Xen on lenny fails after upgrade from etch?

["Oliver Schneider" <Borbarad@gmxpro.net>]

Hi,

when I upgraded a test system (from etch) to lenny, one of the upgrade steps related to Xen fails. Any ideas?

I tried reinstalling the packages, but get the same error all the time:
------------------------------
Starting XEN control daemon: xendTraceback (most recent call last):
