Because you can resize such partitions more dynamically, and because 
RedHat's default instlallers readlly try to insist on doing this, and 
because by distributiong the LVM across multiple partitions you can 
noticeably improve performance.
Doing it inside the Xen instance is not as useful, though. Let Dom0 do 
the LVM!
