I'm embarrassed to say I think I know the problem, and it's not the
first time I've been bitten by this.
I created two small boot partitions, along with the raid array, but I
don't mount them from fstab. So the kernels in /boot are not the booting
kernels at all; what I should have done was mount both boot partitions
(at /boot0 and /boot1, for example) and then copy dom0.gz and xen.gz to
these mounted partitions.
I now have no way of checking whether or not this is the solution but
I'm pretty sure it is. I will try it as soon as my new server is
Thank you for your help.
