The goal: remove transient data (logs, old configs, SSH keys) without altering the serial/license file.

By sunrise, Leo had scripted it into a 12-line pipeline. Colleagues called it —clean, verifiable, and production-hardened.

This is the most critical step for saving space. It removes "zero blocks" from the virtual disk. : virt-sparsify --compress input.qcow2 output.qcow2 Result : Can shrink an 8GB image down to under 1GB. 3. Apply Compression The goal: remove transient data (logs, old configs,

While not strictly mandatory, running a filesystem defragmentation inside the CSR1000v can help group free space into contiguous blocks, making the subsequent zero‑fill more effective. In IOS XE, this is automatically performed by the disk’s internal management; for most repacking tasks, moving directly to the next step is sufficient.

: Choosing the right throughput tier during the repack (e.g., 10Mbps, 100Mbps, or 1Gbps) determines how the virtual CPU handles traffic. For a lab, the 10Mbps "free" tier is often chosen to minimize the licensing overhead while still testing complex BGP or OSPF configurations. The Virtual Frontier The (now evolving into the Cisco Catalyst 8000V

Once your repacked image is ready to boot, assigning the correct hardware flags within your hypervisor configuration determines how efficiently it will execute. For IOS-XE version 16.12.1b, apply these specific hardware mappings:
