What matters is what the domU USES the block device as. If you use
some kind of installer to setup domU, then it will CREATE partitions
(and optionally LVM) on top of the block device.
If you create the domU manually (e.g. from template) then it's your
choice whether or not to create a partition on it.

Here's something that would help you understand better. In domU, do a
"cat /proc/partitions" and "fdisk -lu".
You should see that domU sees the "disk" HAS changed, but the
partition ON that disk remains the same.
