virtual-machine - VT-x 不可用且 Windows 10 上没有 Hyper-V 管理器

Question

当我使用 vagrant up 启动 VM 时，我发现以下 error ox80004005(注意我使用 Oracle VM Virtualbox 进行虚拟化)

kayan@kayan-VirtualBox:~/vagrant/rpm$ vagrant up
Bringing machine 'default' up with 'virtualbox' provider...
==> default: Checking if box 'jhcook/fedora27' is up to date...

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

Command: ["startvm", "769fc6c1-ea8d-46d8-8a7b-16989540d530", "--type", "gui"]

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

Screenshot: VT-x isn't available ERROR

我使用的是 64 位 Windows 10。我的处理器是 Intel(R) Core(TM) i7-7500U CPU @ 2.70 GHz。

为了解决这个错误，有人建议我应该在我的 Windows 主机上禁用 Hyper -v。当我选择禁用 Hyper-v 功能时，我发现我的机器中没有 Hyper-v(奇怪!!!)

Screenshot: No option to enable or disable Hyper-v

然后我使用这个命令 dism.exe/Online/Enable-Feature:Microsoft-Hyper-V/All 来禁用管理程序，我发现了这个(注意:我以管理员身份运行 CMD)。

如果您在 Windows 10 Founder's Update 之后在 VirtualBox 中遇到问题，您需要再次关闭 Core Isolation Memory Integrity。用户界面有问题，这是可以通过以下方式完成的。注册表，导航到下面并设置为0:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceGuard\Scenarios\HypervisorEnforcedCodeIntegrity\Enabled
