Allocate sufficient resources (recommended 4 vCPUs and at least 8GB RAM). Key Requirements for Running XRv 9000
: GNS3 will apply default resource bindings. Verify that the RAM allocation is set to a minimum of 16384 MB (16 GB) and that the network adapters use the virtio-net-pci driver for optimized throughput. Verifying the Initial Boot Sequence Always use virtio network drivers in QEMU settings
-cpu host,lvtop1=on -vga std -nographic
: Indicates a complete software package bundle that includes "K9" strong cryptographic capabilities (such as SSH, HTTPS, and IPsec VPN features) required for secure network operations.

| Scenario | How the Image Is Employed | |----------|---------------------------| | | Trainees spin up the image inside a local QEMU instance, gaining hands‑on experience with XR commands, routing protocols, and service configurations without needing physical hardware. | | Software development & testing | Vendors of network‑oriented applications (e.g., SD‑N controllers, telemetry collectors) use the image to validate compatibility with XR 7.1.1 features. | | Proof‑of‑concept (PoC) labs | System integrators build multi‑node topologies (e.g., two XRV9k routers linked by virtual interfaces) to showcase a solution before committing to a real deployment. | | Continuous Integration (CI) | Automated pipelines launch the image, apply configuration scripts, run functional tests, and destroy the VM, ensuring regressions are caught early. |
The IOS XRv 9000 is a heavy, resource-intensive virtual machine because it emulates high-performance service provider architecture. It splits functions into a Virtual Control Plane (VCP) and a Virtual Data Plane (VDP). Minimum Resource Allocations
: The QCOW2 format is highly compatible with EVE-NG (Intel VT-x required). Large File Size
Do not try to run multiple XRv 9000 nodes on a machine with limited RAM. Conclusion
