Although is a “demo” image, it can handle a respectable load for learning purposes:

from ncclient import manager m = manager.connect(host="192.168.122.100", port=830, username="cisco", password="cisco", hostkey_verify=False) print(m.get_config('running').xml)

This is an older release (6.1.3 was End-of-Life / End-of-Support several years ago). While stable for legacy labs, it lacks newer features found in IOS XR 7.x and 24.x (such as Smart Licensing, newer YANG models, and containerized apps). iosxrvk9demo613qcow2

When mapping this translated disk to a new VM in VMware , always configure the boot firmware to use rather than UEFI. Essential Configuration & Operating Behaviors First Boot Execution

You can use the official appliance template to import the image. It generally performs best when running on the GNS3 VM .

: This denotes Cisco IOS XRv (the virtualized variant of the high-end IOS XR operating system used on platforms like the ASR 9000 and CRS series) bundled with standard cryptographic features ( k9 ). Upon booting, the router may take 5–10 minutes

Upon booting, the router may take 5–10 minutes to load for the first time. The default CLI prompt will appear once the system is ready.

The QCOW2 format is not a random choice—it offers specific advantages for network emulation:

The length of a random string can vary greatly, from a few characters to several dozen. The specific combination and length of the string depend on the algorithm used to generate it. IS-IS) and verifying configurations

is a virtual disk image for the Cisco IOS XRv router, specifically version 6.1.3 of the "demo" release. This image allows network engineers to simulate a virtual machine (VM) running the 32-bit IOS XR operating system for education, configuration staging, and network modeling. Technical Overview

The filename iosxrvk9demo613qcow2 is not random—it’s a structured label that reveals the essential characteristics of the software. Cisco follows consistent naming patterns for its virtual images, making it possible to decode similar filenames you might encounter in the future.

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.
