VirtualBox VBoxManage可以即時添加/刪除共享文件夾嗎？

Question

當我試圖添加/刪除共享文件夾到我的VirtualBox的我收到此錯誤：

~$ VBoxManage sharedfolder add dev --name srv --hostpath "/my/local/path" 

VBoxManage: error: The machine 'dev' is already locked for a session (or being unlocked) 
VBoxManage: error: Details: code VBOX_E_INVALID_OBJECT_STATE (0x80bb0007), component MachineWrap, interface IMachine, callee nsISupports 
VBoxManage: error: Context: "LockMachine(a->session, LockType_Write)" at line 1012 of file VBoxManageMisc.cpp 

它的工作原理，當我停下機器，操縱股價，然後重新啓動機器。它也適用於VirtualBox用戶界面，但我想編寫這些操作腳本。

在Mac OS Yosemite上運行VirtualBox 5.0.12。該盒子配備了docker-machine。

截至Virtual Box Forum注意到「socratis」，要做到這一點的方法是使用--transient標誌：

 ~$ VBoxManage sharedfolder add dev --name srv --hostpath "/my/local/path" --transient 

當使用--transient，映射不會在虛擬機重新啓動持續。

的VirtualBox documentation提到了這一點，以及：

There are two types of shares:

VM shares which are only available to the VM for which they have been defined; transient VM shares, which can be added and removed at runtime and do not persist after a VM has stopped; for these, add the --transient option to the above command line.
