Subject: [PATCH] qemu: block: Don't skip creation of 'luks' formatted images
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
libvirt treats 'luks' images as raw+encryption. The logic in
qemuBlockStorageSourceCreateFormat skipped the creation if the requested
image was raw but didn't take into account the encryption.
This manifested itself e.g. when attempting to do a virsh blockcopy with
the following XML:
<disk type='file' device='disk'>
<driver name='qemu' type='raw'/>
<source file='/tmp/enccpy'>
<encryption format='luks'>
<secret type='passphrase' uuid='0a81f5b2-8403-7b23-c8d6-21ccc2f80d6f'/>
</encryption>
</source>
</disk>
Where qemu would report the following error:
unable to execute QEMU command 'blockdev-add': Volume is not in LUKS format
rather than actually formatting the image first.
