Without KVM support (fallback to software emulation):
If you come from a VMware-heavy background, you might ask, "Why not .vmdk ?" The answer lies in automation and scale.
This image is heavily utilized by network engineers, candidates studying for Nokia's Service Routing Certification (SRC) program, and architects to simulate production-grade IP/MPLS networks safely in software. Key Features of SR OS 13.0.R4
: Service Router, indicating the software mimics the 7750 SR or 7950 XRS hardware platforms. Timos-sr-13.0.r4-vm.qcow2
: Testing network configuration scripts (Netconf, Ansible, Python) against a virtual router before pushing changes to production hardware.
Assuming a Linux host with KVM:
Technically, TiMOS images require a valid license file from Nokia to boot beyond a trial period or to enable certain line card functions. Final Verdict Without KVM support (fallback to software emulation): If
What are you planning to use? (EVE-NG, GNS3, KVM)
: The forwarding plane in these simulator versions is often rate-limited (e.g., to 250 pps per interface).
: It runs the exact same binary code as the physical hardware, offering the same operational behavior for protocols. Advanced Protocol Support (EVE-NG, GNS3, KVM) : The forwarding plane in
: Intel e1000 or VirtIO network interfaces. Using outdated drivers like i82557b will cause interface connectivity failures inside the SR-OS topology. 2. Setting Up Timos-sr-13.0.r4-vm.qcow2 in EVE-NG Virtual 7750 SR Available in 12.0.R4 - Alcatel Unleashed
To run this image in a simulation environment like GNS3 , the following resources are generally required: : At least 2048 MB .
To run a single instance of this software efficiently, allocate the following hardware resources: : 1 to 2 cores.
Inside the EVE-NG file system, the QEMU hard disk image must be named exactly hda.qcow2 for the system to boot it properly. Navigate to the folder and rename the file:
If you are running a Linux host with KVM enabled, you can spin this up directly. Here is a conceptual example of the command structure you might use:
