   Does XEN provide some CPU counters, so that I can count the number of instructions executed by a user level process in one of the domains?
Also, I have a user level process P1 executing on domain 1 and another user level process P2 executing on Domain 0. P1 needs to call some APIs (these APIs have incoming and outgoing parameters) exposed by P2. Is there any other way to achieve this communication apart from using RPC and sockets?
