许多用户在尝试执行相同操作时无法启动 VM，然后收到以下错误消息 -

Failed to open a session for the virtual machine.
Raw-mode is unavailable courtesy of Hyper-V.
(VERR_SUPDRV_NO_RAW_MODE_HYPER_V_ROOT).

在本文中，我们将借助一些简单的解决方案来修复错误。

^(Raw-mode)由于Hyper-V VirtualBox^{(Hyper-V VirtualBox)}错误，原始模式不可用

这些是你可以做的事情来修复原始模式由于 Hyper-V^{(Raw-mode is unavailable courtesy of Hyper-V)} VirtualBox 错误而无法使用。

1. 禁用 Hyper-V
2. 禁用管理
3. 关闭核心隔离
4. 启用虚拟化

让我们详细谈谈它们。

1]禁用Hyper-V

从错误消息本身非常明显，Hyper-V是此错误背后最常见的原因之一。Hyper-V 用于大多数第三方 VM 软件在Windows 操作系统^{(Windows OS)}上创建虚拟机，包括不使用它的VirtualBox 。因此，最好禁用此功能以确保系统稳定。

您可以按照给定的步骤在Windows 10计算机上禁用Hyper-V 。

1. 从 开始菜单^{(Start Menu.)}启动控制面板。^{(Control Panel )}
2. 单击 Programs and Features > Turn Windows features on or off.
3. 取消 勾选Hyper-V 并选择确定。

现在，重新启动计算机并检查问题是否已解决。

2]禁用HyperVision

如果您是第三方 VM，例如Virtualbox，您将看到Hypervision是否设置为 Auto。因此，我们需要运行命令来检查它是否设置为Auto，如果是，我们将禁用它。

为此，请 从 Start Manu 启动^{(Start Manu )}命令提示符 ^{(Command Prompt )}并执行以下命令。

bcdedit

如果 hypervisionlaunchtype 为 Auto， 请运行以下命令将其关闭。否则，跳过此步骤。

bcdedit /set hypervisorlaunchtype off

现在，重新启动计算机并检查问题是否仍然存在。

3]关闭核心隔离

核心隔离^{(Core Isolation)}是一个额外的基于虚拟化的安全层。它可以阻止您的计算机免受恶意软件攻击。但是，它的问题是会干扰Virtualization，特别是如果您使用第三方工具，例如VirtualBox。那么，让我们看看如何禁用它并修复错误。按照给定的步骤执行相同的操作。

1. 通过 Win + I.启动 设置 。^(Settings )
2. 单击 Update & Security > Windows Security > Device Security.
3. 单击 核心隔离详细信息。^{(Core Isolation details.)}
4. 禁用 内存完整性^{(Memory integrity)}

现在，重新启动计算机，看看问题是否得到解决。

4]启用虚拟化

如果不起作用，请检查您的计算机的虚拟化是否已启用^{( check if the virtualization of your computer is enabled)}。如果没有，请启用它并检查问题是否仍然存在。

Raw-mode is unavailable courtesy of Hyper-V VirtualBox error

Many users are unable to boot VM as when they try to do the same, then receive the followіng error message-

Failed to open a session for the virtual machine.
Raw-mode is unavailable courtesy of Hyper-V.
(VERR_SUPDRV_NO_RAW_MODE_HYPER_V_ROOT).

In this article, we are going to fix the error with the help of some simple solutions.

Raw-mode is unavailable courtesy of Hyper-V VirtualBox error

These are the things you can do to fix Raw-mode is unavailable courtesy of Hyper-V VirtualBox error.

1. Disable Hyper-V
2. Disable Hypervision
3. Turn off Core Isolation
4. Enable Virtualization

Let us talk about them in detail.

1] Disable Hyper-V

Pretty evident from the error message itself, Hyper-V is one of the most common reasons behind this error. Hyper-V is used to create Virtual Machines on Windows OS by most third-party VM software, including VirtualBox, which don’t use it. Therefore, it is better to disable this feature to make sure that the system is stable.

You can follow the given steps to disable Hyper-V on a Windows 10 computer.

1. Launch Control Panel from the Start Menu.
2. Click Programs and Features > Turn Windows features on or off.
3. Untick Hyper-V and select Ok.

Now, restart your computer and check if the issue is fixed.

2] Disable HyperVision

If you are a third-party VM, such as Virtualbox, you will see if Hypervision is set to Auto. Therefore, we need to run commands to check if it’s set to Auto, if it is, we will disable it.

To do that, launch Command Prompt from the Start Manu and execute the following commands.

bcdedit

If hypervisionlaunchtype is Auto, run the following command to turn it off. Otherwise, skip this step.

bcdedit /set hypervisorlaunchtype off

Now, reboot your computer and check if the issue persists.

3] Turn off Core Isolation

Core Isolation is an extra layer of virtualization-based security. It is there to stop your computer from malware attacks. However, the problem with it is that interferes with Virtualization, especially, if you use third-party tools such as VirtualBox. So, let us see how to disable this and fix the error. Follow the given steps to do the same.

1. Launch Settings by Win + I.
2. Click Update & Security > Windows Security > Device Security.
3. Click Core Isolation details.
4. Disable Memory integrity

Now, restart your computer and see if the issue gets fixed.

4] Enable Virtualization

If nothing works, check if the virtualization of your computer is enabled. If not, enable it and check if the issue persists.
