: For older hardware images (like Cisco 7200), GNS3 can boot files directly using the Dynamips emulator without needing a conversion to Virtual Disk Conversion : If you have a different virtual disk format (like ), you can convert it using the convert cisco bin to qcow2
In practice, for most Cisco firmware images, this attempt fails with an error like:
The most reliable way to obtain a QCOW2 image for Cisco devices is to use the official virtual images provided by Cisco through Cisco Modeling Labs (CML). Cisco builds these images specifically for x86 virtual platforms, natively packaged as QCOW2. Step 1: Download the CML Images Navigate to the portal. Search for Cisco Modeling Labs . Download the CML Refplat ISO or individual node images. ) disk image is not a standard or straightforward process
Secure the native .qcow2 files directly from the Cisco Software Central portal under the CML download section.
This creates a folder containing the kernel and the root filesystem. Step 1: Download the CML Images Navigate to the portal

If you have a legacy .bin you cannot replace:
virtioa.qcow2 : The standard naming convention used by EVE-NG for primary virtual disks. Method 2: Handling Legacy Cisco IOS (.bin) Images
If the .bin file is already a raw image file that can be read by QEMU, you can convert it directly. Use the qemu-img command:
