I don't have personal experience with Lenny, perhaps the xen-users list does.

I see Debian does have kernels:

Anybody running Xen + Dom0 kernel successfully on Lenny?

I use Lenny as a Dom0 with the "stock" xen kernel but use 3.4.3 hypervisor rather than the one in the repos. I would recommend you run the 64 bit version because it is more stable if your hardware supports it. You can compile and install the hypersior fairly easy. You can use the instrustions from the 4.0 hypersivor to compile the 3.4.3 hypersivor. They can be found at:


You can download the 3.4.3 code from:


When you do the compile just do:

make xen
make tools
make stubdom

make install-xen
make install-tools
make imstall-stubdom

I would avoid doing a full on make world as this compiles a kernel, hypervisor and tools.

If you install xen using:

apt-get install xen-linux-system-2.6.26-2-xen-amd64

Then you will need to run update-grub after you do the install so the new hypervisor is configured correctly in grub.

If you can start with a clean install of Lenny and go from there. I would load just the hypervisor:

apt-get install linux-image-2.6.26-2-xen-amd64

And then add the peices you need from there. I would also use the backports for Leeny for more current packages:


Like libvirt-bin, xen-tools.

The only issue I have run into with this is I haven't been able to get the GUI desktop to run with the xen kernel. I don't need this on my servers so it's not an issue for me, maybe someone can give you a pointer to get this running.

Getting a working (stable) Lenny based xen server setup can be a lot of work. I haven't found a linux distro yet that had all the pieces I required included but that is the nature of the beast and is a function of my own needs and not really a limitation of the linux distro's I tried.

Good luck and if you have any questions you can contact me off list and I will try to help time permitting.

Hi Todd,

I have installed Debian Lenny, and followed some of the instructions at:

Install Lenny. Finish the installation as you would normally do
apt-get install install xen
apt-get install xen-utils
apt-get install xen-tools

I am stumped about what to do at step 5

install a xen dom0-capable kernel

I downloaded the image from:

But I do not know how to install it.
I tried dpkg -i, but it reports unsatisfied dependencies.
I tried to follow down all the dependencies, but don't really know how.

So, that is where I am now stuck.
Can you recommend next steps for me?

Hi Todd,

Thank you for your fast response.
Debian Lenny was my first candidate.
I installed it (many hours)
then acquired and compiled xen
and then booted to that kernel
and that was the attempt that led to
xend failing for lack of some resource.

I will try it again, given your advice but
I fear I will waste another many hours
and end up with no better results.
A little bit of steering by you
would make a huge difference to me.

Hi list readers,

I am an experienced developer with only nominal configuration talent.
These days, mostly I use ubuntu linux, but have used Debian, WhiteBox,
CentOS, RH, Fedora.

I have been using Sun VirtualBox to very great effect and hope for
by installing and using xen.
I also intend to use Dom0 exclusively as a host, and not install any
Instead, I expect to do all my development and package downloads onto

I wish to do a fresh install of a xen linux onto a brand new 1TB disk
on my
IBM Thinkpad T61 laptop.
My intention is to generate file-based virtual machines that I can copy
make new instances.
I am expecting to use HVM rather than paravirtualization and files
of logical volumes.

So far, I have tried it three times, once with Debian Lenny, and twice
ubuntu Maverick Meerkat.
Every time I encounter show-stopper problems during compiles or xend
on execution.
I do not know if I have identified a solid recipe to follow, or whether
choices are bad.

What I request is start to finish step by step instructions (preferably
ubuntu or Debian).
I am willing to back off on the Dom0 OS to an earlier ubuntu or Debian.
All I want is to generate a solid baseline xen system that is as
and simple as possible.

I will start from scratch with a clean disk, if I can only get
that lead to a working host.

Please help by providing a single complete clean instruction list to

These links might help.


Post questions if you get stuck on anything. ##xen on freenode is also
a place to ask questions.

Hope that helps.
