: The native Linux kernel-based virtual machine hypervisor.
The primary purpose of this file is to enable network professionals to emulate the full control and management plane of Nokia's carrier-grade routers in a virtual environment. The virtualized Service Router (VSR) is a network function virtualization (NFV) product that provides a virtualized implementation of Alcatel-Lucent's 7750 SR and 7950 XRS routers.
: Virtual images require you to provision the virtual chassis interfaces via the CLI before ports will show an "Up" status.
You can launch the VM directly using the QEMU command line: Timos-sr-13.0.r4-vm.qcow2

This image serves as the core tool for professionals studying for the Nokia Service Routing Certification (SRC) program, including the Network Routing Specialist (NRS I / NRS II) and Service Routing Architect (SRA) designations.
Stands for QEMU Copy-On-Write 2. This is the native disk image format for the QEMU/KVM hypervisor. It is highly optimized for virtualization, supporting features like thin provisioning (the file grows only as data is added) and snapshots.

The .qcow2 file itself is relatively small (typically under 500 MB), but it requires thin provisioning on the host. Software Prerequisites
: Create a folder named exactly starting with timos- inside the EVE-NG image directory: /opt/unetlab/addons/qemu/timos-13.0.R4/ : Virtual images require you to provision the
Nokia’s unique service-centric model separates transport from services. This image allows full simulation of:
It is crucial to note what this file is not . It is not a Linux distribution like Ubuntu; it is a specialized network operating system. It does not have a general-purpose compiler or a GUI desktop. Furthermore, while the control plane (the logic that calculates routes) runs perfectly in a VM, the data plane (the speed at which it forwards packets) is limited. Physical routers rely on ASICs to forward packets at 400 Gigabits per second; the .qcow2 version relies on the host server's CPU, typically maxing out at a few gigabits per second. Therefore, while it is perfect for lab testing, control-plane learning, and edge virtualization, it cannot replace a physical chassis in a core internet backbone.
