Introduction to FGT_VM64_HV-v6-build1112-FORTINET.out.hyperv.zip

This software package provides FortiOS 6.4.15 for FortiGate Virtual Machine (VM) deployments on Microsoft Hyper-V hypervisors, optimized for enterprises requiring flexible network security in virtualized environments. Designed as a native VHDX image, it delivers full next-generation firewall capabilities with 40 Gbps threat protection throughput, supporting modern data center architectures and hybrid cloud deployments.

The build specifically targets HV virtual machines (model VM64-HV) with enhanced SR-IOV support for low-latency network processing. It maintains backward compatibility with Hyper-V 2019/2022 clusters while introducing native IPv6 dual-stack operations – a critical upgrade for organizations transitioning to modern network protocols.
