I upgraded the dom0 Kernel. And yes, it is modified (by openSuSE) for XEN.

My poblem is, that I need to have to modfiy the virtual guests (i.e.
copy the correct kernel modules into their filesystems).
My question is, if there is any way to get around this (as we're plan to
use various instaces of XEN guests without touching them at every update)?
