If you have encountered this term while searching for virtual firewall images, you are likely dealing with a build intended for KVM (Kernel-based Virtual Machine) environments. This article will dissect each segment, explain the underlying technologies, and provide actionable guidance on deploying this artifact.
The search term refers directly to a specific deployment image file used in enterprise network security architecture. Broken down, this string represents the FortiGate Virtual Machine (64-bit) tailored for the Kernel-based Virtual Machine (KVM) hypervisor, running FortiOS version 7.2.3 (Build 1262) , exported as a fresh QCOW2 virtual disk file.
Let’s split it into logical parts:
