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, matching the version of your
xenified linux kernel].

The location of "somwhere" could be /boot, but doesn't have to be.

does this mean, that I only have one initrd on my host (dom0) for all
my guest systems(domU)?
