It doesn't make any difference whether you use debian, centos or some
other OS. You need to create the initrd in the host-machine, using the
xen-kernel that you've got there. So, if you're using sles, it should be
something like this:
mkinitrd somewhere/initrd-$ver-xenU $ver-xen --with=blkfront
[$ver would be something like 2.6.16.33, matching the version of your
xenified linux kernel].
The location of "somwhere" could be /boot, but doesn't have to be.

You don't need anyting in the guest's boot directory, as the kernel and
initrd are loaded from Dom0's file-system.
Whether you still have something in /boot in the guest obviously depends
the way it was installed and if the install process decided to stuff
something in /boot for some reason (e.g. it ALWAYS writes some files to
/boot, whether it's necessary or not).
