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:
user@hostname:~$ ls -lA /usr/lib/xen-tools/ubuntu.d/

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:
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:
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:

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".
