Correct. The fact that the dhcp client works but the networking doesn't, seems
very strange even to me actually.

Of course! ;-)

OK, I did it. Anyway, as far as I can see, vmlinuz is only a symbolic link.
here's the ls -l /boot after the kernel-xen installation:

If I boot using these entries:
kernel /boot/vmlinux-2.6.37.6-0.9-xen
root=/dev/disk/by-id/ata-QEMU_HARDDISK_QM00001-part2
resume=/dev/disk/by-id/ata-QEMU_HARDDISK_QM00001-part1 splash=silent
quiet showopts vga=0x314
    initrd /boot/initrd-2.6.37.6-0.9-xen
(I gunzipped the vmlinux file)
It still says: Error 13: Invalid or unsupported executable format.
Same thing if I use the .gz file of course.

With the 2.6.37 kernel booted:
PCI_CLASS=30000
PCI_ID=1013:00B8
PCI_SUBSYS_ID=5853:0001
PCI_SLOT_NAME=0000:00:02.0
MODALIAS=pci:v00001013d000000B8sv00005853sd00000001bc03sc00i00

Yes, I see those lines.

The package installation begins, but it's very slow and it blocks.

I mounted the ISO image as loop in /var/www/localhost/htdocs/suse11. Maybe
the memory is going to run out if I launch both the dom0 and the mount
-o loop and
also the domU start.

The installer got frozen. No possibility to go ahead. Sometime even my dom0
got blocked, so I have to use sysrq magic keys to reboot. Maybe it's
due to a memory
issue, even if the system is still accessible via ssh and is "alive".
It seems the
hypervisor die. Every xl command stucks without giving any reply in the console.

Thanks a lot again,
