If so, then I guess we might actually need some kind of granularity here. eg if the user has a 1200 MB guest, and they want to use 1 GB huge pages, then there's a choice between 2 * 1GB huge pages, or 1 x 1GB and n * 4M huge pages, or an error requiring that their guest RAM is a multiple of requested huge page size. So perhaps we do need some "policy" attribute on the <hugepages/> element to indicate desired behaviour here.
