Ian and Keir Do you have more suggestion beside the seperate hypercall table for para-driver? some other possible alternative: 1. move the change to grant_table.c to vmx.c, and use a virtual_device_op to setup up the grant table share page so that grant_table.c don't need change. 2. move the logic of copying hypercall paramter to share page to hypervisor instead of in guest. then share page is not needed. but the copy overhead maybe bigger because each copy need to map.
