Build 1262 sits in a for virtualization: it is mature enough to have resolved early 7.2.x virtio-driver crashes, but predates 7.2.4’s VPN negotiation issues reported on certain KVM hosts. Several community forums (r/fortinet, Reddit, Fortinet Developer Network) indicate that 7.2.3.f build1262 has stable packet forwarding performance under moderate load (1–5 Gbps with IPS enabled).

Basic configuration using the CLI console:
execute license upload tftp <license.lic> <tftp-server-ip> Without a valid license, the VM will revert to a read-only evaluation mode after 15 days. Build 1262 has known parameters that improve KVM throughput. Add these to the VM’s XML (using virsh edit fortigate-723f ): 1. Multi-Queue virtio-net <interface type='bridge'> <model type='virtio'/> <driver name='vhost' queues='2'/> <virtualport type='openvswitch'/> </interface> This allows vCPU affinity to transmit/receive queues, reducing packet loss under DPI. 2.
