I think the problem lies in the initrd used to boot the hypervisor
(/boot/initrd.img-2.6.18-4-xen-686).

I uncompressed it (using gunzip then cpio -i --make-directories), and
found out the following :

hortense:~/initrd.img-2.6.18-4-xen-686.out# ldd bin/sh
        linux-gate.so.1 =>  (0xffffe000)
        libcrypt.so.1 => /lib/libcrypt.so.1 (0xb7f9a000)
        libm.so.6 => /lib/libm.so.6 (0xb7f73000)
        libc.so.6 => /lib/libc.so.6 (0xb7e30000)
        /lib/ld-linux.so.2 (0xb7fdb000)

but :

hortense:~/initrd.img-2.6.18-4-xen-686.out# ls -l lib
total 1212
drwxr-xr-x 3 root root   4096 2007-06-08 12:23 i686

-rw-r--r-- 1 root root  23264 2007-06-08 12:23 libvolume_id.so.0
drwxr-xr-x 3 root root   4096 2007-06-08 12:23 modules
drwxr-xr-x 2 root root   4096 2007-06-08 12:23 udev

So there's no /lib/libcrypt.so.1

Actually, I find it in :
hortense:~/initrd.img-2.6.18-4-xen-686.out# ls -l lib/i686/nosegneg/
total 1496
-rw-r--r-- 1 root root   21908 2007-06-08 12:23 libcrypt.so.1
-rw-r--r-- 1 root root 1327616 2007-06-08 12:23 libc.so.6
-rw-r--r-- 1 root root    9684 2007-06-08 12:23 libdl.so.2
-rw-r--r-- 1 root root  153424 2007-06-08 12:23 libm.so.6

Soo... I think there's something wrong with the initrd generation for
the xen hypervisor :(

I'm gonna try and symlink so that the libcrypt.so.1 gets available in
lib and see if this solves the problem... however I'm not sure the
nosegneg is right for starting the dom0...

Hope this helps.
