The loop driver is built in the kernel

hi,

as I got exactly the same problems as you I did some more research. I found this tutorial on a french site where the author uses a debootstrap backport. The article is in french, but you should get the details. I got some problems installing the package via apt on an amd64 box, so I downloaded the .deb manually and installed with dpkg. And guess what, with the new package debootstrapping hardy using xen-create-image works like a charm

Code:
xen-create-image --hostname=hardy --ip=xx.xx.xx.xx --size=10Gb --memory=256Mb --dist=hardy --mirror=http://archive.ubuntu.com/ubuntu/u.com/ubuntu/
ah, almost forgot - the golden link: http://howto.landure.fr/gnu-linux/de...bian-4-0-etch/

UPDATE: i wrote a short summary on my blog - http://maff.ailoo.net/2008/10/deboot...etch-xen-dom0/

cheers,
-- maff

The abovementioned command doesn't work here. It always complains;
Code:
...
 We'd expect the hook directory to be : /usr/lib/xen-tools/hardy.d

  Aborting.
..
ls -l /usr/lib/xen-tools/

drwxr-xr-x 2 root root 4096 2008-09-19 14:04 ubuntu.d
I tried before creating a symbolic link;
Code:
$ cd /usr/lib/xen-tools
$ ln -s ubuntu.d hardy.d
It didn't solve the problem. I suppose the problem coming from the version of dbootstrap on this Xen box.

It is in French, hardly for me to follow.

I have;

$ apt-cache policy debootstrap
Code:
debootstrap:
  Installed: 0.3.3.2etch1
  Candidate: 0.3.3.2etch1
  Version table:
 *** 0.3.3.2etch1 0
        500 http://ftp.au.debian.org etch/main Packages
        100 /var/lib/dpkg/status
installed on this box.

Would the new version;
Code:
landure.fr/pool/etch/debootstrap/debootstrap_1.0.10_all.deb
$ dpkg -i debootstrap_1.0.10_all.deb
be conflict with the running package?


TIA

I know this thread is old, but I just finished installing Ubuntu 9.10 (Karmic) on Xen as a guest, so I figured I should post what I had to do to get it that way. (Note: I can't boot... yet. Not sure what's wrong, is says "Error: Bootloader isn't executable"; either way, I managed to get past the stumbling block, as detailed below... perhaps this isn't the right way, but at least it did say that it installed, and not that it failed.)

First, I followed this tutorial, using image-based installations. I originally tried to install Ubuntu as a guest, but it was without success (I haven't tried again until just now, since Debian installed nicely). So, I had some "leftover breadcrumbs" to work off of for this attempt. I found this thread when I used Google for help with the "there is no hook directory for us to use" part.

Here's what I have in one of my directories:
Code:
user@hostname:~$ ls -lA /usr/lib/xen-tools/ubuntu.d/
total 68
-rwxr-xr-x 1 root root  774 2008-09-29 18:08 01-disable-daemons

user@hostname:~$
I believe I had just copied them over from one of the other folders - I didn't even have the computer in 2008, and that's the timestamp on the files - so they're probably the same ones that got installed along with the Debian stuff, just not quite in the same spot.

Partial "ls -lA /usr/lib/xen-tools/" output:
Code:
lrwxrwxrwx 1 root root   27 2010-01-01 22:06 karmic.d -> /usr/lib/xen-tools/ubuntu.d
.
.
.
drwxr-xr-x 2 root root 4096 2009-10-20 21:54 ubuntu.d
Again, in this next one, I think it's just a copy of the original for one of the other (older - I think "gusty") Ubuntu scripts; partial "ls -lA /usr/share/debootstrap/scripts/" output:
Code:
lrwxrwxrwx 1 root root    6 2010-01-01 22:12 karmic -> ubuntu
-rw-r--r-- 1 root root 5839 2009-10-20 22:00 ubuntu

Here's the final stuff in the shell:

Code:
user@hostname:~$ sudo xen-create-image --hostname=ubuntu-test-machine --role=udev --dhcp --dist=karmic

Looking back, I think the bootload issue was caused by me commenting out the kernel/initrd lines in the main xen-tools configuration file. I'm not sure, but I'm loopback-mounting, and chroot-installing a kernel, so I'll find out soon. Also, I think the kernel version needed is "2.6.31-16-generic".
