[Bug 1884507] Re: 'none' machine should use 'none' display option

[Thomas Huth]

Actually, thinking about this twice, I think you made a wrong assumption
here. "-display" is about the  GUI backend that should be used. "-M" is
about the emulated hardware. The emulated hardware options should never
influence the host backend options. And it is e.g. perfectly valid to
use the "none" machine as CPU instruction simulator in a GTK window, so
it does not make sense to force the disablement the GUI in that case.

Title:
  'none' machine should use 'none' display option

Status in QEMU:
  Invalid

Bug description:
  As the 'none' machine doesn't have any peripheral (except CPU cores)
  it is pointless to start a display. 

  '-M none' should imply '-display none'.
