So you have the latest version included in *Lenny*, which is already
pretty old. 

The Xen hypervisor in lenny is version 3.2, which is pretty old. Like said, 
the newest stable upstream Xen version is 3.4.2. Also the Xen
dom0 kernel in lenny is based on some early opensuse kernel snapshot,
and it's known to have problems/bugs.
