The filename follows Fortinet’s structured naming convention. Let’s decode it piece by piece.
| Segment | Meaning |
|---------|---------|
| fgt | FortiGate product |
| vm64 | Virtual Machine, 64-bit architecture |
| kvm | Target hypervisor: Kernel-based Virtual Machine (Linux KVM) |
| v7.2.1 | Major version 7, minor version 2, patch release 1 |
| f | Fortinet’s internal build label (often for “feature” or “full”) |
| build1254 | Internal build number (1254) – specific code revision |
| fortinet.out | Outbound/standard release (not a debug build) |
| kvm.qcow2 | Disk format: QEMU Copy-On-Write version 2 |
Key takeaway: This image is a production-ready FortiGate VM firmware version 7.2.1, build 1254, intended for KVM-based virtualization platforms.

This firmware image, fgt-vm64-kvm-v7.2.1.f-build1254-fortinet.out.kvm.qcow2 , is the official deployment file for FortiOS 7.2.1 KVM hypervisor
. Released around August 2022, this version is widely used in network simulations like and lab environments. Key Performance & Stability Reviews Virtual Performance:
note that while the VM works well, it lacks ASIC acceleration found in hardware. To reach speeds of 1GbE or higher, you must optimize KVM using License Limitations: Version 7.2.1 introduced a permanent trial license
with restricted features (e.g., max 1 CPU, 2GB RAM, and no HTTPS admin access). In simulations, users often encounter NTP-related license validation issues if the host and VM times are out of sync. Known Issues: GUI Display:
Certain FQDN address lists may show incorrect errors in the GUI, even if they resolve correctly in the backend. Proxy Stability:
Build 1254 may experience delays in loading explicit proxy policy lists. Vulnerability Alerts: Security advisories such as CVE-2024-3596 qemu-img info fgt-vm64-kvm-v7
(RADIUS vulnerability) affect versions in the 7.2 family; administrators are advised to eventually upgrade to FortiOS 7.2.11 for long-term stability.

This post refers to the FortiGate-VM64 for KVM (Version 7.2.1, Build 1254) virtual appliance. This specific .qcow2 image is used to deploy a virtual Next-Generation Firewall (NGFW) on Linux-based hypervisors like KVM, QEMU, GNS3, or EVE-NG. Deployment Overview
Filename: fgt-vm64-kvm-v7.2.1.f-build1254-fortinet.out.kvm.qcow2 Version/Build: v7.2.1 build 1254. Hypervisor: KVM (Kernel-based Virtual Machine).
Default Credentials: 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
Security best practice dictates keeping FortiOS updated. Assuming you need to go to v7.2.10 (a hypothetical later patch):
Alternative (for snapshots): Since you have a qcow2 file, you can take a snapshot before the upgrade:
virsh snapshot-create-as fortigate-721 pre-upgrade --disk-only --atomic
If the upgrade fails, revert instantly: virsh snapshot-revert fortigate-721 pre-upgrade Example output:
image: fgt-vm64-kvm-v7
The .qcow2 format is not native to VMWare. You must convert it to .vmdk.
The Transmutation Ritual (Command Line):
You will need qemu-img installed (available on most Linux distros or via Homebrew on Mac).
qemu-img convert -f qcow2 -O vmdk fgt-vm64-kvm-v7.2.1.f-build1254-fortinet.out.kvm.qcow2 fortigate.vmdk
Use the resulting .vmdk file as your boot drive in VMWare.
