Reboot your VPS and select the CentOS rescue image.

If you don't want to set up partitions (I didn't), just go ahead and make it ext3. 

# mkfs.ext3 /dev/xvda1

Mount the drive into /mnt 

# mount /dev/xvda1 /mnt
# cd /mnt

Download the install script and run it! 

# wget http://calimeroteknik.free.fr/arch-guide/install-chroot.sh
# chmod +x install-chroot.sh
# ./install-chroot.sh

(The install script chroots for you, when you're finished just type exit)


Remove the default kernel, as we're installing the Xen one. 

# pacman -Rsdn kernel26

To build the Xen kernel, you'll need to install the make, gcc, and patch packages from the repositories. 

# pacman -S make gcc patch

Download and untar the latest tarball of the kernel26-xen package. 

# wget http://aur.archlinux.org/packages/kernel26-xen/kernel26-xen.tar.gz
# tar -xf kernel26-xen.tar.gz
# cd kernel26-xen

You'll need to uncomment the following line from the PKGBUILD file. 

#pkgname=('kernel26-xen' 'kernel26-xen-headers') # Build kernel with a different name

Build and install the package. The first step will take a while, so grab some coffee and a scone. 

# makepkg --asroot
# pacman -U kernel26-xen-VERSION-x86_64.pkg.tar.gz
# pacman -U kernel26-xen-headers-VERSION-x86_64.pkg.tar.gz

Install grub 

pacman -S grub

Edit boot/grub/menu.lst and fill it with the following: 

timeout 5
default 0

# (0) Arch Linux
title  Arch Linux
root   (hd0,0)
kernel /boot/vmlinuz26-xen root=/dev/xvda1 ro console=/dev/xvc0
initrd /boot/kernel26-xen.img

Edit /etc/inittab and remove/comment these 

# -8 options fixes umlauts problem on login

c2:2345:respawn:/sbin/agetty -8 38400 tty2 linux
c3:2345:respawn:/sbin/agetty -8 38400 tty3 linux
c4:2345:respawn:/sbin/agetty -8 38400 tty4 linux
c5:2345:respawn:/sbin/agetty -8 38400 tty5 linux
c6:2345:respawn:/sbin/agetty -8 38400 tty6 linux

Uncomment this 

# Hypervisor Virtual Console for Xen and KVM
# h0:2345:respawn:/sbin/agetty -8 38400 hvc0 linux

Edit etc/locale.gen to suit your needs, then run locale-gen

This should fix everything complaining about time issues, though I have no idea if its the *best* way of doing it: 

# echo xen > /sys/devices/system/clocksource/clocksource0/current_clocksource

Install SSH and configure it (http://wiki.archlinux.org/index.php/SSH) 

# pacman -S openssh

Reboot your VPS and you should be good to go!
