If you use the LV as a whole Xen file system, you have to go through 
some extra steps using "kpartx" to access its internal partitions. Tools 
tools like fdisk or parted used inside the Xen system whinge less, and 
you can use partition resizing tools inside of the guest domain. And I 
don't think that RedHat's anaconda installer is happy *at all* about 
dealing with partitions like xvda1 without an xvda device behind them, 
but my memory of that is from a while ago. You could try it.
