[Qemu-devel] [PATCH RFC v9 6/7] qemu-iotests: s390x: fix test 051

[Bo Tu]

The tests for device type "ide_cd" should only be tested for the pc
platform.
The default device id of hard disk on the s390 platform differs to that
of the x86 platform. A new variable device_id is defined and "virtio0"
set for the s390 platform. A x86 platform specific output file is also
needed.
A new filter was added to filter orphan warnings.
