​​Introduction to FGT_VM64_KVM-v6-build1343-FORTINET.out.kvm.zip​​

This KVM-compatible FortiGate Virtual Machine package (v6.4.14 build1343) provides enterprise-grade network security for virtualized environments, addressing critical vulnerabilities disclosed in Fortinet’s Q1 2025 security advisories. Designed for cloud service providers and DevOps teams, the solution delivers 10Gbps threat inspection throughput while maintaining compatibility with OpenStack and VMware virtualization platforms.

The software supports nested virtualization configurations on Intel VT-x/AMD-V enabled hosts, making it ideal for testing multi-tenant security policies in lab environments. System administrators can deploy it on KVM hypervisors running Linux kernel 5.4+ without requiring hardware security modules.
