Use the GNS3 Registry to get the .gns3a template. Import to GNS3: Open GNS3 -> File -> Import Appliance.

The 2 Mbps rate limit is a hard-coded restriction. While this is sufficient for learning routing protocols (OSPF, BGP, IS-IS) and verifying configurations, it makes the demo version unsuitable for any production or high-throughput testing scenario.

Execute EVE-NG’s global wrapper script to restore ownership and execution contexts: /opt/unetlab/wrappers/unl_wrapper -a fixpermissions Use code with caution. 2. Deployment in GNS3 (Graphical Network Simulator-3)

The iosxrvk9demo613qcow2 is a (QEMU Copy On Write) virtual machine image representing a 64-bit Cisco IOS XR version 6.1.3 router. Platform: IOS XRv (Virtual) Version: 6.1.3 (a mature, stable release) Format: QCOW2 (Native to QEMU/KVM-based emulators) iosxrvk9demo613qcow2

Stands for QEMU Copy-On-Write 2 . This is the native disk image format for the QEMU/KVM hypervisor stack. It supports thin provisioning (the file occupies only the space actually used by the guest OS) and VM snapshots. Share public link

As the virtual interface turned green, the traffic graphs on the main monitor began to climb. The "demo" image, meant for labs and testing, was now holding the weight of a million users. It wasn't permanent, but for the next six hours, iosxrv-k9-demo-6.1.3.qcow2 was the hero the internet needed. Use the GNS3 Registry to get the

If you are a Cisco Learning Partner or have a service contract, you may also access the image via Cisco’s VIRL (now CML – Cisco Modeling Labs) repositories. The name sometimes appears in CML‑2.0 node definitions.

If you’ve spent time in the world of network engineering, you know that getting hands-on with high-end Service Provider gear like the can be a challenge. That’s where virtual images like iosxrvk9-demo-6.1.3.qcow2 come into play.

QCOW2 (QEMU Copy-On-Write version 2) is the standard disk format for: While this is sufficient for learning routing protocols

Advantages over raw disk images:

It cannot be used for high-bandwidth traffic testing or performance profiling.
