Kernel-based Virtual Machine (KVM) acceleration is required for reasonable performance. CPU: 2 vCPUs (recommended: -smp 2 option). Disk Interface: IDE. Network Interface: Intel E1000 emulation is recommended. Timos-sr-13.0.r4-vm.qcow2
Upload your Timos-sr-13.0.r4-vm.qcow2 file into the newly created directory using an SFTP client (like WinSCP or FileZilla). Step 3: Rename the Virtual Disk File
Timos: a network OS designed for routing at scale Timos (short for “TiMOS” in some vendor contexts) is typically a specialized operating system tailored to service-provider routers and switches. It focuses on high-performance packet forwarding, advanced routing protocols (BGP, OSPF, IS-IS), MPLS, traffic engineering, quality of service, and carrier-grade features such as high availability and precise telemetry. Unlike general-purpose OSes, Timos integrates hardware-accelerated forwarding planes with a rich control plane, exposing CLI and APIs for automation. The versioning in the filename—13.0.r4—implies a major release with revisions, each addressing bug fixes, feature additions, or security patches. For operators, specific versions are critical: they determine feature availability, platform compatibility, and known vulnerabilities.
: The forwarding plane in these simulator versions is often rate-limited (e.g., to 250 pps per interface). Minimum 2 GB (4 GB recommended for stable performance)
Widely used for professional-grade service provider labs.

If you come from a VMware-heavy background, you might ask, "Why not .vmdk ?" The answer lies in automation and scale.
: Designates that the software has been packaged with a virtual-friendly driver set to communicate with virtual interfaces rather than physical network processors.
