This article provides a comprehensive overview of this specific image, its key features, deployment methodologies on KVM, and best practices.
The keyword refers to a specific virtual machine (VM) image for the FortiGate Next-Generation Firewall (NGFW) . Specifically, this is a 64-bit image built for the Linux KVM (Kernel-based Virtual Machine) hypervisor, running FortiOS version 7.2.1 with build number 1254 .
Whether you are building a lab in GNS3 or deploying a production instance, here is what you need to know about this version. Understanding the Build : KVM (Kernel-based Virtual Machine) OS Version : FortiOS 7.2.1 (Build 1254)

Deployment notes (practical, prescriptive)
Assumptions: You have an Ubuntu 22.04/24.04 or RHEL 9 host with libvirt and virt-manager installed.
virt-install --name FortiGate-VM \ --memory 2048 --vcpus 2 \ --import --disk path=/path/to/fgt-vm64-kvm-v7.2.1.f-build1254-fortinet.out.kvm.qcow2 \ --network bridge=virbr0 --network bridge=virbr1 \ --os-variant generic --graphics vnc Use code with caution.

: The precise compilation build number assigned by Fortinet engineering.
On the host:
Username admin and no password (you will be prompted to set one upon first login). Step-by-Step Installation (virt-manager) For a standard KVM deployment using the Fortinet KVM Guide : Deploying the FortiGate-VM - Fortinet Document Library Whether you are building a lab in GNS3
Supports a minimum of 1 and up to several virtual interfaces. Features in FortiOS 7.2.1 (Build 1254)
: If you manage your firewall via FortiManager, ensure the FGFM protocol can communicate over TCP port 541 .
Login credentials (default):
Once the VM boots successfully, access the virtual console via virsh console or your GUI VNC viewer (such as Virt-Manager).
We will use virt-install (command line) and also mention virt-manager for GUI users. The image name is long – it’s a good practice to rename it to something simpler like fortios721.qcow2 after verifying its checksum.
