The following blog post outlines the process for deploying and configuring the FortiGate VM image (fgtvm64kvmv723fbuild1262fortinetoutkvmqcow2) on a KVM hypervisor. Deploying FortiGate v7.2.3 Build 1262 on KVM
Deploying a virtual firewall is a critical step in securing virtualized environments. The Fortinet FortiGate VM image, specifically the QCOW2 format designed for KVM, provides a flexible and powerful security gateway. This guide covers how to get Build 1262 up and running. Prerequisites
Hypervisor: KVM/QEMU installed on a Linux host (e.g., Ubuntu, CentOS, or Fedora). Management Tools: virt-manager (GUI) or virsh (CLI).
Image File: The specific fgtvm64kvmv723fbuild1262fortinetoutkvmqcow2 file downloaded from the Fortinet Support Portal. Step 1: Prepare the Environment
Before importing the image, ensure your virtual networks are configured. FortiGate typically requires at least two interfaces: one for the "External" (WAN) connection and one for the "Internal" (LAN) segment. You can verify your current network status using: sudo virsh net-list --all Use code with caution. Copied to clipboard Step 2: Import the QCOW2 Image
To begin the deployment, move your downloaded image to the default libvirt storage directory :
sudo mv fgtvm64kvmv723fbuild1262fortinetoutkvmqcow2 /var/lib/libvirt/images/fortigate.qcow2 Use code with caution. Copied to clipboard
Use virt-install to create the VM. Note that FortiGate v7.2.3 requires specific resources for optimal performance:
sudo virt-install --name FortiGate-VM \ --ram 2048 \ --vcpus 2 \ --os-variant generic \ --disk /var/lib/libvirt/images/fortigate.qcow2,bus=virtio \ --network bridge=virbr0,model=virtio \ --import Use code with caution. Copied to clipboard Step 3: Initial Configuration
Once the VM starts, access the console through virt-manager or virsh console. Login: Use the default username admin with no password.
Set Password: You will be prompted to create a new password immediately. Configure Management IP: fgtvm64kvmv723fbuild1262fortinetoutkvmqcow2
config system interface edit port1 set mode static set ip 192.168.1.99 255.255.255.0 set allowaccess ping https ssh next end Use code with caution. Copied to clipboard Performance Tips
VirtIO Drivers: Always use VirtIO for both disk and network interfaces to ensure the highest possible throughput .
CPU Pinning: For high-traffic environments, consider pinning virtual CPUs to physical cores to reduce latency.
Snapshots: Take advantage of the QCOW2 format's native snapshot capabilities before performing major firmware upgrades.
The string "fgtvm64kvmv723fbuild1262fortinetoutkvmqcow2" identifies a specific FortiGate VM
firmware image file. Breaking down the filename reveals its primary characteristics and intended environment: : Indicates a FortiGate Virtual Machine architectures. : Specifies that this image is built for the (Kernel-based Virtual Machine) hypervisor. : Denotes the firmware version suffix stands for
release, meaning this version includes new capabilities and enhancements rather than just bug fixes. : Identifies the specific compilation or build number fortinetout
: Standard naming convention for a Fortinet-packaged output image. : Confirming the format as a
(QEMU Copy-On-Write) disk image, which is the native format for KVM. FortiGate Virtual Appliances Data Sheet - Fortinet

This guide outlines the deployment of FortiOS version 7.2.3 build 1262 specifically for KVM (Kernel-based Virtual Machine) environments using the .qcow2 image format. 1. Image File Identification
The filename fgtvm64kvmv723fbuild1262fortinetoutkvmqcow2 follows Fortinet's standard naming convention: fgtvm64: FortiGate 64-bit Virtual Machine. kvm: Target hypervisor (KVM/QEMU). v723: FortiOS Version 7.2.3. build1262: Specific software build number.
fortinet.out.kvm.qcow2: The raw disk image file used for deployment. 2. Deployment Requirements
Before starting, ensure your KVM host meets the following minimums:
Memory: At least 1024 MB (2048 MB recommended for full features).
Storage: A primary disk (the .qcow2 file) and a secondary disk (typically 30 GB) for log storage.
Network: A minimum of one interface for management (Port1); FortiGate VMs typically support up to 10 or more. 3. Installation Steps (Standard KVM)
Download & Extract: Obtain the image from the Fortinet Support Portal and extract the .zip file to get the .qcow2 image.
Create New VM: Use virt-manager or virsh to create a new VM. Import Disk: Select Import existing disk image. Browse to the ...fortinet.out.kvm.qcow2 file.
Add Log Disk: Create and attach a second empty virtual disk (e.g., 30GB) to the VM. The FortiGate will automatically format this for logging upon boot.
Configure Network: Set network adapters to VirtIO for best performance. 4. Initial Configuration Once the VM boots: Login: Use the default username admin with no password.
Set Admin Password: The system will immediately prompt you to create a secure password. Configure Management IP (Example):
config system interface edit port1 set mode static set ip 192.168.1.99 255.255.255.0 set allowaccess http https ssh next end Use code with caution. Copied to clipboard
GUI Access: Navigate to https://192.168.1.99 in your browser to access the full management interface. 5. Licensing
Evaluation Mode: Newer versions like 7.2.3 allow for a limited evaluation license if you link the VM to a valid FortiCloud account. Which of these would you like next
Permanent License: Upload your .lic file through System > GUI > FortiGuard once connectivity is established.
