From ed61e0b368859b25beb5259f84edd4910cd5218f Mon Sep 17 00:00:00 2001 From: Peter Krempa Date: Wed, 17 May 2017 17:16:15 +0200 Subject: [PATCH] qemu: driver: Allow passing disk target as top image with block commit Since we allow active layer block commit the users are allowed to commit the top of the chain (e.g. vda) into the backing image. The API would not accept that parameter, as it tried to look up the image in the backing chain. Add the ability to use the top level image target name explicitly as the top image of the block commit operation.
