Fgt Vm64 Kvm-v7.4.7.m-build2731-fortinet.out.kvm.qcow2 May 2026

The file FGT_VM64_KVM-v7.4.7.M-build2731-FORTINET.out.kvm.qcow2 is the official virtual appliance image for FortiGate VM64 running on KVM (Kernel-based Virtual Machine) for FortiOS version 7.4.7, released around January 21, 2025. This specific build, 2731, is a mature release in the 7.4 "Mature" (M) branch, often used for production stability or in-depth lab testing. 1. Key Technical Specifications Version: 7.4.7, Build 2731 (Mature release).

Platform: Linux KVM, compatible with hypervisors like Proxmox, EVE-NG, and GNS3.

File Format: .qcow2 (QEMU Copy-On-Write), typically around 95-103 MB compressed. Checksum (MD5): 2ce4039789e84b3fe85565e0c4110718. 2. Deployment in Lab Environments

Most "write-ups" for this specific file focus on getting it running in a home lab or simulation environment. EVE-NG Setup

Directory Creation: Use SSH to create a directory named fortinet-FGT-7.4.7-2731 under /opt/unetlab/addons/qemu/. fgt vm64 kvm-v7.4.7.m-build2731-fortinet.out.kvm.qcow2

Upload & Rename: Upload the .qcow2 file to that folder and rename it to virtioa.qcow2 for the hypervisor to recognize it as a boot disk.

Fix Permissions: Run the command /opt/unetlab/wrappers/unl_wrapper -a fixpermissions to ensure the VM can start. GNS3 Setup

Appliance Import: Use the FortiGate appliance template (.gns3a) from the GNS3 Marketplace.

Resources: Version 7.4+ generally requires at least 2GB of RAM and 2 vCPUs to avoid "conserve mode" (a state where features like antivirus are disabled to save memory). 3. Evaluation License Restrictions The file FGT_VM64_KVM-v7

If you are using this without a paid license, you will fall under the FortiOS Permanent Trial license: FortiGate - GNS3

RAM: A minimum of 2 GB is required for FortiOS 7.0 and higher.

CPU: Ensure your host CPU supports virtualization (Intel VT-x or AMD-V) and that it is enabled in the BIOS.

Trial Limitations: Recent FortiOS trial licenses (7.2.0 and above) are highly restrictive. Full functionality requires a valid license from the Fortinet Support Portal. Deployment Overview and Security Implications

This specific file is typically used for new installations rather than upgrades. Common deployment steps on a KVM host (like Ubuntu) include: FortiOS 7.6 KVM Administration Guide - AWS

5.2 Backup & Snapshot

QCOW2 snapshots: virsh snapshot-create-as
Memory snapshot may corrupt session table – recommend config-only backup

5.1 Licensing

BYOL (Bring Your Own License) – .lic file from Fortinet
Trial limitations (no HA, limited throughput)
VM UUID tied to license – must not change after clone

6. Basic Policies (Internet Access)

Minimal config:

config firewall policy
    edit 1
        set srcintf port2   # WAN
        set dstintf port1   # LAN
        set srcaddr all
        set dstaddr all
        set action accept
        set schedule always
        set service ALL
        set nat enable
    next
end

Troubleshooting checklist

VM won’t boot: inspect console via virsh console or the virtual machine’s VNC/serial output; verify disk paths and qemu-img info.
Network not reachable: check bridge configuration, interface model (virtio) compatibility, and ensure guest interfaces are up and have correct IPs.
High latency or throughput issues: check host CPU steal, I/O wait, and NIC offload settings; consider pinning vCPUs to physical cores.
Licensing issues: ensure FortiGate-VM has a valid license and appropriate virtual chassis or VM-only licensing per Fortinet documentation.
