Part 2: System Requirements for VirtualBox

Before downloading, ensure your host machine can handle the load. Observed Anomalies:

| Component | Minimum Requirement | Recommended | | --- | --- | --- | | CPU | Intel Core i5 (VT-x/AMD-V) | Intel i7/i9 or AMD Ryzen 7 | | RAM | 4 GB (2 for host, 2 for VM) | 16 GB+ (give 4-8 GB to VM) | | Storage | 20 GB free | 50 GB SSD (for logs and updates) | | VirtualBox Version | 6.1 or newer | 7.0+ |

Note: FortiGate VM v7.4 and above require a minimum of 2 vCPUs and 4 GB RAM. Do not allocate only 1 CPU or the VM will kernel panic on boot.

Observed Anomalies:

• VirtIO drivers are not supported. Using Intel PRO/1000 results in 15% higher CPU utilization compared to bare metal/KVM.
• ASIC offload (NP6/CP8) is disabled. All inspection is done via host CPU (Software mode).
