LXD developers have reported that [object] stanzas have stopped working in configuration files.
The problem is that QEMU 6.0 switched the creation of objects from qemu_opts_foreach to a bespoke QTAILQ, in preparation for supporting JSON syntax in -object. Entries from the configuration file however do not go through object_option_parse, and are thus lost. Of the many fixes that are possible, I chose one that is slightly more invasive but more consistent with the plans for keyval-ification of options such as -M and -accel. -set was also broken by the same change, but for simplicity I chose not to add it back yet. However, this series will report the breakage instead of failing silently. The first two patches of this series are thus a reduced version of https://patchew.org/QEMU/20210513162901.1310239-1-pbonz...@redhat.com/ ([PATCH 00/14] vl: compound properties for machines and accelerators), with the -set infrastructure removed. The third is very simple and uses the newly-provided hooks to parse objects from configuration files.
