I have a problem:

clearpart --all --drives=sda
part /boot --fstype ext3 --size=128
part pv.32 --size=12048 --asprimary
volgroup VolGroup00 --pesize=32768 pv.32
logvol / --fstype ext3 --name=LogVol00 --vgname=VolGroup00 --size=12032

im using a xen management script but its not working without this Partition
My problem is how to do it via GUI the config.

System: CentOS
Method: Remote Install .pxe



Thank you very much
I hope that someone helps me out to get my Xen Working.
