The "serial" designation indicates this image is pre-configured to use serial console access

Run the following command via SSH: /opt/unetlab/wrappers/unl_wrapper -a fixpermissions

This version is often used as a starting point for those learning Cisco SD-WAN (Viptela) integration. Csr1000v-ucmk9.16.12.1b-serial.qcow2 REPACK

Access your EVE-NG CLI and create a folder named csr1000v-16.12.1b .

The simplest repack operation uses qemu-img convert : Running multiple CSR 1000V nodes can be resource-intensive

Keep snapshots and backups

Advanced users can mount the QCOW2 image on a Linux host and modify its contents: Csr1000v-ucmk9.16.12.1b-serial.qcow2 REPACK

This signifies that the console output is pre-configured for a serial port rather than a VGA/Video output, which is the standard for headless server environments and network simulation tools.

Running multiple CSR 1000V nodes can be resource-intensive.
