Always verify build checksums from Fortinet Support Portal.
: The downloaded qcow2 file is just the system disk. The FortiGate-VM also requires a separate, dedicated disk of at least 32GB for logging and reporting. You must manually create and attach this second disk to the VM before powering it on. You can do this with virt-manager or via the command line ( qemu-img to create the disk, then edit the VM's XML definition to attach it).
The file (properly identified as FGT_VM64_KVM-v7.2.3.F-build1262-FORTINET.out.kvm.qcow2 ) represents a specific, crucial version of the FortiGate Next-Generation Firewall virtual appliance, designed specifically for Linux KVM (Kernel-based Virtual Machine) environments. fgtvm64kvmv723fbuild1262fortinetoutkvmqcow2
