The value of machine_type getted from machines.cfg is incorrect on arm, it should be cut before used.

The disk device qemu command line has two configurations:
   1). blockdev config, eg:
       -blockdev node-name=file_image1,driver=file,filename=/var/**.qcow2
       -blockdev node-name=drive_image1,driver=qcow2,file=file_image1

   2). disk drive config, eg:
       -drive id=drive_image1,if=none,format=qcow2,file=/var/***.qcow2

If disk drive config, the expect value should be:
 {'device': 'drive_image1', 'qdev': 'image1', 'format': 'qcow2'}

If blockdev config, the expect value should be:
 {'node-name': 'drive_image1', 'qdev': 'image1', 'format': 'qcow2'}
