classic" release. While it remains functional for basic network topology testing, it has been largely superseded by the 64-bit IOS XRv 9000 (often referred to as "Sunstone").
File Format (.qcow2): This format is standard for use in KVM (Kernel-based Virtual Machine) and OpenStack environments. Status and Limitations
Demo-Locked: The "demo" designation indicates this image is for evaluation and testing. It typically includes hard-coded default credentials (such as admin/admin or cisco/cisco) that cannot be changed.
Lifecycle Status: IOS XRv version 6.x images are currently deprecated. Cisco has issued End-of-Life (EoL) notices for these demo images, meaning they no longer receive official technical support or new feature updates.
Functionality Gaps: Because it is an older 32-bit image, it may lack support for modern features like Segment Routing or newer EVPN implementations that are standard in later versions like 7.x or the current 24.x/25.x releases. Update Implications

Cisco IOS XRv 9000 Demo Image Updated: iOSXRv-k9-demo-6.1.3.qcow2
Great news for network engineers and virtual lab enthusiasts: the Cisco IOS XRv 9000 demo image has been updated to version 6.1.3. This specific virtual disk image file—iosxrvk9demo613qcow2—is now available for those looking to simulate high-end service provider routing in environments like EVE-NG, GNS3, or standard KVM/QEMU. Why Version 6.1.3 Matters
The 6.1.3 release brings a more stable foundation for the IOS XRv 9000 (often referred to as the XRv9K). Based on the same software used in Cisco’s ASR 9000 and NCS series, this update allows you to test:
Advanced Segment Routing (SR): Enhanced support for SR-TE and traffic engineering.
EVPN Features: Expanded Ethernet VPN capabilities for modern data center and SP architectures.
Performance Stability: Improved memory handling in virtual environments compared to the older 6.0.x builds. Key Specifications Filename: iosxrv-k9-demo-6.1.3.qcow2
Format: QCOW2 (QEMU Copy-On-Write), perfect for thin provisioning.
Min Resources: While it's a demo, the XRv9K is resource-heavy. Expect to allocate at least 4 vCPUs and 16GB of RAM per node for a smooth experience. How to Use It in Your Lab
If you are updating your existing lab, here is the quick workflow:
Download: Obtain the image from the Cisco Software Central (requires a valid CCO ID). Import:
For EVE-NG: Create a folder named xrv9k-6.1.3 and upload the file renamed as virtioa.qcow2.
For GNS3: Use the IOS XRv 9000 appliance template and point it to the new 6.1.3 file.
Initial Boot: Remember that the first boot can take 5–10 minutes as the control plane initializes. Demo Limitations
As a "demo" image, be aware that there is a throughput cap (usually limited to ~2 Mbps) and a nag message regarding the lack of a license. However, for feature testing, protocol validation (BGP, OSPF, ISIS), and API scripting with NETCONF/YANG, this version remains an essential tool.
Happy Labbed! Have you tried running 6.1.3 in your environment yet? Let us know if you've noticed any performance gains over 6.0.x in the comments.
