I believe you are stuck with the extra level of indirection -- that is
that partitions in your host (dom0) appear
as disks in your domU -- with both tools. I don't think you can feed a
partition up without a corresponding virtual disk :)
(Note that you don't have to use LVM for this -- regular partitions work
