ugh, and double ugh. this violates the KISS 'keep it super simple'
principle, and I can only see the extra layers of complexity leading to
more frustration.
I would instead run LVM only on dom0, and have your domU's creating file
systems directly on the virtual devices mapped to said LVs. if you
need to grow a file system, you resize the LV from dom0, and then growfs
in the domU
