Great news for network engineers and virtual lab enthusiasts: the Cisco IOS XRv 9000 demo image has been updated to version . 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 standard disk image format for QEMU/KVM virtualization environments. Implementation Guide
Whether you are updating your local image library for Cisco Modeling Labs (CML), GNS3 , or EVE-NG , maintaining the exact 6.1.3 version helps test architectural control planes like BGP, OSPF, and basic MPLS without running high-resource heavier platforms.
While the updated 6.1.3 demo image remains an agile, low-resource option for staging standard ISP architectures, it possesses definite boundaries. If you are looking to lab-test advanced, cutting-edge architectures like , PCEP , or extensive SRv6 (Segment Routing over IPv6) implementations, this version will fall short. For those advanced toolsets, you will need to pivot to modern releases within the Cisco Modeling Labs (CML) ecosystem or deploy the resource-heavy IOS XRv 9000 platform. iosxrvk9demo613qcow2 updated
The iosxrvk9-demo.6.1.3.qcow2 file is a virtual disk image that runs the 32-bit Cisco IOS XR software . It is designed for demonstration and educational purposes, offering a "demo" capability that allows the image to run without requiring a permanent license file, which is ideal for EVE-NG users looking for rapid deployment. 6.1.3 Architecture: 32-bit (x86)

The xrv9k-fullk9-x.qcow2 (or similar naming) is a standard QCOW2 disk image containing a pre-installed instance of the IOS XRv 9000 Router, ready for deployment in KVM environments. Great news for network engineers and virtual lab
This creates an XRv VM with 4GB RAM, a qcow2 hard disk, and mounts the configuration ISO for automated setup.
Enhanced support for SR-TE and traffic engineering.
