I'm assuming it's your Dom0 that is not booting correctly - can you confirm
that? Typically, this should 'just work' and as the Dom0 is the privileged
domain it's not using the xennet and xenblk drivers but actually uses the
real hardware.

Using openSUSE 10.3 (especially for a newbie) you're far better off using the
version(s) of Xen that ship with the distribution rather than those available
via tarballs at xensource.com or xen.org (although there's no reason why they
won't work).

Can you confirm that you've got the Xen enabled kernel installed? This should
have quite a few more sub-directories in this directory than the two you
mention.

This looks like some sort of custom set up, as the initrd normally doesn't
have the .img extension if it's been installed from the distribution. Your
also trying to boot a kernel called vnlinuz... is the n here just a typo?
My installation of openSUSE 10.3 is using a 2.6.22 kernel series - how come
yours is on the older 2.6.18 series? (This looks suspiciously like a SLES 10
kernel family - is that what you downloaded and installed from xen.org
maybe?)
