Document Version: 1.0 Applicable Products: Cisco IOS-XE, Cisco vManage, Cisco ISRv (KVM), Cisco Cloud Services Router (CSR) Purpose: This document provides a standard operating procedure (SOP) for converting a raw binary ( .bin ) software image into a deployable package ( .pkg ) format. 1. Introduction Cisco distributes operating system images primarily as .bin files (e.g., isrv-universalk9.16.12.03.bin ). However, certain deployment platforms—particularly those utilizing application hosting, Cisco vManage software upgrades, or KVM-based virtualized environments—require a .pkg (Package) format. The .pkg format includes additional metadata and a structured filesystem that the hypervisor or orchestrator can validate and unpack. 2. Prerequisites Before conversion, ensure the following:
# Repackage as tar (Cisco PKG = tarball with specific naming) tar -czf isrv-universalk9.16.12.03.pkg -C pkg_root . For supported platforms, Cisco provides a closed-source tool:
