Procedure:

** Configure DRAC

** Set BIOS boot sequence - HDD, CDROM

** ks.cfg packages to be removed from Core/Base
install 
cdrom
reboot
%include /rpms.to.remove.from.Core.Base

    grep = rpms.295.names|grep -v ?|sed -e 's/^= //'>rpms.REMOVE.from.Core.Base

** ks.cfg (partitioning part)
part /boot --fstype=ext3 --size=100 --asprimary --ondisk=sda
part swap --size=256 --grow --maxsize=6000 --asprimary --ondisk=sda 
part / --fstype=ext3 --size=1 --grow --maxsize=16000 --asprimary --ondisk=sda 
# physical volumes for holding logical volumes with Xen DomUs.
part pv.01 --size=1 --grow --asprimary --ondisk=sda
part pv.02 --size=1 --grow --ondisk=sdb
