Hi, all I ran 'xl save -c cpf 4' on a running hvm domU. But the domU never resumed after command line exited.The system is just installed. So I doubted that anything I missed to prepare to make this command work. # xl -vvvvv save -c 2 cpf libxl: error: libxl_dom.c:1884:libxl__userdata_path: unable to find domain info for domain 2: No
