VirtualBox VBoxManage可以动态添加/删除共享文件夹吗？ [英] Can VirtualBox VBoxManage add/remove shared folders on the fly?

问题描述

当我尝试向我的VirtualBox添加/删除共享文件夹时，出现此错误：

When I am trying to add/remove shared folder to my VirtualBox I am getting this error:

~$ 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，操作共享然后重新启动机器时，它可以工作。它也可以在VirtualBox UI中运行，但我想编写这些操作的脚本。

It works when I stop the machine, manipulate shares and then start the machine again. It also works from the VirtualBox UI but I would like to script these operations.

在Mac OS Yosemite上运行VirtualBox 5.0.12。该框配备了 docker-machine 。

推荐答案

虚拟盒子论坛中的 socratis ，方法是使用-transient 标志：

As noted by 'socratis' at Virtual Box Forum, the way to do this is by using the --transient flag:

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

使用-transient 时，映射将不会在VM重新启动时持续存在。

When using --transient, the mapping will not persist over the VM restart.

VirtualBox文档也提到了这一点：

有两种类型的股票：

There are two types of shares:

VM共享，仅对已为其定义的VM可用；
瞬态VM共享，可以在运行时添加和删除，并且在VM停止后不会持久；为此，请在上述命令行中添加--transient选项。

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.
