  Just define them appropriately in the configuration file for Xen.
 Something like this:

 disk    = [ 'phy:vg01/lv_guest1_root,sda1,w',
             'phy:vg01/lv_guest1_usr,sda2,w',
             'phy:vg01/lv_guest1_var,sda3,w',
            ... ]

  Then inside the /etc/fstab of the domU you'd have:

  /dev/sda1 /    ...
  /dev/sda2 /usr ...
  /dev/sda3 /var ...
