Currently none of the hypercalls are implemented. You'll get a guru 
meditation with (VERR_GIM_IPE_3) if the guest tries to do hypercalls but 
we had to expose availability of hypercalls as Windows expects it to be 
there even when it actually doesn't use it. This was needed to get other 
more vital things to work like TSC rate reporting, etc.

The basic framework is there, but at the moment, this is unreleased 
trunk code - so it's work in progress. Out of curiosity, what hypercall 
are you trying to implement by the way?

Ram.
