When the router finishes booting, you might be dropped into a UEFI shell or the IOS XR prompt.
To access the Console:
Setting up Management IP (MgmtEthernet0/0/CPU0/0): IOS XR requires you to explicitly configure the Management interface and enable SSH. iosxrvk9demo613qcow2 exclusive

Note on the "Demo" Limitation: Since this is a "Demo" image, you may encounter restrictions.
QCOW2 supports backing files and copy-on-write. If iosxrvk9demo613qcow2 is a base image, you typically create overlay (snapshot) images for each VM instance and lock the base image as exclusive read-only. However, if the base image is accidentally opened read-write by two VMs, corruption is almost certain. When the router finishes booting, you might be
Thus, hypervisor managers (libvirt, oVirt, OpenStack) use exclusive locks to enforce:

In the world of network virtualization and software-defined networking (SDN), engineers often encounter cryptic filenames and command-line outputs. One such string—iosxrvk9demo613qcow2 exclusive—contains critical information for anyone working with Cisco’s IOS XRv (Virtual Routing and Forwarding) platform.
This article breaks down what this string means, its components, and why the term exclusive matters when deploying virtual network devices. Note on the "Demo" Limitation: Since this is
qemu_options: -machine type=pc,accel=kvm -cpu host -smp 2 -m 4096 -drive file=iosxrvk9demo613.qcow2,if=virtio,exclusive
(Not standard syntax; EVE‑NG uses internal locking.)
