Timos-sr-13.0.r4-vm.qcow2 !exclusive! Jun 2026

Upload the Timos-sr-13.0.r4-vm.qcow2 file to the newly created directory using an SFTP client (like WinSCP or FileZilla). Once uploaded, rename the file to virtioa.qcow2 so that the EVE-NG QEMU process recognizes it as the primary boot drive:

The QCOW2 format makes this image highly compatible with Linux-based emulation software:

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.

A common use case for the .qcow2 image is to use it within the EVE-NG (Emulated Virtual Environment) Professional Community Edition, a popular network emulator. Here is the process: Upload the Timos-sr-13

Nokia (formerly Alcatel-Lucent) Service Router Operating System (SR OS) , specifically version In the Nokia ecosystem,

If you are running the image manually via the command line, use a string similar to this: /usr/local/bin/qemu-system-x86_64 -m MB -enable-kvm \ -hda TiMOS-SR- The virtualized Service Router (VSR) is a network

Because it is a full router, you can test control plane vulnerabilities, BGP Flowspec policies, or DDoS mitigation techniques without risking hardware.

: Virtualized Simulator (vSim), which provides the functional equivalent of the control and management planes of a physical 7750 SR router. : 13.0.R4 (Release 13, Maintenance Release 4).

If you are running multiple 7750 routers (e.g., 6 instances), you may encounter performance issues. It is recommended to boot them one by one rather than all at once to avoid system instability in the GNS3 VM.
