Markus Armbruster 79b9d4bde7 accel: Unbreak accelerator fallback ... When the user specifies a list of accelerators, we pick the first one that initializes successfully. Recent commit 1a3ec8c156 broke that. Reproducer: $ qemu-system-x86_64 --machine accel=xen:tcg xencall: error: Could not obtain handle on privileged command interface: No such file or directory xen be core: xen be core: can't open xen interface can't open xen interface qemu-system-x86_64: failed to initialize Xen: Operation not permitted qemu-system-x86_64: /home/armbru/work/qemu/qom/object.c:436: object_set_accelerator_compat_props: Assertion `!object_compat_props[0]' failed. Root cause: we register accelerator compat properties even when the accelerator fails. The failed assertion is object_set_accelerator_compat_props() telling us off. Fix by calling it only for the accelerator that succeeded.
