Newer versions of GNS3/EVE-NG now support improved qemu arguments to run this image with better stability, specifically regarding CPU usage.
If you encounter issues during boot, consider the following:
It offers a balanced footprint, capable of running on modern laptops with 16GB RAM.
Cisco IOS XRv 9000 Demo Image Updated: iOSXRv-k9-demo-6.1.3.qcow2
Use the cisco.iosxr Ansible collection to push configurations or gather facts from your legacy demo node.
Don't panic if it looks stuck. The initial boot can take 5–10 minutes as the OS initializes its internal databases. Demo Mode Limits: Because this is the "demo" version, it is typically rate-limited
When configuring the node in your virtualization platform, ensure the following arguments are passed to the QEMU process:
Be patient. Monitor the console output to see it loading the kernel. 3. "No Licence Found" Messages
Just updated my simulation environment with the iosxrv-k9-demo-6.1.3.qcow2 image. For those labbing Service Provider features or studying for the CCIE Service Provider, this remains a reliable reference platform for IOS-XR control plane features. Platform: Cisco IOS XRv (Demo Version) Format: QCOW2 (Optimized for KVM/QEMU) Requirements: Minimum 3GB RAM recommended.
: If you exit without typing commit , your changes are discarded. Always execute: RP/0/RSP0/CPU0:iosxrv(config-if)# commit Use code with caution. Limitations: Feature Gaps and Upgrade Alternatives
Fix: Your hypervisor configuration likely lacks sufficient RAM. Ensure you have allocated a full 16 GB of memory. IOS XRv requires a heavy initial footprint to uncompress its system image into memory.
