I'm not completely sure, but while I was playing with Xen, I met this
error.
I happens when older xen-utils contact with newer hypervisor (or newer
utils with older hypervizor??? not sure).
Dirty solution: clear all signs of xen utils and xen themself from
system (not only uninstall, not only aptitude purge, but manual removing
any noties about xen from filesystem). (You can keep installation
directory).
After cleaning install required version, it shall works fine.
