Then create a new VM in VMware and attach the converted VMDK file as the hard disk.

For legitimate learning, use official Cisco IOS XRv images with proper versioning, such as iosxrv-x64-7.3.2.qcow2 or iosxrv-fullk9-x-7.5.1.qcow2 . These will save you from mysterious crashes, licensing quirks, and security risks.

: If starting with an .ova or .vmdk file, it can be converted to .qcow2 for use in KVM-based hypervisors. iosxrvk9demo613qcow2

Because IOS XR is a modular microkernel operating system (running over a QNX or Linux base), the first time you boot the image, it initializes multiple sub-systems and compiles initial internal configurations. This process can take anywhere from 5 to 10 minutes depending on your underlying CPU speed. Do not panic and reboot the node if it appears hung at the loading prompt; give it time to fully initialize.

More broadly, such filenames reflect a profound shift in networking. Where once one needed a rack of physical routers (costing thousands of dollars, consuming power and space), now a single laptop can run multiple virtual routers, switches, and firewalls. This accessibility lowers the barrier to entry for aspiring network engineers and enables rapid prototyping. It also aligns with the rise of “Network as Code,” where virtual images are versioned, stored in registries, and spun up via automation tools like Vagrant or Ansible. Then create a new VM in VMware and

The CPU flags must include the sse4_2 flag to support the embedded dataplane that processes network traffic. If your host CPU lacks this instruction set extension (e.g., very old AMD or Intel processors), the router may not boot or will run with severely degraded performance.
