Currently, only a very small subset of the hypercalls are exposed to HVM guests. Was this set arrived at based on what was required to host para-virtualized drivers? Or are there other considerations that governed this decision. Specifically, would there be any objections to opening up more hypercalls to HVM guests.

They need auditing one-by-one, and also we have to worry about 32-on-64 compatibility issues (which will be helped by the PV PAE-on-64 work by Jan Beulich). We do plan to broaden the supported set of hypercalls (memory_op for example).
