Use qemu-img info to check the actual virtual size, format, and backing file:

qemu-img info iosxrvk9demo613qcow2

Look for output like:

image: iosxrvk9demo613qcow2
file format: qcow2
virtual size: 4.0 GiB (4294967296 bytes)
disk size: 1.2 GiB

Let’s analyze iosxrvk9demo613qcow2:

| Part | Meaning | |------|---------| | iosxrv | Cisco IOS XRv (virtual version of ASR 9000 series) | | k9 | Indicates cryptographic (encryption) support – typical for export-controlled versions | | demo | Likely indicates a demo, evaluation, or trial image | | 613 | Possibly a build number, date stamp, or arbitrary lab identifier | | qcow2 | QEMU Copy-On-Write version 2 – a disk format used by KVM, Proxmox, and other open-source hypervisors |

The string resembles a custom-named file 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.

Since the filename includes demo, boot the image and attempt to enter EXEC mode:

Router> enable
Router# show version

Look for words like "Evaluation license", "Demo mode", "Time remaining". A demo image may reboot after 60–180 days.

Note: 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).

The iosxrv-k9-demo-6.1.3.qcow2 is a virtual image for the Cisco IOS XRv router, primarily used for lab testing and feature evaluation. It is a 64-bit operating system designed to run as a virtual machine (VM) on hypervisors like KVM and VMware. Key Features and Capabilities

Feature Parity: It provides a similar "look and feel" to physical Cisco ASR 9000 Series Routers, including support for control plane and management plane features.

Lab Compatibility: The .qcow2 format is widely used in network emulation environments like GNS3 and EVE-NG. Virtual Machine Requirements: RAM: Minimum 3 GB (3072 MB) is generally required. Disk Space: The image file size is approximately 429 MB. Known Limitations

Rate Limiting: By default, unlicensed demo images are heavily rate-limited to 200 Kbps, making them unsuitable for significant traffic throughput testing. Feature Constraints: It does not support hardware-specific configurations.

Older demo versions (like 6.1.3) may lack support for cutting-edge features such as Segment Routing (Flex Algo, PCEP) or SRv6, which often require newer versions (e.g., 6.3.1 or 7.x) or the more resource-heavy XRv 9000 image.

End-of-Life: These demo images have reached an End-of-Life notice as Cisco shifts toward newer Cisco Modeling Labs (CML) reference platforms. Performance and Reliability iosxrvk9demo613qcow2

iosxrv: Indicates the IOS XRv platform, which is the virtualized version of Cisco's IOS XR operating system typically used in service provider environments.

k9: Denotes the "K9" crypto payload, meaning the image includes support for strong encryption (like SSH or IPsec).

demo: Specifies that this is a demonstration or evaluation version. These are often used for lab environments, testing, or learning purposes and typically have throughput limitations.

613: Represents the software version, in this case, Cisco IOS XR Release 6.1.3.

qcow2: The file extension for QEMU Copy-On-Write. This is the standard disk format used by virtual machine monitors like KVM, QEMU, and GNS3. Common Use Cases

This specific file is most frequently used by network engineers and students within network simulation tools.

GNS3 / EVE-NG: It is often imported into these platforms to build virtual labs.

Cisco Modeling Labs (CML): While CML often uses newer versions, this older demo image is a common community resource for lightweight testing.

Learning BGP/MPLS: Because IOS XR is a modular, high-end operating system, this image allows users to practice service provider technologies like BGP, MPLS, and Segment Routing without needing $50,000+ hardware. Resource Requirements

To run this image effectively in a virtual environment, you typically need to allocate:

RAM: At least 3GB to 4GB (though it can sometimes boot with 2GB). CPU: 1 vCPU is usually sufficient for demo labs.
