How do you add a new attribute to the device tree and, when a supplied device tree lacking said attribute, distinguish between a device tree from an old version of qemu (i.e. use the old default) and a partial device tree from the VM manager (i.e. use the new default) ? > NB the device tree contains no host configuration information. So, it wouldn't e.g. include the path to the image file for a block device? That would always be specified on the command line?
