Add -smp 2 to the Additional Settings section to enable two CPUs for faster booting. 5. Finalize
The hypervisor options include KVM/QEMU installed on CentOS 6.5, CentOS 7.0, or Red Hat Enterprise Linux 7.0.
If you come from a VMware-heavy background, you might ask, "Why not .vmdk ?" The answer lies in automation and scale.
: Ensure QEMU is installed on your system. For graphical management, tools like virt-manager can be invaluable. Timos-sr-13.0.r4-vm.qcow2
: You can fine‑tune the QEMU command to improve stability. A recommended set of parameters includes:
. In this case, "SR" stands for Service Router, and "vm" indicates it is the virtualized flavor (vSR) optimized for hypervisors like QEMU and KVM. Setting Up the Environment
Run the native EVE-NG script to apply the correct permissions and ownership to the new files: /opt/unetlab/wrappers/unl_wrapper -a fixpermissions Use code with caution. Step 4: Configure the Node Template Add -smp 2 to the Additional Settings section
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.
It is important to distinguish between two Nokia products. The Timos-sr-13.0.r4-vm.qcow2 runs , which is the classic, highly mature carrier-grade OS. It is distinct from SR Linux , a newer, modern, cloud-native NOS based on Linux. While SR OS is run as a QEMU VM, SR Linux is distributed as a free, lightweight container image ( ghcr.io/nokia/srlinux ) that is native to Docker and Containerlab.
The file is
Indicates that the software is tailored to run as a Virtual Machine (vSR) rather than on bare-metal proprietary hardware.
timos-sr-13.0.r4-vm.qcow2 is not just a file. It is a packaged for the DevOps era. Whether you are validating an SR-MPLS TE policy, testing EVPN Type-5 route leaking, or building a multi-vendor interoperability lab, this QEMU image is your digital sandbox.
