在 Vagrant 客户机上启用 Intel VT-x

我正在运行 OSX Mavericks，并且我知道硬件虚拟化已启用。我在 Vagrant 中有一个 debian VM，其中有一个支持硬件虚拟化的虚拟 CPU，但 vmx 标志被禁用。这是一个问题，因为我想在我的 debian VM 中使用 KVM。我需要做什么才能在 debian 客户机操作系统上启用（虚拟）硬件虚拟化？作为参考，cat /proc/cpuinfo 的输出如下：

Virtualbox 不支持嵌套虚拟化，因此您无法使用它来做您想做的事情。但是 VMWare Fusion (OS X) 和 VMWare Workstation (Linux/Windows) 支持此功能并允许您启用嵌套虚拟化：

查看示例（注意 vmx 标志）：

    default: -- /Users/michael/GigaSpaces/VagrantLab/tmp2: /vagrant
==> default: Machine already provisioned. Run `vagrant provision` or use the `--provision`
==> default: to force provisioning. Provisioners marked to run always will still run.

以下是此设置的简短 Vagrantfile：

VAGRANTFILE_API_VERSION = "2"

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
  config.vm.box = "puppetlabs/ubuntu-14.04-64-nocm"
  config.vm.provider "vmware_fusion" do |v|
    v.vmx["vhv.enable"] = "TRUE"
  end
end
