Introduction to FGT_VM64_KVM-v6-build0528-FORTINET.out Software
This virtual appliance package delivers FortiOS 6.4.15 optimized for KVM hypervisors, enabling enterprise-grade network security in cloud and hybrid environments. Designed as a maintenance release, it addresses critical vulnerabilities while enhancing interoperability with modern virtualization stacks like OpenStack and Kubernetes.
The build specifically targets FortiGate-VM64 instances running on KVM hosts with hardware-assisted virtualization (Intel VT-x/AMD-V). Compatibility extends to x86_64 servers using QEMU 6.2+ and libvirt 8.0+ management tools. Officially released on May 28, 2025, this version includes optimizations for high-density virtual security deployments.
