Configure a default gateway route so the virtual appliance can reach the internet and FortiGuard licensing servers:
: Attach a blank, secondary QCOW2 disk (minimum 30GB) to the VM before booting. Issue 2: License Shows "Invalid" or "Evaluation Expired"
2 GB minimum (1 GB can be used for basic testing in lab environments, but features like GUI or logging might be restricted). fortios.qcow2
Look for the file designated for KVM deployment. This is typically delivered as a .zip archive named something like FGT_VM64_KVM-v7.x.x.F-buildXXXX.DIR.out.kvm.zip . Step 4: Extract the Archive
Network virtualization is a cornerstone of modern enterprise IT infrastructure. Fortinet, a global leader in cybersecurity, provides its flagship operating system, FortiOS, in various virtual machine formats to support this shift. For administrators working within Kernel-based Virtual Machine (KVM) environments, QEMU, or network simulation platforms like GNS3 and EVE-NG, the key file format you will encounter is . Configure a default gateway route so the virtual
The base fortios.qcow2 image acts as the primary boot disk (Drive A). FortiOS requires a second virtual disk (Drive B, typically 10 GB to 30 GB+) initialized as a log disk to function properly. Step-by-Step Deployment Guide (CLI via KVM/QEMU)
The free evaluation license has strict functional boundaries. FortiOS evaluation downloads often restrict cryptographic features, allow only low-strength encryption, limit resource scaling to 1 vCPU, or run on a time-limited evaluation window. This is typically delivered as a
: Optimized for stability and reliability, containing only bug fixes and vulnerability patches without new major features. 4. Recent Architectural Shifts Starting with versions like
virt-install --name FortiGate_VM \ --memory 2048 --vcpus 2 \ --import --disk fortios.qcow2 \ --disk fgt-logs.qcow2,size=30 \ --network bridge=virbr0,model=virtio \ --noautoconsole Use code with caution. Copied to clipboard 🌐 Step 4: Initial CLI Configuration
: Add a second virtual disk (e.g., 30 GB+) for logs and data. ⌨️ Step 3: Deployment Commands (KVM/QEMU) Use virt-install to build the VM around the existing image:
When you download FortiOS in this format, you receive a pre-configured virtual disk file containing the FortiOS operating system. It features:
