Live migration streams

File stream

You can use the file stream to import from a locally accessible POSIX file source.

{
    <format unique parameters>
    "stream": {
        "type": "file",
        "file_path": "FILE_PATH"
    }
}

{
    "type": "raw",
    "stream": {
        "type": "file",
        "file_path": "/mnt/image.raw"
    }
}

HTTP stream

You can use the HTTP stream to import from a remote HTTP or HTTPS web server.

{
    <format unique parameters>
    "stream": {
        "type": "http",
        "url": "URL_PATH"
    }
}

{
    "type": "raw",
    "stream": {
        "type": "http",
        "url": "http://download.ceph.com/image.raw"
    }
}

S3 stream

You can use the s3 stream to import from a remote S3 bucket.

{
    <format unique parameters>
    "stream": {
        "type": "s3",
        "url": "URL_PATH",
        "access_key": "ACCESS_KEY",
        "secret_key": "SECRET_KEY"
    }
}

{
    "type": "raw",
    "stream": {
        "type": "s3",
        "url": "http://s3.ceph.com/bucket/image.raw",
        "access_key": "NX5QOQKC6BH2IDN8HC7A",
        "secret_key": "LnEsqNNqZIpkzauboDcLXLcYaWwLQ3Kop0zAnKIn"
    }
}

NBD stream

You can use the NBD stream to import from a remote NBD export.

nbd-uri parameter must follow the NBD URI format. The default NBD port is 10809.

For more information, see The NBD Uniform Resource Indicator (URI) format.

{
            <format unique parameters>
            "stream": {
                "type": "nbd",
                "uri": "<nbd-uri>",
            }
        }

The following is a source-spec JSON file that imports a raw-format image from an NBD export located at nbd://nbd.ceph.com/image.raw.

{
            "type": "raw",
            "stream": {
                "type": "nbd",
                "uri": "nbd://nbd.ceph.com/image.raw",
            }
        }
