If the output indicates it is a POSIX tar archive or a zip archive, extract it:
Save as cisco2qcow2.sh :
Create a properly named directory under /opt/unetlab/addons/qemu/ . (e.g., mkdir /opt/unetlab/addons/qemu/csr1000vng-16.12.05/ ). Upload your cisco_ios_xe.qcow2 file to this directory. convert cisco bin to qcow2
For maximum control, you can run your Cisco images natively on a KVM hypervisor. This is the gold standard for high-performance virtual labs.
:
Cause: The source binary file is corrupted or protected by digital signatures that prevent raw translation.
Cisco .bin files are self-extracting zip archives. You can use standard decompression utilities to extract the raw executable image. On a Linux or macOS terminal, use unzip : If the output indicates it is a POSIX
Run directly via Dynamips emulation or require extraction.
Checklist (quick)
Fix: Ensure you are using Cisco "vIOS", "CSR1000v", or "ASAv" source files. Physical router binaries (e.g., ISR 4331 or Catalyst 9000 switches) cannot boot inside QEMU without an underlying target hardware ASIC architecture emulation layer. To help pinpoint any issues with your setup, tell me:
