# SeaBIOS 1.11.0 added support for VGA emulation over a serial port. If
# this is configured in SeaBIOS, then -nographic causes some extra junk to
# end up on the serial console, which interferes with our tests. This
# workaround unfortunately causes qemu to issue a warning 'externally
# provided fw_cfg item names should be prefixed with "opt/"', but there
# doesn't seem to be a better option.
