To deploy the FortiGate VM64 KVM v7.2.3 build 1262 (fortinet.out.kvm.qcow2), follow this streamlined guide for a standard KVM environment. 1. Preparation
Download & Extract: Ensure you have the fortios.qcow2 file extracted from the Fortinet Support deployment package. Resource Requirements:
RAM: At least 2048 MB (2 GB) is required for version 7.0 and above. CPUs: Typically 1 to 4 vCPUs.
Disk: While the system runs from the .qcow2 file, a second virtual disk (30 GB+) is highly recommended for logs. 2. VM Deployment (using virt-manager) Deploying the KVM qcow2 tar.gz file - HPE Support

Versions higher than 7.2.0 have a highly restrictive trial license, which may limit testing functionality compared to older versions. Common Commands for KVM
If you are importing this image manually on a Linux host, you can use the virt-install С-Терра: портал документации virt-install --name fortigate-vm --ram fgtvm64kvmv723fbuild1262fortinetoutkvmqcow2 new

The specific filename fgtvm64kvmv723fbuild1262fortinetoutkvmqcow2 refers to a FortiGate-VM image designed for KVM (Kernel-based Virtual Machine) environments, specifically version 7.2.3, build 1262 in .qcow2 format.
While there isn't a single narrative article written solely about this specific build, you can explore detailed technical guides and architectural breakdowns that explain how these KVM/QCOW2 images function and how to deploy them. Recommended Reading & Resources
Architectural Breakdown: To understand why Fortinet uses the .qcow2 format for KVM, the Technical Bulletin on KVM and QCOW2 provides an excellent look at how this disk format decouples the hypervisor from the storage layer, allowing for more flexible infrastructure management.
Performance & Risks: If you are deploying this for production, the article Understanding QCOW2 Risks with QEMU is essential. It discusses write semantics, metadata updates, and how to avoid data corruption during unplanned terminations—critical for a virtual firewall.
KVM Setup Guide: For practical steps on using a .qcow2 file like yours, the KVM Virtual Machine Creation Guide walks through the process of importing an existing virtual disk into a new VM instance using virt-manager.
Troubleshooting & Recovery: If you encounter issues where your image won't boot or seems the wrong size, community discussions on restoring KVM VMs from .qcow2 files offer practical "lessons learned" regarding XML definitions and hardware options. Why this Build Matters To deploy the FortiGate VM64 KVM v7
The v7.2.3 (Build 1262) release is a stable branch of FortiOS. Deploying it as a .qcow2 image on KVM allows you to:
Utilize Sparse Storage: The image only consumes the space it actually uses on the host.
Snapshot Support: You can take rapid snapshots for safe upgrades or configuration testing.
Cross-Platform Portability: This format is easily convertible to other types if you ever migrate away from KVM. Restoring a KVM VM from the .qcow2 file - Fedora Discussion
KVM is a Type-1 hypervisor built into the Linux kernel, offering:
Solution: Ensure the qcow2 image is not corrupted. Re-download and check the MD5/SHA256 checksum from Fortinet’s support portal. Also confirm it's a full image, not a backing file.
Use a regex to extract:
v723 → 7.2.3build1262 → 1262qcow2kvmExample (Python):
import re
s = "fgtvm64kvmv723fbuild1262fortinetoutkvmqcow2 new"
version = re.search(r'v(\d+)', s).group(1) # 723
build = re.search(r'build(\d+)', s).group(1) # 1262
qemu-img and custom XMLqemu-img create -f qcow2 -o backing_file=fortios.qcow2 fortigate-overlay.qcow2
# Then define domain via virt-manager or virsh define
Ensure interfaces use model type='virtio' (not e1000).
Check XML:
<interface type='bridge'>
<model type='virtio'/>
</interface>
Use virsh console fortigate-v723 or a VNC client to complete the initial setup. Default credentials are usually admin with no password (you will be forced to change it).
Before diving into deployment, let’s demystify the string piece by piece:
| Component | Interpretation |
|-----------|----------------|
| fgtvm64 | FortiGate Virtual Machine for 64-bit architecture |
| kvm | Hypervisor type – KVM (Linux native virtualization) |
| v723f | FortiOS version 7.2.3 (the ‘f’ may indicate a patch or specific branch) |
| build1262 | Internal build ID – specific compiled version |
| fortinet | Vendor – Fortinet Networks |
| outkvmqcow2 | Output format: KVM-compatible QCOW2 disk image |
| new | Indicates a recent release or updated artifact |
Thus, the full meaning is:
“FortiGate 64-bit VM for KVM, FortiOS 7.2.3 build 1262, provided as a QCOW2 image (new version).”
