This file (qcow2) is specifically designed to be imported into network simulation tools.

Summary: You have a Cisco IOS XRv 9000 virtual router image, version 6.1.3, with strong encryption enabled, formatted for QEMU/KVM virtualization. It represents a fully functional virtual core router suitable for lab testing, network simulation, or software development.

iosxrv-k9-demo.6.1.3.qcow2 is a virtual image for the Cisco IOS XRv router, typically used for network simulation and lab testing. This specific version is a "demo" release, which is a lightweight version of the IOS XR operating system designed for trial and educational use. System Requirements

To run this image smoothly, your virtual environment (GNS3, EVE-NG, or KVM) should meet the following minimum specs: Memory (RAM):

Minimum 3 GB (3072 MB); 4 GB is recommended for better performance.

1-2 vCPUs (Intel Nehalem or later with 2.0 GHz clock speed recommended). iosxrvk9demo613qcow2 top

The image itself is approximately 429 MB, but the virtual disk should be allocated at least 3 GB. Hypervisor: Requires KVM support. It is best used within a environment. Installation Guide 1. Using with EVE-NG Create Directory:

Access your EVE-NG CLI via SSH and create a folder for the image: mkdir /opt/unetlab/addons/qemu/iosxrv-k9-6.1.3 Upload Image: Use an SFTP client (like WinSCP or FileZilla) to upload the file to that new directory. Rename File: The file must be named virtioa.qcow2 for EVE-NG to recognize it. Fix Permissions: Run the following command in the EVE-NG CLI: /opt/unetlab/wrappers/unl_wrapper -a fixpermissions 2. Using with GNS3 Download Appliance: Cisco IOS XRv appliance file from the GNS3 Marketplace. In GNS3, go to File > Import appliance and select the file you downloaded. Select Version: Choose version and point GNS3 to your local iosxrv-k9-demo.6.1.3.qcow2 Finish Setup:

GNS3 will automatically configure the correct RAM and CPU settings based on the appliance template. Initial Setup & Usage First Boot: You will be prompted to set an admin username and password on the first successful boot. Two-Stage Configuration:

Unlike standard IOS, IOS XR uses a two-stage config. You must type after entering commands for them to take effect.

The device typically uses a serial console for management. Ensure your terminal emulator is set to Telnet or VNC as specified in your lab software. to your physical network? Cisco IOS XRv - GNS3

The filename iosxrv-k9-demo-6.1.3.qcow2 refers to a virtual machine disk image for Cisco IOS XRv, a virtualized version of Cisco's high-end Service Provider operating system. This specific version (6.1.3) is a "demo" release, commonly used by network engineers for labbing features like BGP, OSPF, and Segment Routing without needing $100k+ physical hardware.  Core Specifications & Use Case 

Operating System: 64-bit IOS XR (eXR), which runs on a Linux-based kernel (Wind River Linux).

Format: .qcow2 (QEMU Copy-On-Write), optimized for KVM-based hypervisors like GNS3, EVE-NG, or Cisco Modeling Labs (CML). Hardware Requirements: vCPU: 1 (minimum) to 4 (recommended for stability).

vRAM: 3GB to 4GB is the baseline; it may boot with 2GB but will likely crash during BGP convergence or heavy config application. Disk: ~3GB to 4GB.  Deep Technical Write-Up & Setup  1. Image Preparation  Username: demo Password: demo Enable password: (none, just

To use this in a lab environment like EVE-NG, you must rename the file to fit the platform's naming convention (e.g., hda.qcow2) inside a folder named xrv-k9-6.1.3. Guides from EVE-NG Documentation provide the exact folder structure needed for the image to be recognized.  2. Virtualization Parameters 

When running this image via QEMU, specific flags are required to ensure the CPU is emulated correctly:  CPU Mode: host-passthrough or IvyBridge.

NIC Type: virtio-net-pci is preferred for throughput, though e1000 is more compatible for basic labs.

Console: Serial console access is required. IOS XR takes significantly longer to boot (3–5 minutes) than standard IOS because it initializes a full Linux microkernel first.  3. The "Demo" Limitation 

The demo tag indicates this is a free-to-download image for evaluation. 

Throughput Cap: Most demo versions are throttled to 2 Mbps or 10 Mbps of data plane traffic. This makes it useless for production but perfect for learning control-plane protocols.

No Support: There is no official Cisco TAC support for these images.  4. Common Commands for Initial Access  Once the image boots, you will encounter the ios login.  Default Credentials: Usually admin/admin or cisco/cisco.

Initial Setup: Unlike standard IOS, you must enter "Config" mode and commit changes for them to take effect.

While newer versions like 7.x exist, 6.1.3 remains popular in the labbing community because it is relatively lightweight compared to the 8GB+ RAM requirements of the newer "IOS XRv 9000" series. It supports most Segment Routing and EVPN features needed for the CCIE Service Provider exams. 

For further automation, you can wrap this image into a Vagrant box for quick deployment of multi-node topologies. 

Here’s a solid, practical guide for working with the iosxrvk9demo-6.13.0.qcow2 image — often found in Cisco’s XRv 9000v demo VM for EVE-NG, GNS3, or KVM.

Note: Filename may vary slightly (e.g., iosxrvk9demo-6.13.0.qcow2), but the guide applies to all 6.x demo versions.

When users add “top” to the image search, they likely want to know how to monitor the virtual router’s resource consumption using the Linux top utility.

Let’s break down the probable intended components:

| Fragment | Meaning | |----------|---------| | iosxrv | Cisco IOS XR Virtual (the XRv series) | | k9 | Encryption capability (strong crypto) | | demo | Demo/trial version (time or feature-limited) | | 613 | Possibly version 6.1.3 (a known IOS XR release) | | qcow2 | QEMU Copy-On-Write v2 disk format | | top | Linux process monitor – likely referring to top -p <pid> to check VM resource usage |

A plausible correct filename would be:
