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
