Mac使用Parallels Desktop14虚拟机win10安装Docker，开启VT-X/AMD-v

window下载Docker地址：http://mirrors.aliyun.com/docker-toolbox/windows/docker-toolbox/

使用Parallels Desktop虚拟机WIN10安装完成Docker后，提示需要开启VT-X/AMD-v：

Error with pre-create check: "This computer doesn't have VT-X/AMD-v enabled. Enabling it in the BIOS is mandatory"

解释方法

1.在win10关闭状态下，配置--硬件--CPU与内存--高级设置--勾选启动nested虚拟化/PMU虚拟化

2.重新打开�Docker Quickstart Terminal后，发现还是运行不了，缺少boot2docker，但有提示重新下载，可手动下载后，替换到提示地址（C:/Users/Asen/.docker/machine/cache/）

Running pre-create checks...
(default) Image cache directory does not exist, creating it at C:\Users\Asen\.docker\machine\cache...
(default) No default Boot2Docker ISO found locally, downloading the latest release...
(default) Latest release for github.com/boot2docker/boot2docker is v19.03.12

或等自动下载好即可

最后安装成功

【注意】

双击Docker Quickstart Terminal时，提示错误：

Starting "default"...
(default) Check network to re-create if needed...
(default) Windows might ask for the permission to configure a dhcp server. Sometimes, such confirmation window is minimized in the taskbar.

解决方法：只需要打开Docker Quickstart Terminal时，只需要右击，使用以管理员身份运行即可
