One thing was overlooked since the start, that anonymous creations of qdev (then realize() the device) requires the machine object's presence, as all these devices need to be attached to QOM tree, by default to path "/machine/unattached". The test didn't crash simply because container_get() has an implicit semantic to silently create any missing container, hence what happened here is container_get() (when running these tests) will try to create containers at QOM path "/machine" on the fly. That's probably unexpected by the test, but worked like charm before. We're going to fix device_set_realized() soon, but before that make the test case prepared, by creating the machine object on its own. Reviewed-by: Philippe Mathieu-Daudé Reviewed-by: Daniel P.

It is still a "container" but not strictly. Note that it _may_ get a container (at "/machine") in our current unit test of test-qdev-global-props.c before all these changes, but it's probably unexpected and worked by accident. Switch to an explicit object_resolve_path_component(), with a side benefit that qdev_get_machine() can happen a lot, and we don't need to split the string ("/machine") every time. This also paves way for making the helper container_get() never try to return a non-container at all.
