virtualbox - VirtualBox VBoxManage 可以即时添加/删除共享文件夹吗？

Question

当我尝试向我的 VirtualBox 添加/删除共享文件夹时出现此错误:

~$ 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

当我停止机器、操作共享然后再次启动机器时，它会起作用。它也适用于 VirtualBox UI，但我想编写这些操作的脚本。

在 Mac OS Yosemite 上运行 VirtualBox 5.0.12。该盒子配备了 docker-machine。

正如“socratis”在 Virtual Box Forum 中指出的那样，方法是使用 --transient 标志:

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

当使用 --transient 时，映射不会在 VM 重启后持续存在。

VirtualBox documentation也提到了这一点:

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.
