Xen devel - Aug 2011 - mem_access

I heard the latest release of Xen includes an API called mem_access. If
I''m interested in analyzing memory accesses HVM guests are making,
would this api help? Also, I can''t seem to find any documentation on it
or where it is even located in the xen source tree. Can anyone point me in the
right direction?

Take a look at  ept_handle_violation() and tools/tests/xen-access in
the xen tree. This is a bare bone example of a mem_access event
listener. You can work your way back to the source from there.  BTW,
the API requires you to run on an Intel CPU with EPT support.
