Thank you very much! I'll try this. BTW is it required to do this for every 
module with HVM hypercalls or there is some shared initialization code in HVM 
guest (Linux) similar to one used in paravirtualized guests?

If it's supposed to be in a module, is there any good example I can look at?

AFAIK hypercall_page is being initialized on Xen side with appropriate 
vmcall/vmmcall code. Is this CPUID mechanism a standard way to obtain 
hypercall_page reference on HVM domain?

What kernel are you working with? There's already code to implement pv-on-hvm support for various recent pvops kernels, so you can just base your work on those.
