The first boot requires you to set the admin user password.
You will see a Linux kernel boot sequence (it is based on Linux). Do not interrupt it. You will eventually see a prompt asking you to press Enter.
The .qcow2 file wasn't just a disk image; it was a "ghost" of the physical giant that just died. Elias fired up the virtualization server. He didn't need the heavy metal right now; he needed the brain. He imported the image into GNS3 , the virtual lab environment that would serve as the router's temporary home. iosxrvk9demo613qcow2
: Represents the software version, in this case, Cisco IOS XR Release 6.1.3 .
IOS XR is modular and takes time to boot—be patient, it can take 5–10 minutes to reach a login prompt. The first boot requires you to set the admin user password
The iosxrvk9demo613qcow2 file can be deployed on several virtualization platforms. This section covers the most common approaches.
: Compatible with QEMU/KVM environments and commonly used in network emulation tools like GNS3 , EVE-NG , and Cisco Modeling Labs (CML) . Common Deployment Scenarios You will eventually see a prompt asking you to press Enter
: Support for BGP, OSPF, ISIS, and MPLS configurations.
Implies that the image is built for simulation environments. The throughput on the virtual data plane is artificially rate-limited, meaning you can test control-plane routing protocols (BGP, OSPF, IS-IS) but cannot run production internet bandwidth through it. 6.1.3: The release version of the IOS XR software train.
