From d190698e6f806198da42c05c35b623760b6e1f00 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Tue, 10 Jun 2014 11:17:35 +0200 Subject: qom: allow creating an alias of a child<> property Child properties must be unique. Fix this problem by turning their aliases into links. The resolve function that forwards to the target property does not have any knowledge of the target property's type, so it works fine.
