you need a mutable IMachine instance, refer to following code:
 
// delete a vbox vm given the vm name
HRESULT DeleteVBoxVM(IN PWSTR vmname)
{
HRESULT rc;

rc = CreateVBoxCOM();
if (rc)
return rc;
IMachine *machine = NULL;
ISession *session = g_pSession;
IMachine *pMutableMachine = NULL;
rc = g_pVBox->FindMachine(BStr(vmname), &machine);
if (SUCCEEDED(rc)) do { 
BSTR uuid;
machine->get_Id(&uuid); 

rc = g_pVBox->OpenSession(session, uuid);
CHECK_ERROR_BREAK(rc);
rc = session->get_Machine(&pMutableMachine);
CHECK_ERROR_BREAK(rc);
rc = pMutableMachine->DetachHardDisk(BStr(L"IDE"), 0, 0);
if (SUCCEEDED(rc)) {
/* commit changes */
rc = pMutableMachine->SaveSettings();
}
pMutableMachine->Release();
session->Close();
CHECK_ERROR_BREAK(rc);
IMachine *machine1 = NULL;
rc = g_pVBox->UnregisterMachine(uuid, &machine1); 
if (SUCCEEDED(rc)) {
machine1->DeleteSettings();
printf("Virtual machine '%ls' has been successfully deleted.\n", vmname);
machine1->Release();
}
} while (0);
if (machine)
machine->Release();
CHECK_ERROR(rc);
ReleaseVBoxCOM();
return rc;
}

after using addStorageController, I got this message: The machine is
not mutable (state is 1)

what does it mean?
