Supports only virStorageVolCreateXML, not virStorageVolCreateXMLFrom.
Curiously, qemu-img does not need the passphrase for anything to create
an encrypted volume. This implementation thus does not need to touch
any secrets to work with cooperating clients. More generic passphrase
handling is added in the next patch.
* src/storage_backend.c: Request encryption when creating qcow/qcow2
files
* src/storage_backend_disk.c, src/storage_backend_fs.c,
src/storage_backend_logical.c: Refuse to create volumes with
encryption params set.
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
