Troubleshoot Fortigate in GNS3 on Mac
Budget: ₹600 – ₹601 INR
Fortigate Firewall has been imported into my local GNS3 installation on macOS, but the moment I try to power it on the console reports that KVM must be disabled. I followed the usual advice—edited gns3_server.conf and added enable_kvm = false under the [Qemu] section—restarted GNS3, yet the VM still refuses to boot.
I have only used GNS3 a few times, so I’m probably overlooking a detail such as the correct Qemu binary, extra command-line flags, or even an architecture mismatch. What I’d like is a concise, step-by-step fix (screenshare or a clearly written guide is fine) that gets the Fortigate Firewall running inside GNS3 on my Mac.
Deliverables and acceptance:
• Fortigate VM starts successfully in GNS3 and reaches the CLI login prompt.
• A short set of reproducible steps or config snippets showing exactly what was changed (paths, Qemu settings, additional packages, etc.), so I can spin up new labs myself afterward.
You can assume I already have GNS3 installed and the Fortigate qcow2 image on-hand; everything else is fair game—Terminal tweaks, Homebrew packages, alternative Qemu versions, or any other workaround you deem necessary.
Error Message:
KVM acceleration cannot be used (/dev/kvm doesn't exist). It is possible to turn off KVM support in the gns3_server.conf by adding enable_kvm = false to the [Qemu] section.
