I'll try again.

nographic does not make sense here, genericarm64 supports graphics as
far as I know. The limitations of the test environment should not be
hardcoded into the machine definition.

There are patches which I sent recently against master which fix that
issue in a better way and will mean this is not needed. I am therefore
not going to take that as it is confusing, incorrect and not actually
needed.

Cheers,
