Since the demo-locked image has hard-coded credentials ( lab/lab , cisco/cisco , root/root , admin/admin ), it is that these virtual machines are never deployed on an untrusted network, such as the public internet .
This article provides an exclusive breakdown of what this file is, its architecture, its deployment requirements, and how to utilize it effectively in modern network simulators.
A common mistake is overprovisioning resources on the hypervisor. One user reported that while the FAQ lists resource requirements for the IOS-XRv 9000 as 4 cores and 20GB per node, attempting to allocate less than that (e.g., 6 cores and 32GB for two nodes) caused the console to freeze. Correcting the resource allocation to meet the minimum requirements resolved the issue.
: Inside the directory, EVE-NG requires the primary disk file to be named virtioa.qcow2 : mv iosxrvk9demo613qcow2 virtioa.qcow2 Use code with caution.
The prefix iosxrv refers to the IOS-XR Virtual platform, Cisco’s carrier-grade operating system stripped of its hardware dependencies and packaged for x86 architectures. The segment k9 is a standard Cisco designator indicating the inclusion of strong cryptography and security features—essential for realistic simulations involving Secure Shell (SSH), IPsec, and other encrypted control planes. The term demo signifies the licensing model; this is not a production-ready image intended for revenue-generating traffic, but rather a time-limited or feature-restricted version designated for lab experimentation and proof-of-concept testing.
Before deploying configuration changes in a production environment, engineers use this image to validate complex QoS, traffic engineering, or BGP scenarios. Technical Specifications and Requirements
: Architecting operational Layer 3 VPNs, Layer 2 VPNs (VPLS/VPWS), and complex traffic engineering path rules.

Open the EVE-NG GUI, add a new node, select Cisco IOS XRv, and set the image to the one you just created. Key Scenarios for Using This Image
The primary challenge of working with the IOS XRv 9000 architecture compared to classic IOS (or even IOS XE/vIOS) is its . Because the real-world OS manages line cards and route processors independently, the virtual counterpart requires significant server overhead.
: Testing model-driven programmatic extraction of router statistics via gRPC or NETCONF/YANG rather than legacy, resource-heavy SNMP polling. Hardware Requirements & Performance Tuning
I. Introduction
Processor with virtualization support (Intel VT-x or AMD-V) is essential.
