Answers:
恐怕您不能在仅命令行的来宾上拥有共享剪贴板。
这是因为TTY并未真正创建供访客添加使用的适当剪贴板，因此您需要完整的GUI。
使用SSH从主机登录到来宾会更好。这样，您可以使用SSH客户端的功能（例如Putty）共享剪贴板。
可以做到的。我无法双向处理以下内容，但是Host to Guest（即将内容粘贴到文本控制台中）确实有效。以下说明适用于CentOS 5/6/7，但是它们的类似机制也适用于其他口味。
这将使X11剪贴板与gpm剪贴板保持同步。如果将“共享剪贴板”设置配置为“从主机到来宾”，则当主机剪贴板发生更改时，VirtualBox将更新X11剪贴板...修补的gpm然后将使用xclip将X11剪贴板数据拉入gpm剪贴板...然后可以将其粘贴鼠标中键。
可以共享“主机到访客”剪贴板以在服务器/控制台模式下工作。目前，“来宾托管”共享不起作用，可能是由于VBoxClient和Xvfb之间存在问题。
百胜安装Xvfb
挂载/ dev / cdrom / mnt
/mnt/VBoxLinuxAdditions.run
以/ usr / local / bin / xclip 下载，编译和安装xclip（http://sourceforge.net/projects/xclip/）。
下载最新的gpm源，并进行以下更改以对其进行修补。
将二进制文件安装为/ usr / local / bin / xclip-gpm。
这是Alex Efros的修补程序的更新版本（http://powerman.name/patch/gpm.html）。

我找到了一种将Windows剪贴板内容导入来宾Linux的round回方式，在这里共享它，以防其他人发现它有用：
首先，安装非常有用的ClipX（我很幸运，因为我已经安装了ClipX，并且在遇到此复制粘贴问题时出于其他原因刚刚浏览了其插件列表。）
还要ClipX DiskLog Plugin 1.2从同一页面安装
右键单击系统托盘中的ClipX图标，Configure然后选择文件的位置（注意：此文件将存储您所有剪贴板内容，选择一个私有位置和/或定期清除它），例如D:\Personal\clipboard\clip.txt
在Linux guest虚拟机上，安装Virtualbox Guest附加组件（其他地方提供了说明，并且X在安装过程中忽略了与任何相关的错误，所需的“共享文件夹”功能仍然可以使用）
在您的Virtualbox中，转到Devices->Shared Folders，添加上面的文件夹D:\Personal\clipboard\并为其命名，例如clipboard（您可能希望在继续操作之前重新启动客户机，除非您希望此时手动安装驱动器）
现在在您的.bashrc（或.bash_aliases您愿意的话）中创建一个别名
alias winclip='tail -n 1 /media/sf_clipboard/clip.txt'
每当您希望在命令行上使用当前Windows剪贴板内容时，只需$(winclip)在该位置使用
这看起来像很多步骤，但是仅需几分钟，并且避免了运行VM服务器和Putty客户端以及ssh使用此简单功能的麻烦。我还没有找到一种双向的方法，欢迎提出建议！
这就是我为在没有Gnome桌面环境的情况下安装的Debian 7.4.0服务器启用双向剪贴板支持的方式。我正在使用VirtualBox 4.3.6。
安装并启动X服务器：
apt-get install x-window-system-core && startx
安装Xclip以支持剪贴板
apt-get install xclip
安装工具，以便Virtualbox可以构建来宾添加
apt-get install bzip2 build-essential linux-headers-`uname -r`
挂载来宾附加映像并安装附加
mount /dev/cdrom /mnt && bash /mnt/VBoxLinuxAdditions.run
最后使用重新启动debian shutdown -r now。
