From 62a01a27f7f67853553679201e8617ccd28e965b Mon Sep 17 00:00:00 2001 From: Max Reitz Date: Fri, 1 Feb 2019 20:29:34 +0100 Subject: block: BDS options may lack the "driver" option When BDSs are created by qemu itself (e.g. as filters in block jobs), they may not have a "driver" option in their options QDict. When generating a json:{} filename, however, it must always be present.
