Hey Meng,

We discussed about this issue before, here: 
http://lists.xen.org/archives/html/xen-devel/2014-09/msg02765.html

But, as far as it looks, the code we ended up merging still had the
issue (i.e., it did not have the hook implemented)!

I was working a bit on/off (for family reasons) in that period, so I
can't really tell how that happened. :-/
Not a big deal... this code is marked as experimental for a reason, but
it probably make sense to double check that anything else similar
happened, can you do that?

Thanks and Regards,
Dario
