The most streamlined method for repacking uses the netlab tool, which was specifically designed to automate the creation of Vagrant boxes for network devices like the CSR1000v.
In DevOps and network engineering circles, the term "repack best" often refers to the practice of unpacking the QCOW2 image, modifying the filesystem (e.g., editing grub.cfg , injecting configuration scripts, or bypassing the "autoreboot" associated with licensing), and re-packaging the image for mass deployment. This paper evaluates the validity of these "best" practices.

to actually perform a QCOW2 repack, or are you looking for more involving virtual network labs?
However, the raw .qcow2 file from Cisco is often bloated, occupying significantly more space than necessary and potentially causing high CPU usage in virtualization platforms. "Repacking" this image using specialized techniques can shrink the size and improve performance. This article explains the . 1. Why Repack the CSR1000v Serial Image? The most streamlined method for repacking uses the
: Use an SFTP client like WinSCP or FileZilla to transfer the original csr1000v-ucmk9.16.12.1b-serial.qcow2 into that new folder.

Create a directory named exactly csr1000vng-16.12.01b inside /opt/unetlab/addons/qemu/ . Move your repacked file into that directory and rename it to virtioa.qcow2 .
