Whether you are a seasoned network architect or a training enthusiast aiming for certification, mastering this image is essential for building realistic, scalable, and cost-effective virtual networking labs.
: The demo image runs the 64-bit IOS XR software stack. It is crucial to pass the sse4_2 CPU flag to the VM; otherwise, the Embedded Dataplane will fail to operate correctly.
Create the target directory within the QEMU repository using the naming scheme: /opt/unetlab/addons/qemu/xrv-k9-6.1.3/ .
To understand the story, you have to understand the filename. is a virtual version of Cisco’s IOS XR operating system, which runs on high-end carrier-grade routers (like the CRS and ASR 9000 series). iosxrvk9demo613qcow2 updated
: This image was widely used in lab environments like GNS3 and EVE-NG because it offered a 32-bit demo platform that required relatively low resources (about 3GB of RAM) compared to its heavy-duty physical counterparts.
: The standard QEMU Copy-On-Write 2 disk image format optimized for Linux KVM virtualization backends. Key Reasons Behind the 6.1.3 Update Focus
The iosxrv-k9-demo-6.1.3.qcow2 image is a 32-bit VM based on the QNX microkernel. It provides a single Route Processor (RP) with control plane and management plane capabilities. Whether you are a seasoned network architect or
mv /opt/unetlab/addons/qemu/xrv-k9-6.1.3/iosxrv-k9-demo-6.1.3.qcow2 /opt/unetlab/addons/qemu/xrv-k9-6.1.3/hda.qcow2 Use code with caution.
Establish an SSH connection to your EVE-NG server using an SFTP manager like WinSCP.
The iosxrvk9-demo.6.1.3.qcow2 file is a virtual disk image that runs the 32-bit Cisco IOS XR software . It is designed for demonstration and educational purposes, offering a "demo" capability that allows the image to run without requiring a permanent license file, which is ideal for EVE-NG users looking for rapid deployment. 6.1.3 Architecture: 32-bit (x86) Create the target directory within the QEMU repository
The updated version often mitigates common boot errors ( Kernel Panic ) experienced in the initial 6.1.3 release when run on newer QEMU versions within EVE-NG. Key Features of IOS-XR 6.1.3
: To run this updated image smoothly in a virtual lab, you generally need: : 1–2 cores. : 3GB to 4GB (minimum) per instance. : Usually around 1GB for the file itself. Key Use Cases Certification Prep : It is a staple for those studying for the CCNP Service Provider CCIE Service Provider exams, as it mirrors the CLI of physical ASR 9000 routers. Automation Testing
The "QEMU Copy On Write" disk format, used primarily by QEMU/KVM.
