From: Paolo Bonzini Date: Mon, 24 May 2021 06:57:52 -0400 Subject: vl: plug -object back into -readconfig Git-commit: 49e987695a1873a769a823604f9065aa88e00c55 Commit bc2f4fcb1d ("qom: move user_creatable_add_opts logic to vl.c and QAPIfy it", 2021-03-19) switched the creation of objects from qemu_opts_foreach to a bespoke QTAILQ in preparation for supporting JSON syntax in -object. Unfortunately in doing so it lost support for [object] stanzas in configuration files and also for "-set object.ID.KEY=VAL". The latter is hard to re-establish and probably best solved by deprecating -set. This patch uses the infrastructure introduced by the previous two patches in order to parse QOM objects correctly from configuration files.
