Hi all,
My guest OS is of HVM.I want to  pass a parameter to the VMM .As far as I know ,there is a hvm_op in VMM to deal with hypercall from the guset OS of HVM.but is there any function in the guest kernel that i can call to pass parameters.It seem that in HVM,there is no function supporting for  hypercall  directly.Then  what can  I  do?
Thank you.

Wei Wang.
