: Do not attempt to run this image on a production router or on hardware without virtualization support – it is strictly a software‑only demo.
| Issue | Likely Cause | Solution | |-------|--------------|----------| | VM fails to boot (“No bootable device”) | The image is corrupted or not in qcow2 format. | Re‑download the image and verify its checksum. Use qemu-img info iosxrvk9demo613qcow2 to confirm format. | | Login prompt never appears | Serial console misconfiguration. | Ensure --console pty,target_type=serial is used. Alternatively, connect via VNC. | | License expires after 60 days | Demo image limitation. | Re‑deploy from a fresh copy of the image (snapshots do not reset the timer). | | Interfaces do not come up | Missing virtio drivers or wrong model. | In virt‑install, add model=virtio to the network definition. For older images, use model=e1000 . | | High CPU usage inside VM | IOS XR data plane runs in software. | Reduce routing protocols, disable unnecessary features, or allocate more vCPUs. |
| Action | Command | | :--- | :--- | | Enter Config Mode | configure terminal | | Show Interfaces | show interface brief | | Show IP Route | show route | | Show Version | show version | | Save Configuration | commit (saves running to startup automatically) | | Exit Config Mode | end |
The image is perfectly suited for Vagrant – there are public boxes like iosxr/6.1.3 that reference this exact file. Create a Vagrantfile : iosxrvk9demo613qcow2
The file is a virtual disk image that packages the Cisco IOS XRv operating system for virtualized environments. Built on the QEMU Copy-on-Write (QCOW2) format, this 64-bit software demo enables network engineers to test and validate Service Provider routing architectures within simulation platforms like GNS3 , EVE-NG , and Cisco Modeling Labs (CML). Key Technical Attributes
The iosxrvk9demo613qcow2 file serves as a powerful key to unlocking a professional-grade network engineering lab environment. By following these step-by-step guides, you can quickly move from a QCOW2 image to a fully functional virtual router, ready to help you master the intricacies of carrier-grade networking.
For legitimate access, Cisco provides the IOS XRv 9000 image to customers with valid service contracts through the Software Download portal. For evaluation, Cisco DevNet Sandboxes offer free, cloud-based labs with pre-deployed IOS XR devices, bypassing the need for local downloads entirely. : Do not attempt to run this image
Example snippet:
| Part | Meaning | |------|---------| | iosxrv | Cisco IOS XRv (virtual version of ASR 9000 series) | | k9 | Indicates cryptographic (encryption) support – typical for export-controlled versions | | demo | Likely indicates a demo, evaluation, or trial image | | 613 | Possibly a build number, date stamp, or arbitrary lab identifier | | qcow2 | QEMU Copy-On-Write version 2 – a disk format used by KVM, Proxmox, and other open-source hypervisors |
Log in to your EVE-NG server via SSH and run: mkdir -p /opt/unetlab/addons/qemu/iol-xr-6.1.3/ Use code with caution. Use qemu-img info iosxrvk9demo613qcow2 to confirm format
The market offers several virtual routing images, including Cisco’s IOSv, IOS XRv9000, and CSR1000v, as well as competitor solutions like Juniper vMX or Nokia VSR. So why specifically choose ?
Although is a “demo” image, it can handle a respectable load for learning purposes:
router, a platform used by network engineers to simulate Cisco's service-provider-grade operating system in virtual labs.
While this image is an excellent tool for training and general topology verification, it is critical to note its boundaries:
