Upload the image using an SFTP client (like WinSCP) to that directory.
D. OSPF adjacency (area 0)
To use this image, you must have a QEMU-compatible hypervisor, typically managed through or EVE-NG . 1. Requirements for Running 6.1.3 RAM: At least 3072 MB (3GB) per router is recommended. CPU: Multiple vCPUs required (2 vCPUs minimum).
You can easily spin this up in EVE-NG. Configure ISIS Level-2 only on core links, enable MPLS globally, and establish LDP or SR. Iosxrv-k9-demo-6.1.3.qcow2
At its core, iosxrv-k9-demo-6.1.3.qcow2 is a pre-installed disk image file for the . The "XRv" stands for "IOS XR virtualized," and it is a virtual machine (VM) that runs the same Cisco IOS XR operating system found on Cisco's high-end carrier-grade routers. The qcow2 format (QEMU Copy-On-Write version 2) is a disk image format used by the KVM (Kernel-based Virtual Machine) hypervisor. As noted in Cisco’s installation guide: "The qcow2 disk image has an instance of the Cisco IOS XRv 9000 Router pre-installed". This means the image is ready to boot, reducing the setup time significantly.
image is a popular choice for building virtual labs because it provides a functional version of Cisco's IOS XR software in a lightweight, QEMU-compatible format. What is the IOS XRv Demo Image?
When you first power on the virtual machine, be patient. IOS XRv boots an underlying Linux kernel first, followed by the IOS XR infrastructure, which can take between 3 to 7 minutes depending on your CPU speed. Setting Up Root Credentials Upload the image using an SFTP client (like
Cisco IOS XRv is significantly heavier than standard IOS (IOSv). To run version 6.1.3 smoothly, your host machine should meet these minimums: 3072 MB (3 GB) per instance. vCPUs: At least 1. Disk Format: QCOW2 (Optimized for QEMU/KVM). How to Install in Your Lab
When you fire up Iosxrv-k9-demo-6.1.3.qcow2 in a hypervisor (like KVM/QEMU), the file acts as a "base image."
hypervisor environment and is widely used with network emulation platforms: : Users often create a specific directory (e.g., /opt/unetlab/addons/qemu/xrv-k9-6.1.3 ) and rename the file to to make it compatible with the GNS3 registry You can easily spin this up in EVE-NG

The qcow2 format is compatible with KVM/QEMU environments but is not native to VMware products. This was a common task for engineers using the image.
