The relevance of iosxrvk9demo613qcow2 is further amplified by the timing of its release. Version 6.1.3 arrived during a pivotal transformation in IOS
Below is an architectural breakdown, deployment guide, and operational overview for using this virtual appliance in modern network labs. 1. What is the IOS XRv 9000 Virtual Appliance?
Operating an advanced enterprise operating system inside a local computer is compute-intensive. Cisco IOS XRv 9000 images are notoriously heavy, requiring substantial allocation changes compared to standard IOS or IOS XE virtual images: Virtual Resource Minimum Specification Recommended Specification 1 to 2 vCPUs 4 vCPUs (Ensures control plane stability) RAM Allocation 12 GB to 16 GB per virtual node Hypervisor Mode QEMU x86_64 QEMU x86_64 with KVM acceleration enabled Disk Format QCOW2 running on Solid State Drives (SSD/NVMe)
Represents Cisco IOS XR Virtual . IOS XR is Cisco's flagship, modular, microkernel-based operating system designed for massive service provider networks, core routers, and edge platforms.
| Component | Meaning | |----------------|-------------------------------------------------------------------------| | iosxrv | Cisco IOS XR Virtual | | k9 | Strong encryption feature set | | demo | Trial version with throughput/feature limits | | 613 | Version 6.1.3 (legacy) | | qcow2 | QEMU disk format | | exclusive | Locking mode (prevent concurrent writes, used in GNS3/EVE-NG) | iosxrvk9demo613qcow2 exclusive
The QCOW2 filename must be renamed to hda.qcow2 inside this directory for the EVE-NG QEMU wrapper to launch it correctly. 3. Native QEMU / KVM
This command takes a VMDK (VMware) disk and converts it into a QCOW2 disk, renaming it to hda.qcow2 as required by many emulators.
Create a destination folder under the correct naming convention: mkdir -p /opt/unetlab/addons/qemu/iosxrv9k-6.1.3/

This specific "demo" image represents a 32-bit QNX-microkernel version, which is distinct from the 64-bit IOS XRv 9000, but still offers a robust feature set for learning and testing MPLS, BGP, and advanced routing protocols. Key Characteristics: 6.1.3 (Highly stable 6.x release). Format: QCOW2 (Native for KVM/EVE-NG/QEMU).
A minimum of 1 vCPU is required, though 2 vCPUs are recommended for faster boot times.
