oops when access xenstore in hvm guest
...PFN;     if ( hypercall_hvm_op(HVMOP_get_param, &param) )         BUG();     xenstore = (void *) (unsigned long) (param.value << PAGE_SHIFT);     param.domid = DOMID_SELF;     param.index = HVM_PARAM_STORE_EVTCHN;     if ( hypercall_hvm_op(HVMOP_get_param, &param) )         BUG();     xenstore_event = param.value;     I get the xenstore ring whose address is 0xfeffc000, and event channel port 2, but when i read the xenstore->req_prod, it came to "unable to handle kernel paging request at virtual address feffc804", i am using xen-3.4, any idea?Thanks.   _______________...
