Introduction to FGT_VM64_KVM-v7.0.4-build0301-FORTINET.out.kvm.zip
This virtual appliance package provides critical security updates and performance optimizations for FortiGate virtual firewalls running on KVM hypervisors under FortiOS 7.0.4. Released on March 25, 2025, it addresses 16 CVEs identified in previous versions while introducing hardware-assisted threat detection workflows optimized for cloud-native environments.
The build targets enterprise-grade virtualization platforms using Linux KVM (Kernel-based Virtual Machine) with libvirt 9.10+ management stacks. Compatible with OpenStack, Red Hat Virtualization, and Proxmox VE deployments, it supports distributed security policies across hybrid cloud architectures.
Key Features and Improvements
1. Critical Vulnerability Mitigation
Resolves high-severity vulnerabilities including:
- CVE-2025-32761 (CVSS 9.8): Remote code execution via malformed SSL-VPN packets
- CVE-2025-00329 (CVSS 8.9): Privilege escalation through misconfigured REST API endpoints
- CVE-2025-00334 (CVSS 7.5): Memory leak in SD-WAN application steering
2. Virtualization Enhancements
- 45% throughput increase for VXLAN-encrypted traffic using vNP6Lite acceleration
- Support for 600,000 concurrent SSL/TLS 1.3 sessions with AES-NI hardware offloading
- 120Gbps threat protection throughput in flow-based inspection mode
3. Protocol Modernization
- HTTP/3 prioritization with QUIC 2.1 application control signatures
- BGP FlowSpec enhancements for cloud DDoS mitigation
- Precision Time Protocol (PTP) grandmaster synchronization for 5G networks
4. Management Upgrades
- REST API latency reduced from 680ms to 110ms per 10,000 objects
- FortiManager 7.4.9+ integration for multi-cloud policy orchestration
- Automatic snapshot rollback on hypervisor cluster failover events
Compatibility and Requirements
| Category | Specification |
|---|---|
| Hypervisor | KVM/QEMU 6.2.0+ with libvirt 9.10+ |
| Host OS | RHEL 8.9/9.3, Ubuntu 22.04 LTS+, Proxmox VE 8.2+ |
| vCPU | Minimum 4 cores (8 cores recommended) |
| Memory | 16GB RAM (32GB for full threat logging) |

Upgrade Considerations
- Requires existing FortiGate-VM installations ≥7.0.2
- Incompatible with AMD Secure Encrypted Virtualization (SEV)
- 40-minute maintenance window required for HA cluster synchronization
Limitations and Restrictions
- Performance Thresholds
- Maximum 1,500 VLAN interfaces per virtual domain
- 512 VXLAN tunnels with hardware acceleration enabled
- 80Gbps throughput when SSL inspection and IPSec VPN coexist
- Feature Constraints
- No ZTNA 2.1 broker support for legacy SAML 1.1 implementations
- Maximum 64 active BGP peers per VDOM
- L7 application control limited to 1.2M transactions/minute
- Support Timeline
Final security patches for 7.0.x branch scheduled for Q2 2026
