to some VDO will not prevent it from being applied to any other VDO,
however any exception will result in applyToVDOs raising an exception.
If the 'readonly' keyword argument is False, the configuration will be
persisted after the method has been applied to all the VDOs (whether or
not it succeeded for any of them).
Arguments:

method(args, vdo)
