Thanx George.

Yes, am looking into xen-2.0. "struct vcpu_info" is not present there.

Actually am doing a project in which i need to provide a functionality similar to pushing the address of cr2 onto the stack.

Also, how can I avoid the use of fast handlers?...I need to perform some checks inside xen before transferring control to the guest OS for each trap.

Should I modify the "set_trap_table" hypercall for that??

It's worth a shot looking there.  Certainly 3+ will have it for sure.

Is there a particular reason you want to avoid that struct?
