From: Amos Kong <akong@xxxxxxxxxx>
This test adds a usb storage for the guest, and do some check from monitor and
inside the guest.
Changes from v1:
- use old options to add a usb disk to guest
'-usbdevice disk:format=qcow2:/tmp/usbdevice.qcow2'
- identify device name of new disk by '/dev/disk/by-path/'
- match device with the detail output of 'lsusb -v'
- create disk image by pre_cmd
Changes from v2:
- reuse the new interface to add a usb disk to guest
- report a rh-bug 727725
Changes from v3:
- Use a better string matching pattern for fdisk output
- Mount USB device, copy file to it, unmount, mount
again and then compare the md5sum of both files
