Now that qcow & qcow2 are wired up to get encryption keys
via the QCryptoSecret object, all traces of code which
had to deal with prompting for passwords can be ripped
out.
When the image is initially opened, the encryption key
must be available immediately, or an error will be
reported.
$ qemu-system-x86_64 -drive file=secret.qcow2
qemu-system-x86_64: -drive file=secret.qcow2: Image is encrypted but no secret
is provided
Users must provide the secret with -object
$ echo 123456 > mypasswd.txt
qemu-system-x86_64 -drive file=secret.qcow2,keysecret=sec0 -object
secret,file=mypasswd.txt,id=sec0
The BDRV_O_NO_IO flag allows this error to be skipped,
for use when 'qemu-img info' wants to open the file
to query the headers, but not perform any actual I/O
operations.
