The XML allows <encryption format='unencrypted'/>, this implementation canonicalizes the internal representation so that "vol->encryption" is non-NULL iff the volume is encrypted. Note that partial encryption information (e.g. specifying an encryption format, but not the key/passphrase) is valid, libvirt will automatically choose value for the missing information during volume creation. The user can read the volume XML, and use the unmodified <encryption> tag in future operations (without having to be able to understand) its contents. * docs/formatstorage.html, docs/formatstorage.html.in: Document storage volume encryption options * src/storage_conf.c, src/storage_conf.h: Hook up storage encryption XML handling * tests/storagevolschemadata/vol-qcow2.xml: Test case for encryption schema changes
