How to Convert a Cisco BIN File to QCOW2 for GNS3 and EVE-NG
Converting a Cisco IOS-XE .bin (e.g., csr1000v-universalk9.16.12.04.bin ) into a bootable qcow2 disk for KVM. convert cisco bin to qcow2
The first step is to prepare the Cisco BIN file for conversion. You will need to extract the file's contents, which are typically compressed and encrypted.
This will extract the contents of the BIN file to a directory named _extractor .
Here’s how to get started:
Converting a Cisco .bin to .qcow2 is not always straightforward because the .bin is often a firmware archive, not a disk image. The key steps are:
A valid .bin file (e.g., c7200-adventerprisek9-mz.152-4.M1.bin ). To install the necessary tools on Ubuntu/Debian, run: sudo apt-get update sudo apt-get install qemu-utils Use code with caution. Step-by-Step Conversion Process 1. Extracting the Image (If Necessary)
If you are working with or ASAv , you might need to convert a disk image: Ubuntu, Debian, or CentOS (native or via WSL2)
qemu-img convert -f vmdk source_image.vmdk -O qcow2 destination_image.qcow2 Use code with caution. 4. The "Manual" Wrap for Physical BINs
binwalk cisco-image.bin
The confusion arises because . Products like ASAv (Adaptive Security Virtual Appliance), CSR1000v, and IOSvL2 are officially provided as QCOW2 images by Cisco, usually after downloading a .zip or .tar archive that contains the disk image. Users who have seen those files sometimes assume they can take any Cisco .bin and “convert” it, which is generally not the case. You will need to extract the file's contents,
This step requires a (e.g., Alpine Linux or Ubuntu Live) to partition and install a bootloader on the qcow2 disk.
