Demystifying fortios.qcow2: The Backbone of Virtual Security Labs

If you have ever tried to set up a virtual network lab or deploy a firewall in a Linux-based cloud environment, you’ve likely encountered the fortios.qcow2 file. This specific file format is the gateway to running Fortinet's industry-leading FortiOS as a Virtual Machine (VM). fortios.qcow2

Whether you are a network engineer building a proof-of-concept in GNS3 or an architect deploying to KVM, understanding this file is critical to your success. What exactly is fortios.qcow2?

The .qcow2 (QEMU Copy-On-Write) format is a disk image file used by the KVM (Kernel-based Virtual Machine) hypervisor. Unlike a physical appliance that comes as a box of hardware, fortios.qcow2 contains the entire operating system and file structure of a FortiGate firewall in a single, compact virtual disk.

FortiOS 8.0 with many innovations across the Security Fabric | Fortinet

This guide provides instructions for using the fortios.qcow2 file, which is the virtual disk image used to deploy Fortinet FortiOS (FortiGate) as a Virtual Machine. Do not use random

This image is primarily used with KVM/QEMU hypervisors (like Proxmox VE, Red Hat Virtualization, or local Linux KVM) but can also be converted for other platforms.

If you are running a standard Linux server with KVM/libvirt, use virt-install or virsh.

Option A: Quick Launch (virt-install)

virt-install \
  --name FortiGate-VM \
  --ram 2048 \
  --vcpus=2 \
  --import \
  --disk path=/path/to/fortios.qcow2,format=qcow2,bus=virtio \
  --network bridge=virbr0,model=virtio \
  --graphics none \
  --console pty,target_type=serial

Option B: Using virsh

---

After deployment, access the console via virsh console fortigate-prod or via the VNC/telnet port. The default credentials:

FortiOS will boot, detect virtio interfaces, and assign port1, port2, etc. You must assign IP addresses:

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

Then access the GUI: https://192.168.1.99 (accept self-signed certificate).
