Familiarizing oneself with the two-stage configuration ( commit / rollback ).
Move and rename the image to EVE-NG's standardized file format ( hda.qcow2 ):
If you obtained iosxrvk9demo613qcow2 from a non-Cisco source:
The updated iosxrv-k9-demo-6.1.3.qcow2 image solves long-standing bugs that hampered emulations: 1. Hypervisor Compatibility Patches
Additionally, keep in mind that IOS XR virtual routers are resource-intensive. A single instance can require 8-12 GB of RAM and 4-8 vCPUs for stable operation, so plan your lab resources accordingly.
: Minimum 3072 MB (3GB) RAM is required for stable boot and CLI responsiveness.
: Next, use the virt-install command to create the VM. Below is a sample command that defines a VM named iosxrv-demo with appropriate settings:
This comprehensive guide breaks down the core architecture, technical specifications, and updated setup processes required to host this image smoothly across modern network simulation hypervisors. Understanding the Technical Metadata
Even in 2026, IOS-XR 6.1.3 provides a robust feature set for simulation:
