[Michal Privoznik <mprivozn@xxxxxxxxxx>]

Compare:

  # virsh domblkstat freebsd hdd
  error: Failed to get block stats freebsd hdd
  error: invalid argument: invalid path: hdd

with:

  # virsh domblkstat freebsd hdd
  error: Failed to get block stats for domain 'freebsd' device 'hdd'
  error: invalid argument: invalid path: hdd
