The get_guest_config() function returns an instance of the nova.virt.libvirt.config.LibvirtConfigGuest object. That class has defined attributes for setting various parts of the XML config. You can't simply set arbitrary attributes and expect it to work - you'll need to define how it is exposed in the LibvirtConfigGuest object (or one of the related classes that it uses) and then impl the code to generate the XML dom from that attribute.
