Hi there,

Sorry I'm not sure if this is the correct mailing list for this question - I 
already tried tools and didn't get any replies - please let me know if I should 
repost somewhere else.  Anyways, I've been using some of the API's in libxc to 
look at memory of a guest, set single stepping, read registers, etc....   using 
the xc_* functions.  This library is awesome.

I was wondering - Does anyone know of a way using libxc or some other api's to 
set and respond to hardware (not software!) breakpoints on a guest vm?  If so 
are there any examples out there?

Note - I'm NOT talking about connecting to a guest with a gdb client - I want 
to do this programmatically.

Thanks!!!
-Bob
