[Qemu-devel] [PATCH v3 15/26] qemu-img/qemu-io: don't prompt for passwords if not required |
Date: |
Mon, 15 Feb 2016 16:10:48 +0000 |
The qemu-img/qemu-io tools prompt for disk encryption passwords
regardless of whether any are actually required. Adding a check
on bdrv_key_required() avoids this prompt for disk formats which
have been converted to the QCryptoSecret APIs.
This is just a temporary hack to ensure the block I/O tests
continue to work after each patch, since the last patch will
completely delete all the password prompting code.
