| Requirement | Description | |-------------|-------------| | | Valid Cisco IOS-XE or IOS-XR .bin file (e.g., from Cisco Software Download portal). | | Linux host | Ubuntu 20.04/22.04 or RHEL 8/9 with binwalk , unsquashfs , tar , and mksquashfs . | | Cisco PKG Tools | Custom Cisco tools or standard Linux packaging utilities (if Cisco toolchain unavailable). | | Disk space | Minimum 3x the size of the .bin file (e.g., 2GB .bin → 6GB free). | 3. Conversion Methodology 3.1. Manual Conversion (Using Open-Source Tools) If the Cisco-specific bin2pkg utility is unavailable, use the following manual extraction and repackaging process.

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: validate the .pkg file:

mkdir -p "$TMP_DIR/pkg/contents" cp -r "$FS_DIR/"* "$TMP_DIR/pkg/contents/" cat > "$TMP_DIR/pkg/metadata/package.ini" <<EOF [Package] Version = unknown Platform = generic Type = converted EOF

Create pkg_root/metadata/package.ini with:

TMP_DIR=$(mktemp -d) echo "Extracting $BIN_FILE..." binwalk -e "$BIN_FILE" -C "$TMP_DIR" >/dev/null 2>&1

Look for a squashfs or ext2 image. If found, mount it:

bin2pkg -i input.bin -o output.pkg --platform ISRv --version 16.12.03 This tool is typically embedded in Cisco NFVIS or vManage installations. Contact Cisco TAC for access if required for your contract. 4. Verification After conversion, validate the .pkg file:
