=== PROCEDURE ===
Prepare your storage. You can use partitions, LVM volumes or simple file-based images. I choose file-based for the flexibility - for a real server you would NOT want to use a file-based because the IO sucks, use real partitions or LVM volumes.
Choosing a suitably large partition (/usr) I linked it into /opt/xen
  mkdir /usr/xen
  ln -s /usr/xen /opt/xen
Bootstrap Debian into a file-based image (note: this is a meager setup of 1GB root / and 128MB swap, you'll likely want much more for a real-world VM)
  mkdir -p /opt/xen/domains/vm01
  dd if=/dev/zero of=/opt/xen/domains/vm01/diskimage bs=1024k count=1024
  dd if=/dev/zero of=/opt/xen/domains/vm01/swapimage bs=1024k count=128
  mkfs.ext3 /opt/xen/domains/vm01/diskimage
  mkswap /opt/xen/domains/vm01/swapimage
  mkdir /mnt/disk
  mount -o loop /opt/xen/domains/vm01/diskimage /mnt/disk
  apt-get install debootstrap #If necessary
  debootstrap --arch i386 sarge /mnt/disk http://ftp.us.debian.org/debian
  chroot /mnt/disk /bin/bash
  cd /etc; vi hostname hosts resolv.conf
Add minimal entries as desired.
Create an ''/etc/fstab'' file
  /dev/sda1    /    ext3    errors=remount-ro    0    1
  /dev/sda2    none  swap    sw                    0    0
  proc          /proc proc    defaults              0    0
Logout and unmount ''/mnt/disk''
Now you can setup the first VM (aka vm01)
  cat > /etc/xen/vm01.cfg
  kernel = "/boot/vmlinuz-2.6.10-xenU"
  memory = 96
  name = "vm01"
  dhcp = "dhcp"
  disk = [ 'file:/opt/xen/domains/vm01/diskimage,sda1,w','file:/opt/xen/domains/vm01/swapimage,sda2,w' ]
  root = "/dev/sda1 ro"
Start it
  xm create vm01.cfg -c
  > Using config file "/etc/xen/vm01.cfg".
  > Started domain vm01, console on port 9601
Show it
  xm list
Attach to it (already done if used -c above)
  xm console vm01
Login as root (no password yet set), set the root password and update.
  passwd root
  /usr/sbin/base-config
  apt-get update
  apt-get dist-upgrade
