So perhaps we do need some "policy" attribute on the <hugepages/> element to indicate desired behaviour here.
What about the following new element under <hugepages/> ?
enforce_hugepage_size=integer
Which feels a bit redundant (we're already under the <hugepages> element, after all). Maybe: <hugepages> <size strict='yes' unit='G'>1</size> </hugepages> where strict could be no if we are giving a hint but don't care if the hint cannot be honored (default yes if omitted), and where unit + value allows the user to input the size in a sensible unit (on output, we'd probably want to use unit='k' and spell out 1048576, for similarity with all our other memory interfaces that output in k for back-compat reasons). -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
