BIOS中未启用虚拟化? [英] Virtualization not enabled in BIOS?

问题描述

当我在Genymotion中启动多核虚拟设备时，得到以下信息:

When I start a multi-core virtual device in Genymotion, I get this:

什么是虚拟化技术?如何启用它?

What is this virtualization technology and how can I enable it?

我的CPU:Intel Core i5-4440

My CPU: Intel Core i5-4440

推荐答案

在打开计算机时，必须在BIOS设置中将其打开.并非所有的BIOS都看起来像此屏幕截图，但这是您要查找的内容的一个示例:

You'll have to turn it on in your BIOS settings as you're turning on your computer. Not all BIOS look like this screenshot, but this is one example of what you're looking for:

Enabling Intel VT-x and AMD-V virtualization hardware extensions in BIOS

本节介绍如何识别硬件虚拟化扩展并在禁用时在BIOS中启用它们.

This section describes how to identify hardware virtualization extensions and enable them in your BIOS if they are disabled.

可以在BIOS中禁用Intel VT-x扩展.某些笔记本电脑供应商默认在其CPU中禁用了Intel VT-x扩展.

The Intel VT-x extensions can be disabled in the BIOS. Certain laptop vendors have disabled the Intel VT-x extensions by default in their CPUs.

无法在BIOS中为AMD-V禁用虚拟化扩展.

The virtualization extensions cannot be disabled in the BIOS for AMD-V.

有关启用禁用的虚拟化扩展的说明，请参阅以下部分.

Refer to the following section for instructions on enabling disabled virtualization extensions.

验证虚拟化扩展已在BIOS中启用. Intel VT或AMD-V的BIOS设置通常在芯片组或处理器菜单中.菜单名称可能与本指南有所不同，虚拟化扩展设置可以在安全设置或其他非标准菜单名称中找到.

Verify the virtualization extensions are enabled in BIOS. The BIOS settings for Intel VT or AMD-V are usually in the Chipset or Processor menus. The menu names may vary from this guide, the virtualization extension settings may be found in Security Settings or other non standard menu names.

1. 重新启动计算机，然后打开系统的BIOS菜单.通常可以通过按 delete 键，F1键或Alt和F4键来完成此操作，具体取决于系统.

1. Reboot the computer and open the system's BIOS menu. This can usually be done by pressing the delete key, the F1 key or Alt and F4 keys depending on the system.

在BIOS中启用虚拟化扩展

注意
以下许多步骤可能会有所不同，具体取决于您的主板，处理器类型，芯片组和OEM.请参阅系统随附的文档，以获取有关配置系统的正确信息.

Note
Many of the steps below may vary depending on your motherboard, processor type, chipset and OEM. Refer to your system's accompanying documentation for the correct information on configuring your system.

打开处理器子菜单.处理器设置菜单可能隐藏在芯片组，高级CPU配置或北桥中.

            a. Open the Processor submenu The processor settings menu may be hidden in the Chipset, Advanced CPU Configuration or Northbridge.

b.启用 Intel虚拟化技术(也称为Intel VT-x). AMD-V 扩展不能在BIOS中禁用，而应该已经启用.根据OEM和系统BIOS，这些虚拟化扩展可以标记为虚拟化扩展，Vanderpool 或其他各种名称.

            b. Enable Intel Virtualization Technology (also known as Intel VT-x). AMD-V extensions cannot be disabled in the BIOS and should already be enabled. The virtualization extensions may be labeled Virtualization Extensions, Vanderpool or various other names depending on the OEM and system BIOS.

c.如果可用，请启用Intel VT-d或AMD IOMMU. Intel VT-d和AMD IOMMU用于PCI设备分配.

            c. Enable Intel VT-d or AMD IOMMU, if the options are available. Intel VT-d and AMD IOMMU are used for PCI device assignment.

d.选择保存并保存退出.

1. 重新启动计算机.

1. Reboot the machine.

启动计算机后，运行cat /proc/cpuinfo |grep -E "vmx|svm".指定--color是可选的，但在要突出显示搜索词时很有用.如果命令输出，则虚拟化扩展现在已启用.如果没有输出，则您的系统可能没有启用虚拟化扩展或未启用正确的BIOS设置.

When the machine has booted, run cat /proc/cpuinfo |grep -E "vmx|svm". Specifying --color is optional, but useful if you want the search term highlighted. If the command outputs, the virtualization extensions are now enabled. If there is no output your system may not have the virtualization extensions or the correct BIOS setting enabled.
