It slows down disk accesses by quite a bit, as the dom0 has to go through a
whole extra layer (the dom0 VFS layer) to get to your data.  *Definitely*
not a good thing for production.

Didn't someone post some LVM vs disk image performance stats to either here
or xen-devel@ a while ago, or am I hallucinating?  (I'm on the train, so no
google to confirm my suspicions).
