Yes, RH's Xen installs LVM on domU by default when using virt-manager. 
The problem with this approach is when domU's storage is also located on 
dom0's LV. This makes it very difficult (if not impossible) to mount 
domU's storage on dom0 (for example, when troubleshooting is needed).
In my setup I ended up creating domUs manually (using a template 
.tar.gz), mapping an LV on dom0 to (h/s/xv)da1 for root and (h/s/xv)da2 
for swap on domU. It's easier to manage this way.
