When support for networks that used an existing bridge was added, we had to maintain backward compatibility, so we decided that the new type of network would be identified by setting <forward mode='bridge'/> on a network that has a bridge name defined.) No, that wouldn't have worked in any older release of libvirt. Perhaps you've forgotten that you previously had <forward mode='bridge'/> in your definition?
