One specific feature introduced in FortiOS 7.2.3 (the version for that KVM build) is the support for FortiGate VM VDOM licenses.
Previously, VDOM (Virtual Domain) capacity was often tied to the VM's hardware resource limits or specific VM models. Starting with this release, you can add standalone VDOM licenses to your FortiGate VM to expand its multi-tenancy capabilities without necessarily upgrading the entire VM tier.
Other notable characteristics of this specific KVM/qcow2 deployment include:
vSPU Acceleration: This build utilizes DPDK and vNP offloading, which can more than triple UDP firewall throughput by bypassing the standard operating system kernel during packet processing.
SR-IOV Support: It allows the VM to talk directly to network adapters via Direct Memory Access (DMA), significantly reducing latency for "north-south" network traffic.
Strict Evaluation Limits: If you are using this build with a trial license, it is limited to 1 CPU and 2 GB of RAM.

build1262: The exact internal build number (1262) assigned by Fortinet engineers. fortinet: The vendor name.
out: Signifies this is the file meant for deployment/installation (output package).
kvm.qcow2: The actual file extension. QCOW2 (QEMU Copy-On-Write) is the native disk image format for QEMU/KVM. 🛠️ Key Technical Specifications
Before deploying this specific image, it is important to understand its resource requirements and environment compatibility. System Requirements Minimum CPU: 1 vCPU (2+ recommended for production).
Minimum RAM: 2 GB (4 GB+ recommended for enabling full security profiles).
Hard Drive: Typically requires a minimum of 30 GB to 40 GB for logs and system storage (usually added as a second virtual disk). Environment Compatibility
This image is designed to run on open-source and enterprise Linux virtualization stacks, including: Proxmox VE (Very popular for homelabs and SMBs). Ubuntu/Debian KVM managed via virt-manager or CLI. Red Hat Enterprise Linux (RHEL) / CentOS KVM.
EVE-NG and GNS3 (Network emulation platforms for testing and training). 🚀 Step-by-Step KVM Deployment Guide
Deploying this QCOW2 file generally follows a standard procedure across most KVM-based platforms. Step 1: Upload the Image
Transfer the fgtvm64kvmv723fbuild1262fortinetoutkvmqcow2 file to your hypervisor's storage directory (e.g., /var/lib/libvirt/images in standard Linux KVM or your local storage in Proxmox). Step 2: Create the Virtual Machine
Create a new VM instance with the following baseline settings: OS Type: Linux. CPU & RAM: Allocate at least 1 vCPU and 2GB RAM. fgtvm64kvmv723fbuild1262fortinetoutkvmqcow2 exclusive
Network Interfaces: Attach at least 2 network interfaces (one for WAN/Management and one for LAN). FortiGate VMs usually default to Port1 as the management interface. Step 3: Attach the QCOW2 Disk
Instead of creating a new blank disk, point the VM's primary storage to the uploaded Fortinet QCOW2 file.
Note for Proxmox users: You will often create a dummy VM and then use the CLI command qm importdisk to attach the Fortinet image properly. Step 4: Add the Log Disk (Crucial)
FortiGate requires a second hard drive to store system logs, reports, and WAN optimization data. Add a secondary virtual disk of at least 30 GB.
If you fail to do this, the FortiGate will constantly prompt you that a log disk is missing, and certain reporting features will be disabled. Step 5: Power On and Initial Config
Boot the virtual machine. Access the console to perform the initial setup:
Default Login: Username is admin. There is no password by default (press Enter).
Set New Password: The system will immediately force you to create a complex password. Configure Management IP:
config system interface edit port1 set mode static set ip 192.168.1.99 255.255.255.0 set allowaccess https ssh ping next end Use code with caution.
Once configured, you can access the full graphic user interface (GUI) by typing https://192.168.1.99 into your web browser. ⚠️ Important Considerations for FortiOS 7.2.3
If you are specifically looking for or deploying version 7.2.3 (Build 1262), keep the following in mind: Evaluation Limitations
If you are running this without a paid license (Evaluation Mode), Fortinet enforces strict limits: Low encryption standards only. Limited number of firewall policies. No access to live FortiGuard security updates.
Note: In newer FortiOS versions, evaluation accounts require a valid FortiCare account and an internet connection to activate. Upgrade Path
If you plan to upgrade this VM to a newer version of FortiOS in the future, do not jump straight to the latest version. Always consult the Fortinet Upgrade Path Tool on the Fortinet Support Portal to ensure you do not corrupt your configuration database.
