This guide requires that you already have a CentOS 6 - If you do not have CentOS 6 installed, do it in KVM or VirtualBox or whatever you want.

At a CentOS 6 host as root do:
yum install yum-utils
yumdownloader centos-release.x86_64
mkdir -p /newroot/var/lib/
touch /newroot/var/lib/random-seed #without it, the initscript installation script will fail
rpm --rebuilddb --root=/newroot
rpm -i --root=/newroot --nodeps centos-release-6-3.el6.centos.9.x86_64.rpm
yum --installroot=/newroot install -y openssh-clients openssh-server yum yum-utils man wget sudo tar passwd
yum --installroot=/newroot clean all
ln -s /proc/mounts /newroot/etc/mtab
rm -f /newroot/dev/null
mknod -m 600 /newroot/dev/console c 5 1


Create /newroot/etc/fstab that looks like this:

 none /dev/pts devpts rw,gid=5,mode=620 0 0
 none /dev/shm tmpfs defaults 0 0

Edit /newroot/etc/sysconfig/init Change the line

 ACTIVE_CONSOLES=/dev/tty[1-6]

to

 ACTIVE_CONSOLES=

tar zcf /vz/template/cache/centos-6-x86_64.tar.gz -C /newroot .
