Yes, unfortunately we are - unlike the Linux kernel which maintains syscall
compatability forever, the Xen project does not maintain any stability
in its hypercall ABI breaking stuff at will during development :-( DV is
currently working on updating libvirt so that it will work with the new 
hypercall ABI (detecting which version to use at runtime, so we are still
compatible with all old ABIs too). I expect this work to hit CVS in the
near future.

It will work on any xen-unstable.hg snapshot upto the changeset which 
broke the hypercall ABI compatability.
