  I think that there is a mismatch between the nova plugins that you're 
using in dom0 and the nova code you're running in the DomU. So you need 
to update the content of /etc/xapi.d/plugins on dom0 according to the 
version you are running on the domU. On my installation I just copied 
the content of 
/opt/stack/nova/plugins/xenserver/xenapi/etc/xapi.d/plugins that is 
located on domU (I'm running devstack) to /etc/xapi.d/plugins that is 
located on dom0.

Hope this help,
