我在Windows 7上安装了VirtualBox 5.1。 我有一个客户操作系统Debian（64位）设置。 对于此guest虚拟机系统，我在“系统 - Accelaration”中选中了“启用VT-x / AMD-V ”和“启用嵌套分页”复选框em>“menu和” Paravirtualization Interface “设置为” KVM “。
现在我尝试使用VirtualBox 5.0作为提供程序在Debian客户操作系统内部署CentOS（来宾）系统（遵循these 指令安装Apache Metron开发环境）到 Vagrant 。
我跑：
vagrant up
并收到以下输出：
ytsboe@debian-metron ~/incubator-metron/metron-deployment/vagrant/full-dev-platform$ vagrant up

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吗？
注意：此处有很多帖子建议关闭Hyper-V。我实际上试图在我的戴尔上做到这一点，但在BIOS中找不到它。我也不认为它会有所帮助，因为问题出在 guest 的 guest 中......
