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 : fgtvm64kvmv723fbuild1262fortinetoutkvmqcow2
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:
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.

It sounds like you’re working with a Fortinet FortiGate VM image — likely a qcow2 file — with a specific build tag (fgtvm64kvmv723fbuild1262fortinetoutkvmqcow2), probably for use in a KVM environment. it looks like random characters
Here are good features / capabilities you can highlight or leverage for this specific VM image:
In the world of enterprise cybersecurity, filenames and version strings often carry immense technical meaning. One such example is the seemingly cryptic string:
fgtvm64kvmv723fbuild1262fortinetoutkvmqcow2
At first glance, it looks like random characters, but to a network engineer or security architect, it tells a complete story: this is a FortiGate Virtual Machine (FGT VM), built for 64-bit KVM (Kernel-based Virtual Machine) hypervisors, running FortiOS version 7.2.3, with a specific build number (1262), and packaged as a QCow2 disk image.
In this article, we will unpack every segment of this identifier, explain the technology behind it, and discuss how such images are used in production and lab environments.
Service providers and large enterprises use KVM as a hypervisor for VNFs (Virtual Network Functions). This image can be integrated into an OpenStack environment with Heat templates or TOSCA orchestration.
Version 7.2.3 (build 1262) is a maintenance release from Fortinet. Key improvements over earlier 7.2.x:
