Using unverified images like iosxrvk9demo613qcow2 risks:
disk image format, which is the standard format for virtual machines running on KVM hypervisors. Overview of Cisco IOS XRv 9000 iosxrvk9demo613qcow2
Don't underestimate the power needed to run this "demo" image. IOS XR is a heavy, multi-process OS. Minimum recommended specs for a single instance of 6.1.3 are: : 2 to 4 cores.
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)
If you encounter difficulties locating or using this specific image, note that newer versions (e.g., 7.x, 24.x) include significant feature enhancements like Segment Routing v6, programmable APIs, and improved virtualization support. Consider starting with a more recent xrv9k-fullk9-x image for full production capability without demo restrictions.
When you see a .qcow2 file, you typically boot it with: EVE-NG handles QCOW2 images natively
The string resembles a from an internal lab or a repackaged unofficial image. Cisco’s official images follow a more structured naming convention like iosxrv-fullk9-x-6.3.2.qcow2 .
As a demo version, expect throughput limits. It is designed for control-plane testing (routing protocols), not for pushing high-speed production traffic.
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.

"Demo" version, typically used for evaluation and familiarization with the control plane and CLI. System Requirements: The virtual machine generally requires at least 3072 MB (3 GB) of RAM to operate effectively. Usage in Simulation Labs
Once the VM is powered on, open the console.
The iosxrvk9demo613qcow2 image is an essential resource for network engineers looking to specialize in service provider technologies. By offering a lightweight yet functional Cisco IOS XR environment, it provides an accessible bridge between theoretical knowledge and practical, hands-on experience, making it ideal for simulation in labs like EVE-NG or GNS3.
The Cisco IOS XRv 9000 is the virtualized counterpart of Cisco’s flagship service provider operating system, IOS XR. Unlike the older, more lightweight IOS XRv, the is based on the same 64-bit IOS XR software found on high-end hardware like the ASR 9000 and NCS series.
