For a couple of releases we have been warning Encrypted images are deprecated Support for them will be removed in a future release. You can use 'qemu-img convert' to convert your image to an unencrypted one. This warning was issued by system emulators, qemu-img, qemu-nbd and qemu-io. Such a broad warning was issued because the original intention was to rip out all the code for dealing with encryption inside the QEMU block layer APIs. The new block encryption framework used for the LUKS driver does not rely on the unloved block layer API for encryption keys, instead using the QOM 'secret' object type. It is thus no longer appropriate to warn about encryption unconditionally. When the qcow/qcow2 drivers are converted to use the new encryption framework too, it will be practical to keep AES-CBC support present for use in qemu-img, qemu-io & qemu-nbd to allow for interoperability with older QEMU versions and liberation of data from existing encrypted qcow2 files. This change moves the warning out of the generic block code and into the qcow/qcow2 drivers. Further, the warning is set to only appear when running the system emulators, since qemu-img, qemu-io, qemu-nbd are expected to support qcow2 encryption long term now that the maint burden has been eliminated.
