Windows 10系统VirtualBox无法进入系统,日志报错“HM: HMR3Init: Attempting fall back to NEM: VT-x is not available”

Windows 10上使用 Linux 子系统的时候,无法成功启用。根据官方文档 旧版 WSL 的手动安装步骤 之后,依旧没效果,反倒是VirtualBox无法进入系统了。

观察日志,报错信息如下:

Intel CPU

{timestamp} HM: HMR3Init: Attempting fall back to NEM: VT-x is not available
{timestamp} NEM: WHvCapabilityCodeHypervisorPresent is TRUE, so this might work...

AMD CPU

{timestamp} HM: HMR3Init: Attempting fall back to NEM: AMD-V is not available
{timestamp} NEM: WHvCapabilityCodeHypervisorPresent is TRUE, so this might work...

解决方案如下:

1.使用管理员启动命令行.

2. 执行如下命令:

bcdedit /set hypervisorlaunchtype off

某些电脑需要额外执行如下命令:

DISM /Online /Disable-Feature:Microsoft-Hyper-V

3. 重启电脑
