Despite being an older release, version 5.2.2 contains the fundamental core technologies utilized in modern Service Provider environments. Core Routing Protocols iosxrv-k9-demo-5.2.2.ova
By default, the first network interface (NIC 1) maps to the Management Ethernet interface of the router. Subsequent NICs map to GigabitEthernet data ports. Map NIC 1 to a host-only or bridged network to access it via SSH from your local machine. Power On: Start the VM and open the virtual console. Initial Boot and Configuration

It is important to note that the older 32-bit architecture found in 5.2.2 is distinct from modern versions of IOS XRv (often called IOS XRv 64-Bit or evolution/eXR), which began with the 6.0 releases. Modern variants are built on a 64-bit Linux kernel, offer better containers support, and support API-driven programmability (like gRPC and advanced YANG models).
| Issue | Likely Cause | Solution | | :--- | :--- | :--- | | | Insufficient RAM allocated to the VM. The IOS XR control plane is memory-intensive. | Ensure you have allocated at least 3 GB (3072 MB) of RAM to the VM as per the requirements. | | Interface is up/up but no traffic passes. | The interface is configured in the VM but not correctly enabled in IOS XR. | In IOS XR, you must enter interface configuration mode (e.g., configure terminal , interface GigabitEthernet0/0/0/0 ) and issue the no shutdown command. | | Cannot connect to the router's management interface (e.g., via SSH/Telnet). | The ssh and telnet services are not enabled by default in IOS XR. | SSH: You need to generate RSA keys ( crypto key generate rsa ) and configure the VTY lines. Telnet: Enable the telnet server ( telnet vrf default ipv4 server enable ). | | Demo image is outdated or has a known bug. | Cisco's older IOS XRv demo images have known limitations and bugs, with some users reporting specific issues with version 5.2.2, such as a service-policy command not working as expected. | For the latest features and bug fixes, consider using a newer image. However, be aware that Cisco is focusing on the XRv 9000 series for its virtualization needs, and the "classic" IOS XRv has been deprecated. | Core Routing Protocols By default, the first network
Without a license, the Cisco IOS XRv 9000 Router is rate-limited to , making it useful for basic control plane learning but not for data plane performance testing. Production images require a license, while the demo image is specifically for evaluation and learning. To deploy a production image in simulation mode, supported hypervisors are VMWare ESXi 5.0 or later, or QEMU 1.0.
