I managed to install Xen on Debian etch just yesterday.  I used the
following packages:

xen-hypervisor-3.0.2-1-i386
   - Xen kernel and a lot of other stuff.

linux-image-2.6.16-2-xen-686
   - Kernel for your Dom0 and DomU's.

linux-modules-2.6.16-2-xen-686
   - makes /lib/modules/2.6.16-2-xen-686.
   - Then you can make your initrd with "update-initramfs -k
2.6.16-xen-686 -c -v"

Then you make your /boot/grub/menu.lst look like this...

## ## End Default Options ##

title           Xen 3.0 / XenLinux 2.6
kernel          /boot/xen-3.0.2-1-i386.gz dom0_mem=256M console=vga
module          /boot/vmlinuz-2.6.16-2-xen-686 root=*YOUR ROOT DEVICE* ro
console=tty0
module          /boot/initrd.img-2.6.16-2-xen-686
savedefault
boot

boot

### END DEBIAN AUTOMAGIC KERNELS LIST

That should get you booting into Xen at least.  If I were you, I'd just
start over if you can.

As for this:
"WARING!  Can't find version 3.0.2-3 of xen utils, fallback to default
version!"

After I got Xen installed, I was getting that error message every time I did
anything.  But then whatever I was trying to do would work perfectly anyway.
So I just wanted to get rid of the error message.  =P

I managed to find this script...

/usr/lib/xen-common/bin/xen-utils-version

And I commented out this line in it...  It's near the bottom of the script.

if [ -d "/usr/lib/xen-default" ]; then
   # [ "$QUIET" ] || echo "WARING!  Can't find version $VERSION of xen
utils, fallback to default version!" >&2
       echo "default"
    exit 0
fi

I know that's not exactly a "fix", but it works.

Hope that helps,
- GM

Subject: [Xen-users] xend failed (debian related)


Hallo again,

sorry for this Debian related problem, but I'm not on the Debian-list
and here are some good guys knowing the distribution.

I'm running debian/etch (testing) and made an Update today. Id installed
xen-unstable a new xen-enabled kernel and xend-Userspace related
packages. xen-unstable *is* unstable, it crashes when started more than
two domUs. So I want back. I installed the old kernel, the old
hypervisor (xen-3.0-i386.gz). But now, xend wont start:

WARING!  Can't find version 3.0.2-3 of xen utils, fallback to default
version!

But I don't know which package to downgrade to make that running.

Please help.
