Windows 7主机上Debian guest虚拟机中的CentOS guest虚拟机：“ VT-x不可用（VERR_VMX_NO_VMX）” [英] CentOS guest in Debian guest on Windows 7 host: "VT-x is not available (VERR_VMX_NO_VMX)"

问题描述

我在Windows 7上安装了VirtualBox 5.1。
那里我设置了一个来宾OS Debian（64位）。
对于此来宾系统，我在 系统中选中了 启用VT-x / AMD-V 和 启用嵌套分页框-加速 菜单，并将 Paravirtualization接口设置为 KVM 。

I have VirtualBox 5.1 installed on Windows 7. There I have a guest OS Debian (64-bit) set up. For this guest system I have both "Enable VT-x/AMD-V" and "Enable Nested Paging" boxes checked in the "System - Accelaration" menu and the "Paravirtualization Interface" is set to "KVM".

现在，我正在尝试部署CentOS（访客）系统（遵循 Vagrant 的提供者，在Debian来宾OS内= = nofollow noreferrer>这些指令来安装Apache Metron开发环境。

Now I am trying to deploy a CentOS (guest) system (following these instructions to install an Apache Metron dev environment) inside the Debian guest OS, using VirtualBox 5.0 as a provider to Vagrant.

我运行：

vagrant up

并收到以下输出：

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吗？

Does anybody know what is going on?

注意：此处的许多帖子建议关闭Hyper-V。我实际上尝试在Dell上执行此操作，但在BIOS中找不到它。我也不认为这会有所帮助，因为问题出在来宾的来宾 ...

Note: Many posts here suggest to turn off Hyper-V. I actually tried to do that on my Dell, but could not find it in the BIOS. Neither do I think that it would help, since the problem is in the guest of the guest ...

推荐答案

事实证明（目前）不支持VirtualBox内部的VirtualBox： https://www.virtualbox.org/ticket/4032

It turns out that VirtualBox inside VirtualBox is not supported (yet): https://www.virtualbox.org/ticket/4032
