This is preferrable to -nographic which (in addition to disabling graphics output) redirects the serial port to stdio and on OpenBIOS enables the firmware's serial console.

Am I right in thinking that -display none vs -nographic has *no* effect on guest machine ABI ? I think we're safe based on my reading of it, particularly since we use -nodefaults and -nodefconfig, but want to confirm there's no edge case i'm not aware of.
