Thus, is a pre-configured, bootable virtual disk image containing a fully operational FortiGate virtual appliance. Unlike an ISO installer, which requires interactive setup, the .qcow2 file is a "golden image" designed for rapid, unattended deployment on KVM-based hypervisors (Proxmox, oVirt, Red Hat Virtualization, and pure libvirt environments).
This image is primarily used with hypervisors (like Proxmox VE, Red Hat Virtualization, or local Linux KVM) but can also be converted for other platforms.
This format is highly efficient for virtualization, supporting features like copy-on-write, snapshotting, and zlib-based compression to reduce storage footprint.
Extract the archive to locate the primary boot image file, usually named fortios.qcow2 . Step 2: Create a Secondary Log Disk
Allows administrators to take point-in-time states of the FortiOS file system before performing upgrades or major configuration changes. fortios.qcow2

Click on the tab and navigate to the specific FortiOS version branch you require (e.g., v7.0, v7.2, or v7.4).
Add a default route so the virtual appliance can reach the internet for licensing and database updates:
Virtualizing network security is a cornerstone of modern enterprise infrastructure. Fortinet's FortiGate Next-Generation Firewall (NGFW) is widely deployed in virtual environments using the virtual disk image. This file format allows administrators to run FortiOS as a virtual machine (VM) on open-source and enterprise hypervisors, streamlining lab testing, automated scaling, and cloud-edge deployments. What is Fortios.qcow2? Thus, is a pre-configured, bootable virtual disk image
The file name fortios.qcow2 represents the virtual disk image used to run FortiGate-VM on hypervisors that support the QEMU Copy-On-Write (QCOW2) format. Key Characteristics of QCOW2 for FortiOS
Toggle the switches for the features you want to "make" active (e.g., SD-WAN, Advanced Routing, Web Filter). Fortinet Document Library Step 2: Enable Features via CLI
When you download FortiOS in this format, you receive a pre-configured virtual disk file containing the FortiOS operating system. It features:
Using the fortios.qcow2 image provides . You can scale your security posture by increasing vCPU counts without swapping hardware. It also allows for snapshots , letting you save the state of your firewall before making risky configuration changes. Do you need help with automation for this image
From the first virt-install command to advanced SR-IOV tuning, the journey with fortios.qcow2 is one of flexibility, performance, and control. Fortinet has decoupled its industry-leading NGFW from proprietary hardware—and armed with this guide, you can deploy it anywhere Linux runs.
It is the primary file used in GNS3 , EVE-NG , and PNETLab to build complex network topologies without buying physical hardware.
Upload your QCOW2 image into this directory and rename it exactly to virtioa.qcow2 .
cp fortios.qcow2 /var/lib/libvirt/images/fortios.qcow2 cp fgt_system.qcow2 /var/lib/libvirt/images/fgt_system.qcow2 Use code with caution. 2. Execute the Installation Command
