Fedora xen - May 2007 - pause installation, when selecting the compilation of the partition.

I want to done the construction of the mechanism of automatic
operation installation of XenU environment.
The command of virt-install is executed as description below

virt-install -r 256 -n system4 -f /var/lib/xen/images/system4 -s 4 -l
http://192.168.1.10/cdrom -x "text
ks=http://192.168.1.10/cdrom/ks.cfg" --nographics

And,Description of portion of the ks.cfg file is as description below.

clearpart --linux --drives=xvda
part /boot --fstype ext3 --size=100 --ondisk=xvda
part pv.2 --size=0 --grow --ondisk=xvda
volgroup VolGroup00 --pesize=32768 pv.2
logvol / --fstype ext3 --name=LogVol00 --vgname=VolGroup00 --size=1024 --grow
logvol swap --fstype swap --name=LogVol01 --vgname=VolGroup00 --size=272 --grow

It paused installation, when selecting the compilation of the partition.

Something probably is problem?
