This is not at all true. There is no relationship of this sort between
Xen releases and guest kernel versions.

The guest visible hypervisor ABI has been stable since (IIRC) Xen 3.0.0
and Xen upstream maintains backwards compatibility for guest visible
interfaces -- if an old guest was broken by a hypervisor update then
this is most likely a bug.

On the other hand, the Xen enabled kernel in Lenny turned out to be a
bit of a disaster and I could well imagine that the new hypervisor/tools
are simply exposing a prexisting bug in that kernel. Due to that and the
fact that Lenny is now oldstable you may find there is not much interest
in tracking this issue down.

Ferenc should definitely make sure you are running the most recent Lenny
kernel though, the bug report doesn't include the version of this
package AFAICT. Failing that running a Squeeze kernel from the
lenny-backports suite is a good option IMHO.
