If XML disappears after saving it, this usually indicates that either you made a mistake and used the wrong XML element or in the wrong place, or that your libvirt version is too old to support it. You can use the virt-xml-validate too to verify your XML file against the schema for your installed version of libvirt, which will report any errrors.
