Use images instead.

Switching to isn't just a technical detail—it changes how you manage virtual lab storage.

Don’t let raw files eat your drive. Go qcow2. 💾

I see so many people downloading ISO files and installing OS's from scratch inside GNS3, or using massive raw .img files. Don't do that to yourself.

Convert any image: qemu-img convert -f raw -O qcow2 input.img output.qcow2

Fix it with qcow2 images. Save space. Use snapshots. Run more nodes.

Switch to : ✅ Saves SSD space (thin provisioning) ✅ Instant snapshots ✅ Better fork performance
