I'm not entirely sure what that would do ? Is that for when people want
to have a specific size of hugepages ? 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.
