ovmf doesn't print a message when this happens, it just moves on to the next
boot option (probably the shell). You can forcibly get a message by running
fs0:\efi\boot\bootx64.efi from the shell.

On real hardware with production firmware, there is no shell so the boot
stops and you see the security violation message.
