Bug description:
  While trying to add multiple disks to ubuntu guest on an ubuntu KVM, the following error is reported.
  Error: internal error: process exited while connecting to monitor: qemu-system-ppc64: -drive file=/dev/sdd,format=raw,if=none,id=drive-scsi0-0-0-0,cache=none,aio=native: Duplicate ID 'drive-scsi0-0-0-0' for drive

  It seems libvirt is using the same id for more than one disk. My
  impression is that something is wrong with the libvirt being used in
  Ubuntu 16.04.x.

  The target device parsing logic which generates the device alias has
  gone wrong as the XML used has the target dev names given in unusual
  format as vd2, vd3 where usual nomenclature is to have
  /^[fhv]d[a-z]+[0-9]*$/.

  The following regex should be followed while assigning the disk name: (regex) /^[fhv]d[a-z]+[0-9]*$/
  However, note that any trailing string of digits is simply ignored by libvirt.

  A patch has been sent upstream.

  The patch has been accepted upstream. commit 5729746.
