Yes. For this purpose, you create one LV on dom0, map it to domU as
xvda, and install domU like what you'd do with file-based disk image.

I'm not quite sure what you mean, but you can do this :
- create two LVs on dom0, map it to domU as xvda1 (for / ) and xvda2
(for swap). You don't need a separate /boot.
- do mkfs.ext3 and mkswap on dom0 directly on that LV (not creating
partition on top of it)
- populate domU's filesystem (for example, by extracting "templates"
like the one from jailtime.org, or by copying from a working domU.)
- create a suitable initrd
