Hello Shane ! Yes, all packages installed. Is Xen-4.0-amd64.gz a bootable kernel ? Right now, the system si booting this one : vmlinuz-2.6.32-5-xen-amd64 and this initrd: initrd.img-2.6.32-5-xen-amd64 as you can see on the menu.lst file.

Xavier,
First place I would start it running the following :

aptitude search xen-utils
Make sure xen-utils is installed (i in the far left column)

aptitude search qemu-dm
again making sure the package is installed.

If both packages are installed I would make sure you are booting off the the version that says :

Debian GNU/Linux, with Linux 2.6.32-5-xen-amd64 and XEN 4.0-amd64

Hello ! I'm trying to run Xen on a EC2 AMI

debian-6.0-squeeze-base-x86_64-20110417 (ami-35b68141)

Following this how-to http://www.howtoforge.com/paravirtualization-with-xen-4.0-on-debian-squeeze-amd64

After installing the packages, I get :

uname -a
Linux ip-10-241-22-60 2.6.32-5-xen-amd64 #1 SMP Tue Mar 8 00:01:30 UTC 2011 x86_64 GNU/Linux

uname -r
2.6.32-5-xen-amd64

Then I do : mv /etc/grub.d/10_linux /etc/grub.d/50_linux
update-grub2

After I reboot but I get this when calling xm :

xm dmesg
WARING! Can't find version 3.4 of xen utils, fallback to default version!
Error: Unable to connect to xend: No such file or directory. Is xend running?

When I execute xend I get :

xend
WARING! Can't find version 3.4 of xen utils, fallback to default version!
ERROR Internal error: Could not obtain handle on privileged command interface (2 = No such file or directory)

xc = xen.lowlevel.xc.xc()
xen.lowlevel.xc.Error: (1, 'Internal error', 'Could not obtain handle on privileged command interface (2 = No such file or directory)')

Does this has to do with the kernel I'm booting ?

My /boot looks like this :

System.map-2.6.32-5-xen-amd64

initrd.img-2.6.32-5-xen-amd64

config-2.6.32-5-xen-amd64

vmlinuz-2.6.32-5-xen-amd64

grub

xen-4.0-amd64.gz

And my menu.lst looks like this :

#
# DO NOT EDIT THIS FILE
#
# It is automatically generated by grub-mkconfig using templates

# from /etc/grub.d and settings from /etc/default/grub
#

### BEGIN /etc/grub.d/40_custom ###
default 0
timeout 1
title 2.6.32-5-xen-amd64
root (hd0)

kernel /boot/vmlinuz-2.6.32-5-xen-amd64 root=/dev/xvda1 ro
initrd /boot/initrd.img-2.6.32-5-xen-amd64
### END /etc/grub.d/40_custom ###

I have been trying to get around this but ... nothing works !

Any help would be much appreciated, thanks in advance !
