Bo Tu Oct. 30, 2015, 7:13 a.m. UTC 
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.
Warning message expected for s390x when drive without device.
