Introduction to FGT_VM64_KVM-v7.4.1.F-build2463-FORTINET.out.kvm.zip

This KVM-optimized virtual machine package delivers FortiOS 7.4.1 for FortiGate-VM64 deployments, released on March 15, 2025 under Fortinet’s Virtual Security Compute Program. Designed for hybrid cloud environments, it provides enterprise-grade firewall and SD-WAN capabilities with hardware-assisted acceleration through KVM’s virtio drivers.

The build 2463 iteration specifically addresses 9 critical CVEs in previous 7.4.x versions while introducing native support for Red Hat Virtualization 4.3+ and Ubuntu Cloud 22.04 LTS hosts. Compatible with all x86_64 KVM hypervisors, this release enables automated provisioning through OpenStack Metadata Service (cloud-init).
