我使用的是 Windows 10 专业版，并成功安装了 Docker Client 18.09.0 并获取了 hello-world docker 镜像。
但是当我尝试使用 docker run 在容器中运行图像时，出现以下错误
C:\Program Files\Docker\Docker\Resources\bin\docker.exe: Error response from daemon: CreateComputeSystem 7b206637bedeb11c5f4bb8a5c12f941da3980a5c0e6e18d823f3323b6640a9de: The virtual machine could not be started because a required feature is not installed.

我不确定该问题的具体情况或未安装哪些功能。当我在互联网上搜索时，所有错误都与我的环境中存在的 hyperv 有关。我的 docker info 顺便提供了以下详细信息:

最佳答案
以防万一有人像我一样使用 Windows 10 虚拟机，您可以在 power shell 中使用以下命令。
Set-VMProcessor -VMName my_virtual_machine -ExposeVirtualizationExtensions $true
记住在执行命令之前以管理员身份运行，否则会出现错误，提示您没有权限。
