+ Storage volumes may be encrypted, the XML snippet described below is used
+ to represent the details of the encryption. It can be used as a part
+ of a domain or storage configuration.
+ </p>
+ <p>
+ The top-level tag of volume encryption specification
+ is <code>encryption</code>, with a mandatory
+ attribute <code>format</code>. Currently defined values
+ of <code>format</code> are <code>default</code> and <code>qcow</code>.
+ Each value of <code>format</code> implies some expectations about the
+ content of the <code>encryption</code> tag. Other format values may be
+ defined in the future.
+ </p>
+ <p>
+ The <code>encryption</code> tag can currently contain a sequence of
+ <code>secret</code> tags, each with mandatory attributes <code>type</code>
+ and <code>uuid</code>. The only currently defined value of
+ <code>type</code> is <code>passphrase</code>. <code>uuid</code>
+ refers to a secret known to libvirt. libvirt can use a secret value
+ previously set using <code>virSecretSetValue()</code>, or, if supported
+ by the particular volume format and driver, automatically generate a
+ secret value at the time of volume creation, and store it using the
+ specified <code>uuid</code>.
+ </p>
+ <p>
+ </p>
+ <h3>
+ <a name="StorageEncryptionDefault" id="StorageEncryptionDefault">"default" format</a>
+ </h3>
+ <p>
+ <code><encryption type="default"/></code> can be specified only
+ when creating a volume. If the volume is successfully created, the
+ encryption formats, parameters and secrets will be auto-generated by
+ libvirt and the attached <code>encryption</code> tag will be updated.
+ The unmodified contents of the <code>encryption</code> tag can be used
+ in later operations with the volume, or when setting up a domain that
+ uses the volume.
+ </p>
+ <h3>
+ <a name="StorageEncryptionQcow" id="StorageEncryptionQcow">"qcow" format</a>
+ </h3>
+ <p>
+ The <code>qcow</code> format specifies that the built-in encryption
+ support in <code>qcow</code>- or <code>qcow2</code>-formatted volume
+ images should be used. A single
+ <code><secret type='passphrase'></code> element is expected. If
+ the <code>secret</code> element is not present during volume creation,
+ a secret is automatically generated and attached to the volume.
+ </p>
+ <h2>
+ <a name="example" id="example">Example</a>

+ Here is a simple example, specifying use of the <code>qcow</code> format:
