This image functions as a standard building block in multi-vendor network emulation environments. IOS XRv - Cisco Modeling Labs v2.10
To use this in GNS3, you should use the IOS XRv appliance template: Open GNS3 and go to . Select the cisco-iosxrv.gns3a file.
While newer versions like 7.x exist, version 6.1.3 is often cited in community forums as a "sweet spot" for stability in virtualized environments with limited hardware resources. It supports standard SP features such as: (including Prefix-Sets and Route-Policies) OSPF/IS-IS and L3VPNs Segment Routing (basic functionality) iosxrv-k9-demo-6.1.3.qcow2 Iosxrv-k9-demo-6.1.3.qcow2

Here is a comprehensive guide to understanding, deploying, and using this specific image in your lab. What is IOS XRv?
Rename the file to the EVE-NG standard name: mv Iosxrv-k9-demo-6.1.3.qcow2 hda.qcow2 While newer versions like 7
While newer images exist, iosxrv-k9-demo-6.1.3.qcow2 represents a golden era for network emulation. It offers the perfect balance of modern routing protocol support (Segment Routing, BGP-EVPN fundamentals) and lightweight performance.
Always ensure you have the proper licensing from Cisco to use their software images. The demo images are intended for evaluation and non-production laboratory environments.
iosxrv-k9-demo-6.1.3.qcow2 is a Cisco IOS XRv virtual router disk image distributed in QCOW2 format for use with hypervisors (QEMU/KVM). It provides a virtualized instance of Cisco IOS XR software intended for lab, demo, and development purposes. This build (6.1.3) corresponds to the IOS XR release train with features and behavior typical of the 6.x series.
