From: David Hildenbrand <david@redhat.com>
Let's register a RAM block notifier and react on remap notifications.
Simply re-apply the settings. Exit if something goes wrong.
Note: qemu_ram_remap() will not remap when RAM_PREALLOC is set. Could be
that hostmem is still missing to update that flag ...
