Install debian etch as host (dom0)
I prefere setup with LVM2 enabled:

vhost10:~# pvdisplay

#got a hardware virtualization enabled cpu ? install:
apt-get install xen-ioemu-3.0.3-1

#optional: if you want to provide redhat/centos/suse you need to install rinse:
apt-get install rinse

# Get debootstrap from ubuntu and install under debian, eg:

wget http://archive.ubuntu.com/ubuntu/pool/main/d/debootstrap/debootstrap_1.0.7_all.deb
dpkg -i debootstrap_1.0.7_all.deb
rm debootstrap_1.0.7_all.deb

#vi /etc/modules  and append:

#  loop max_loop=255
