Xen users - Feb 2009 - Debian 4.0 packaged Xen and running an unmodified Linux guest

Hi all, 

I have a Xen VMM based on version 3.0.3-1 running happily on Debian 4.0
"Etch". It is running several Debian domUs just fine.

What I would like to do is install and run a custom Linux distro, which
I have as an ISO file, as an unmodified guest.

I''ve seen several HOWTOs for instructions but it seems I am missing
several components such as the "device_model" file /xen/bin/qemu-dm
and
the kernel "/usr/lib/xen/boot/hvmloader". I am unsure where to source
these from.

Has anyone done this with just the Debian Etch Xen packages? I''m happy
for someone to tell me to hop onto the cluebus and read the docs but a
pointer to which docs would be useful :)

This chap here appears to have has done it by compiling his own Xen but
I would like to stick with the repository packages if I can:

Our Xen install info:

One other thing worth mentioning, the Xen dom0 kernel is
"2.6.18-4-xen-amd64" and the system CPU is "model name	: Intel(R)
Xeon(R) CPU           X3210  @ 2.13GHz" but does support the
"vmx" flag.
So a mix of AMD and Intel - is this anything to worry about?

Many thanks!
Im

First: enable virtualization extension support on bios.
Not all kernels show you this flag when you boot Xen when you enable it on bios.
