Convert Cisco | Bin To Qcow2 [work]

For Cisco’s official virtual products like the CSR1000v router, vIOS switch, or ASAv firewall,

By following this process, you can easily convert Cisco virtual images into a format suitable for complex network simulations, allowing for flexible lab environments.

If you have a working Cisco VM image (like from CML/VIRL), you can simply convert that to qcow2:

qemu-system-x86_64 \ -machine pc \ -cpu host \ -m 4096 \ -drive file=cisco.qcow2,format=qcow2,if=virtio \ -net nic -net user \ -serial mon:stdio \ -nographic convert cisco bin to qcow2

The resulting QCOW2 file can be used in various virtualization environments, such as KVM or OpenStack, allowing you to virtualize a Cisco device on non-Cisco platforms.

If you want, I can help you by assisting with:

If you have a Cisco virtual appliance image in .vmdk format (common in VMware environments), use the qemu-img utility to convert it. Cisco Modeling Lab IOS Image convert

Here’s how to get started:

If your file is not already in .vmdk or .raw format, try extracting it using tar or unzip , though many .bin files are actually raw disk images. Verify the file type: Use the file command: file iosv.bin Use code with caution.

: Create a blank .qcow2 file that will serve as the "hard drive" for the virtual router. Example: qemu-img create -f qcow2 cisco_router.qcow2 1G

grub-install --target=i386-pc --boot-directory=/mnt/cisco/boot /dev/loop0

Before you open a command prompt, it is crucial to understand you are trying to convert. For Cisco’s official virtual products like the CSR1000v

This will extract the contents of the BIN file to a directory named _extractor .

Sometimes the simplest approach is the best.

— most Cisco .bin images are not Linux kernels . For IOS-XE in QEMU, you often need extracted kernel + rootfs. The generic “convert alone” is not bootable unless you have vmlinuz and rootfs separately.
