Introduction to FGT_VM64_KVM-v7.2.2.F-build1255-FORTINET.out.kvm.zip

This KVM-optimized virtual machine package provides enterprise-grade network security for cloud and hybrid environments, delivering FortiOS 7.2.2 Feature Release (build 1255) on Linux KVM hypervisors. Designed as a software-defined extension of FortiGate next-generation firewalls, it enables consistent security policy enforcement across physical and virtual infrastructure.

The package specifically supports Ubuntu 20.04 LTS/CentOS 7+ KVM hosts and integrates with major cloud platforms like Tianyi Cloud through customized qcow2 disk formats. While official release notes remain restricted to licensed partners, build metadata suggests Q1 2025 deployment aligned with Fortinet’s quarterly security update cycle.
