ok, now I have a tricky question. Do I need to have both kernels installed? What if I remove the standard kernel, and only keep the xen kernel?

Well, I kept the non-xen kernel around in case the automatically starting xen domU's would crash the system. In that case, I can easily start the box with a non-xen kernel to resolve the problem.

But technically, I see no reason to keep them around.


That's what I'm fearing as well. What if the Xen kernel crashes. In this case I'd still need to drive out to the DC - which I don't quite want. I guess I'll just exclude the normal kernel from the updates as you suggest. P.S. Do you know if one could set a backup / fail-safe kernel in grub, which can automatically boot if thew default kernel gives problems?
