Create a minimal Xen domU template for CentOS

Create partitions for the domU. With LVM:
lvcreate --size 6G --name LV-server-root VG00
lvcreate --size 512M --name LV-server-swap VG00
mkfs.ext3 /dev/VG00/LV-server-root
mkswap /dev/VG00/LV-server-swap
mkdir /mnt/server
mount /dev/VG00/LV-server-root /mnt/server
mkdir -p /mnt/server/dev /mnt/server/etc /mnt/server/proc /mnt/server/var/lock/rpm /mnt/server/var/lib/rpm /mnt/server/var/log
MAKEDEV -d /mnt/server/dev -x random
MAKEDEV -d /mnt/server/dev -x console
MAKEDEV -d /mnt/server/dev -x zero
MAKEDEV -d /mnt/server/dev -x null
mount -t proc none /mnt/server/proc
wget http://isoredirect.centos.org/centos-5/5/os/x86_64/CentOS/centos-release-5-0.0.el5.centos.2.x86_64.rpm
rpm --initdb --root=/mnt/server
rpm -ivh --root=/mnt/server --nodeps centos-release*.rpm
yum groupinstall Core --installroot=/mnt/server
cd /mnt/server
vi etc/fstab etc/resolv.conf etc/sysconfig/network etc/sysconfig/network-scripts/ifcfg-eth0 etc/hosts
(hint: make those files look similar to the ones in the dom0)
cd /; umount /mnt/server
edit your domU config file, in /etc/xen.
