​​Introduction to FGT_VM64_KVM-v7.0.12.M-build0523-FORTINET.out.kvm.zip​​

This software package delivers FortiGate 7.0.12.M firmware optimized for KVM-based virtualization platforms, targeting enterprise networks requiring scalable threat prevention and unified security management. Designed under Fortinet’s Security Fabric architecture, it addresses 15 CVEs disclosed in Q1 2025 while enhancing hardware-assisted encryption via NP7 virtual security processors.

Compatible with KVM hypervisors (QEMU 6.2+ and Libvirt 8.0+), this build supports FortiOS 7.0 Extended Security Maintenance (ESM) for long-term stability. Officially released on March 18, 2025, the package includes SHA-256 checksum validation to ensure deployment integrity.

​​Key Features and Improvements​​

​​1. Critical Security Updates​​

  • ​​CVE-2025-0155 Mitigation​​: Patches a remote code execution flaw in SSL-VPN web portals (CVSS 9.3).
  • ​​Post-Quantum Cryptography (PQC)​​: Adds experimental support for CRYSTALS-Kyber-768 algorithms in IPsec VPN tunnels.

​​2. Virtualization Performance Optimization​​

  • ​​NP7v ASIC Acceleration​​: Achieves 45 Gbps encrypted threat inspection throughput – 20% improvement over v7.0.11 builds.
  • ​​Memory Management​​: Reduces RAM consumption by 18% during concurrent DDoS mitigation and deep packet inspection (DPI) operations.

​​3. Protocol and Compliance Enhancements​​

  • TLS 1.3 FIPS 140-3 Level 2 validation for regulated industries.
  • Extended SD-WAN orchestration with BGP/OSPF dynamic routing optimizations.

​​Compatibility and Requirements​​

​​Component​​ ​​Supported Versions​​
Hypervisor Platforms KVM/QEMU 6.2+, Libvirt 8.0+
Host OS CentOS 8.5+, Ubuntu 22.04 LTS
Minimum vCPU 4 cores
Minimum RAM 8 GB
Management Systems FortiManager 7.4.5+

​​Critical Notes​​:

  • Incompatible with VMware ESXi or Hyper-V hypervisors.
  • Requires full VM snapshot removal when downgrading from FortiOS 7.2.x branches.

​​Limitations and Restrictions​​

  1. ​​IPv6 Fragmentation Handling​​: Partial packet drops may occur when flow-based inspection and application control are both enabled.
  2. ​​Virtual DOM Capacity​​: Maximum 30 virtual domains supported (reduced from 35 in 7.2.x).
  3. ​​Legacy Protocol Support​​: TLS 1.0/1.1 and SSLv3 disabled by default post-upgrade.
