For system administrators deploying FortiGate on Linux-based hypervisors, the .qcow2 image is the gold standard. Unlike raw disk images, QCOW2 files are highly flexible. They only consume storage space as the data grows (sparse allocation), which prevents massive disk waste during initial provisioning. Furthermore, QCOW2 supports native copy-on-write snapshots, allowing administrators to safely take a snapshot of their FortiGate instance before pushing major firewall policy changes or performing an OS upgrade. Core Features of FortiOS 7.2.3
To run this specific image natively within a Linux host environment (such as Ubuntu, RHEL, or Proxmox), the qcow2 image must be imported using standard virtualization management utilities. 1. Preparing the Environment

What are you planning to use (e.g., Proxmox, QEMU/KVM, OpenStack)?
Enable this to offload packet processing to user space, which can triple throughput for UDP firewall rules. forward traffic logging will fail.
This guide provides a general overview. Specific steps, especially for configuring the FortiGate services and network settings, should be referenced from Fortinet's official documentation due to the proprietary nature of these configurations.
FortiGate architectures demand a secondary virtual drive dedicated strictly to system logging and WAN optimization caches. Without a secondary drive attached, forward traffic logging will fail.
