Sorry, maybe I haven''t made it clear on my last posting.  On this Xen
box I have NO partition using the entire HD.  Is it possible
repartition the HD without wiping out the whole system?


I haven''t run LV sometimes.  Most the time I partition HD before
installing the OS, such as /boot, /root, /home, /swap, /var, etc. 
However on Xen box (Virtual Machine) I use the entire HD.  Because it
would be difficult for me to forecast the number of guests to be
created in advance.

Whether you meant on both /etc/xen/*.cfg and
/etc/udev/rules.d/z25_persistent-net.rules files ?
