All the commands below are executed from the root shell. I this howto "chroot" is used to enter as NEWROOT, a BUILD-VE must not be created!== Manual Instructions ==
VE0_# chroot /vz/template/$DIST/$VERSION/$ARCH/The instructions below are informative but out of date and likely '''will not''' work with an Arch system built after 2011.
=== Prerequisites ===
=== setting DNS server ===I used a modified archbootstrap script which can be found at http://forzza.systs.org/openvz-misc/{{Note | This link is currently broken}}{{Note | One can use mkarchroot (provided by devtools) in place of archbootstrap if building the template on Archlinux. See [[Talk:Archlinux_Template_creation|Disussion]] for a bash script to do this. The script makes it easy to build an image on an arch machine, then copy the zipped template over to your VZ host.}}
For the chroot BUILD we also need to specify a DNS for itEdit settings of script "archbootstrap" :
BUILD_# mv /etc/resolv.conf.pacorig /etc/resolv.conf ARCH="i686" IGNORE="rp-pppoe ppp wireless_tools xfsdump xfsprogs reiserfsprogs lshwd usbutils pciutils pcmciautils module-init-tools mdadm mkinitcpio libusb jfsutils lvm2 lilo cryptsetup device-mapper dhcpcd hwdetect dmapi gen-init-cpio grub" umark PACMAN_OPTS (remove '#')
=== update and install packages ===
Update (sync) pacman cache and update installed packages{{Note|I suggest to place the build for OpenVZ templates to /vz/template/, schema: /vz/template/$DIST/$VERSION/$ARCH/}}

=== fix /etc/inittab = setting DNS server ====
Remove getties from inittabFor the chroot BUILD we also need to specify a DNS for it:
