DPDK+vNP offloading is supported on FortiGate instances with multiple vCPUs. Minimum RAM requirements differ from regular FortiGate-VM models, so consult the KVM Administration Guide for version‑specific guidelines.

Add multiple network interfaces (VirtIO is recommended for best performance). You will typically need one interface for management/WAN and others for LAN/DMZ.

: Always select virtio for disk buses and network interface models to achieve the lowest CPU overhead and highest throughput. fortios.qcow2

The VM reports “0 CPUs and 0 MB RAM” or “Invalid license”. DPDK+vNP offloading is supported on FortiGate instances with

Once logged in, navigate to . You will then select the product as FortiGate and the platform as KVM [15†L13-L14][8†L12-L15]. From there, you can download the latest firmware image for a "New deployment" of the VM [8†L14-L15].

Import the .qcow2 file as a QEMU appliance. GNS3 automatically configures the network interfaces to work with your topology. You will typically need one interface for management/WAN

“Why me?” she asked.

Unlike fixed-size formats (such as raw), QCOW2 files are typically dynamic, meaning they start small and grow only as data is written to them, optimizing storage utilization.

While specific steps vary by hypervisor, the general virtual hardware requirements for a stable environment include: Fortigate - Forti Stacks - Read the Docs
