[Qemu-block] [PULL 20/32] block/qdev: Allow configuring rerror/werror with qdev properties |
Date: |
Fri, 8 Jul 2016 19:21:32 +0200 |
The rerror/werror policies are implemented in the devices, so that's
where they should be configured. In comparison to the old options in
-drive, the qdev properties are only added to those devices that
actually support them.
If the option isn't given (or "auto" is specified), the setting of the
BlockBackend is used for compatibility with the old options. For block
jobs, "auto" is the same as "enospc".
