Vagrant Windows 7主机上Debian guest中的CentOS guest:“；VT-x不可用（VERR_VMX_NO_VMX）"；

我已经在Windows 7上安装了VirtualBox 5.1。 在那里，我设置了一个来宾操作系统Debian（64位）。 对于这个来宾系统，我在“系统-加速”菜单中选中了“启用VT-x/AMD-V”和“启用嵌套分页”框，“半虚拟化接口”设置为“KVM”

现在，我尝试在Debian guest操作系统中部署CentOS（guest）系统（按照安装Apache Metron开发环境的说明），使用VirtualBox 5.0作为Vagrant的提供者

我运行：

vagrant up

并接收以下输出：

                 There was an error while executing `VBoxManage`, a CLI used by Vagrant
                 for controlling VirtualBox. The command and stderr is shown below.

Command: ["startvm", "34769275-58df-4c89-af8d-d1cb3e538dc9", "--type", "headless"]

Stderr: VBoxManage: error: VT-x is not available (VERR_VMX_NO_VMX)
VBoxManage: error: Details: code NS_ERROR_FAILURE (0x80004005), component ConsoleWrap, interface IConsole

有人知道发生了什么事吗

注意：这里的许多帖子都建议关闭Hyper-V。实际上，我曾在Dell上尝试过关闭Hyper-V，但在BIOS中找不到它。我也不认为这会有帮助，因为问题出在客人的客人身上

事实证明，VirtualBox内部的VirtualBox不受支持（目前）：
