[Qemu-devel] [PULL v2 13/16] iotests: Add -display none to the qemu options

[Max Reitz <mreitz@redhat.com>]

Without this argument, qemu will print an angry message about not being
able to connect to a display server if $DISPLAY is not set.  For me,
that breaks iotests.supported_formats() because it thus only sees
["Could", "not", "connect"] as the supported formats.
