I am running virtualBox on Ubuntu 16.04

When I was in command line input：sudo VBoxManage storageattach Windows7 --storagectl SATA --port 0 --device 0 --type hdd --medium "/home/luxixian/WIN7_X64_2017.iso"


the log show me this:

VBoxManage: error: Could not find a registered machine named 'Windows7'
VBoxManage: error: Details: code VBOX_E_OBJECT_NOT_FOUND (0x80bb0001), component VirtualBoxWrap, interface IVirtualBox, callee nsISupports
VBoxManage: error: Context: "FindMachine(Bstr(a->argv[0]).raw(), machine.asOutParam())" at line 325 of file VBoxManageStorageController.cpp



who can help me ? thank you very much.

The error ( Could not find a registered machine named 'Windows7' ) is a basic as it gets. There is no guest called Windows7 registered. Is the host a server with no GUI?

Type VBoxManage list vms in a terminal to see if one exists and what it is actually called.

Also don't run VBoxManage with 'sudo', it needs to run with your normal user rights. The root user doesn't have your virtual machines.
