A quick search indicates that there is some HVM hypercall code:

http://xen.markmail.org/search/?q=hvm+hypercall
http://xen.markmail.org/search/?q=hypercall_hvm_op#query:hypercall_hvm_op+page:1+mid:bozac75eaw4jrgof+state:results
http://lxr.xensource.com/lxr/source/xen/arch/x86/hvm/hvm.c

I don't know the details. You may considering taking a look at:
