As syscalls can be located with the help of symbol files, is it possible to
do it to hypercalls too?

could you explain that in detail? As syscall tracing, we usually locate the
kernel module first, then find the address of specific syscall function in
that module with the help of symbol files. How could this be applied to
hypercalls then?

All right, what is the base address of hypercalls table? And which file
contains the offset of each hypercall?

Did you at least _try_ to find the answer yourself, e.g. by
grep-ing the
I've read the hypercall related code, such as entry.S hypervisor.h ,etc.
But the problem is that hypercall functions are implemented in different
files while linux package syscalls into glibc and windows ntoskrnl. There
is a hypercall table defined in entry.S. But I havn't found any offsets

grep-ing the hypervisor source for some obvious strings?
