Convert Cisco — Bin To Qcow2 [portable]

Guide — Convert Cisco BIN (IOS/IOS-XE) to QCOW2

This guide shows a straightforward, reproducible method to convert a Cisco IOS/IOS-XE image in BIN format (or OVA/VM images that contain BIN/IMG) to a QCOW2 disk image suitable for QEMU/KVM. Assumptions: you have a BIN or disk image file (e.g., iosxe.bin, csr1000v-universalk9.16.09.03.SPA.bin) or a Cisco virtual appliance packaged in OVA/VDI that contains a disk image. Commands shown use a Linux host (Debian/Ubuntu/CentOS) and require root or sudo.

Verify the file. It should now be much larger than the original .bin. 3. Converting Virtual Disk Formats (VMDK to QCOW2) convert cisco bin to qcow2

This boots immediately with no conversion needed. Guide — Convert Cisco BIN (IOS/IOS-XE) to QCOW2

Inside helper VM:

• Use extracted rootfs to create a new empty QCOW2 and install a hypervisor-bootable layout (advanced). Typical approach is to create an empty QCOW2, partition, format, and copy files with guestfish or mount loop devices.

While you cannot "convert" a raw firmware binary directly into a disk image using a single command, you can wrap it into a bootable QEMU image using these steps: Use extracted rootfs to create a new empty

Final Conversion: Use the QEMU disk image utility to change the raw output into a .qcow2 format:
