Re: [Xen-users] paravirtulized suse 10.3 DomU over a suse 10.2 dom0

yes, i install it manually, my kernel/initrd are hand made from
kernel-xen- and install-initrd-1.0-228.i586.rpm in the
10.3 opensuse repository.
i have also tried to with kernel and initrd from the boot repository with
the same result.
i think my paths are correct, i used the same way to install 10.2 domU

With the yast install manager (ftp setup), same result, it fails after
dowload of the guest kernel).

About the net install boot cd, the minikernel on it is fine to launch the
install procedure, nothing happens just when the guest kernel is
downloaded (after you entered correct ip,gw,etc).

It seems to me like the paravirtualized 10.3 xen kernel doesn't
"recognize" well the virtualized hardware shown by 10.2 dom0 (or as you
say 10.2 doesn't know how to host the 10.3 one).

Any successfull attempt around ?
