===== setup cobbler-services on the cobbler-vm =====
<code>
# I will use the http-export from the host also for the client-installs:
host$ echo '/mnt/centos 10.0.22.0/24(async,rw,no_subtree_check,no_root_squash)' >>/etc/exports
host$ /etc/init.d/nfs-kernel-server reload

# from now on at the cslave vm:
mkdir /mnt/centos
mount 10.0.22.1:/mnt/centos /mnt/centos

# lets setup epel-repos additionally:
rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5
rpm -Uvh http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-3.noarch.rpm
yum install -y cobbler dhcp xinetd

chkconfig tftp on
service iptables stop; chkconfig iptables off
sed -i 's,enforcing,disabled,' /etc/sysconfig/selinux
setenforce 0

cd /etc/cobbler
vi settings
# manage_dhcp: 1
# server: 10.0.22.7 # ip of the cobbler-vm
# next_server: 10.0.22.7 # ip serving the tftp, here the host-linux

vi dhcp.template
# edit the subnet-section to look like this:
------------

     option routers             10.0.22.1;

# i also had to remove these 3 lines (dhcpd didnt like the resulting output):
------------
        #if $iface.hostname:
            hostname $iface.hostname;
        #end if
------------

service cobblerd start
cobbler sync
service dhcpd start
service httpd start
service xinetd start
for i in cobblerd dhcpd httpd xinetd; do chkconfig $i on; done

# now import the first distro
cobbler import --path=/mnt/centos --name=centos --available-as=http://10.0.22.1/centos

# and lets set the sample kickstart template
cobbler profile edit --name=centos-i386 --kickstart=/var/lib/cobbler/kickstarts/sample.ks

# now we are ready to cobbler-boot a client.
