Timos-sr-13.0.r4-vm.qcow2 [updated] -

To save disk space and boot multiple instances rapidly, use qemu-img to create a backing file chain. Instead of copying the base image for every node, create a derivative image:

Timos-sr-13.0.r4-vm.qcow2 is more than a file; it is a philosophy. It encapsulates the shift from "bare metal" to "anything-as-a-service." By taking the complex, stateful logic of a carrier router and sealing it into a portable, efficient, and virtualizable disk image, Nokia and the open-source community have democratized access to high-end networking. For the network engineer of 2025, this single file is a sandbox, a classroom, and a production tool—all contained within 2 gigabytes of digital storage. It proves that in the modern era, the most powerful routers are no longer measured in rack units, but in megabytes.

Once the VM boots, you aren't dropped directly into a shell. You have to navigate the Nokia boot sequence.

EVE-NG is a widely used platform for hosting virtual network nodes. Follow these structural steps to integrate the Nokia image into an EVE-NG topology. Step 1: Create the Directory

This article provides an in-depth look at this image, covering its use cases, system requirements, and how to set it up in a GNS3 environment. What is TiMOS-SR-13.0.R4-vm.qcow2?

Before attempting to boot the image, it is essential to ensure your lab environment meets the necessary requirements. The TiMOS-SR-13.0.R4-vm is an x86 QEMU-based appliance.

If the VM appears to be "stuck" or hangs during boot, ensure that the KVM acceleration is correctly enabled ( kvm-ok command). Additionally, confirm that the QEMU machine type ( -machine pc ) matches the hardware expectations of the TiMOS kernel.

Finish the wizard, add the node to your canvas, and start the machine. Access the console to begin configuration. Licensing and Troubleshooting For the network engineer of 2025, this single

To maintain hypervisor stability and prevent CPU or memory oversubscription, the virtual machine (VM) requires a specific bare-minimum baseline:

The .qcow2 file format is a virtual disk image format used by QEMU. It allows for the creation of virtual hard drives, which can be used by virtual machines. The .qcow2 format offers several advantages, including:

The plan involves multiple rounds. In Round One, I will perform several searches to cover different aspects. I'll use search terms based on the keyword, including variations and related terms like "Timos SR", "qcow2", "Nokia SR Linux", "containerlab", "vrnetlab", "network emulation". I'll also search for documentation and the exact filename. search results for "Timos-sr-13.0.r4-vm.qcow2" show a SlideShare page and an Alcatel Unleashed forum post. These seem relevant for basic usage. The search for "Timos SR 13.0.r4 release notes" returned a result that appears to be about a different tool. The search for "Nokia SR Linux qcow2 image download" returned results about Nokia SR Linux, but the keyword is "Timos-sr-13.0.r4-vm.qcow2" which might be related to "Nokia SR OS" (formerly Alcatel-Lucent Service Router Operating System). The search for "sr-13.0.r4" Nokia returned documentation about SR Linux. The search for "containerlab Nokia SR Linux image" returned results about containerlab. The search for "vrnetlab Timos SR Linux" returned results about vrnetlab. The search for "qcow2 virtual machine image network operating system" returned general information about qcow2.

: The --import flag skips OS installation, directly booting the qcow2 disk. The two --network parameters provide at least two virtual ports (required for TiMOS to initialize).

This creates r1.qcow2 , which only stores the changes (deltas) from the base image, drastically reducing storage consumption for multi-node labs.
