Or you could just take the view this is a pre-migration capability check,
and that admin (or mgmt app) must ensure sufficient free hugepages on the destination before attempting migration. If this isn't satisfied then 
XenD can just fail / abort the migration op and leave it running on original
host.
And do something to prevent new hugepages from being allocated during the dirty logging phase?
