Failed to create vm with --image and --block

when using --image and --block-device to create vm,
it failed with the follow logs:

DEBUG (shell:803) Block Device Mapping is Invalid: Mapping image to local is not supported. (HTTP 400) (Request-ID: req-951fbde1-f934-40c7-bbb7-a3b298f4f11f)

The follows are my commands:
nova boot cirros --flavor m1.tiny \
 --image fc2c4d25-8a71-4229-b9d9-82f79cac3500 \
 --nic net-id=3c02041b-9fa3-4f65-82c2-39e211bfe27f \
 --block-device id=fc2c4d25-8a71-4229-b9d9-82f79cac3500,source=image,dest=volume,bus=virtio,type=disk,size=1,device=vda

And my openstack version is master

In the method named from_api in nova/block_device.py,

            if source_type == 'image' and destination_type == 'local':
                raise exception.InvalidBDMFormat(
                    details=_("Mapping image to local is not supported."))

In the method named _boot in novaclient/v2/servers.py

            if image:
                bdm_dict = {'uuid': image.id, 'source_type': 'image',
                            'destination_type': 'local', 'boot_index': 0,
                            'delete_on_termination': True}
                block_device_mapping_v2.insert(0, bdm_dict)

Novaclient request nova service with error params, then the error occured

    Remove image to local block device mapping

    In the method named from_api in nova/block_device.py,

        if source_type == 'image' and destination_type == 'local':
            raise exception.InvalidBDMFormat(
                details=_("Mapping image to local is not supported."))

    While, in the method named _boot in novaclient/v2/servers.py

        if image:
            bdm_dict = {'uuid': image.id, 'source_type': 'image',
                        'destination_type': 'local', 'boot_index': 0,
                        'delete_on_termination': True}
            block_device_mapping_v2.insert(0, bdm_dict)

    Because of the above, if using --image and --block-device
    params at the same time to create vm, nova would
    raise InvalidBDMFormat exception

    To resolve this problem, remove the codes in novaclient which
    conflict with nova
