Here‘s the solution:
1) Open command prompt as administrator

2) paste the following command:
dism.exe /Online /Disable-Feature:Microsoft-Hyper-V
3)Then reboot.
VMMR0_DO_NEM_INIT_VM failed: VERR_NEM_MISSING_KERNEL_API_2 (VERR_NEM_MISSING_KERNEL_API_2).
VT-x is not available (VERR_VMX_NO_VMX).
我还是以Virtualbox为主吧，毕竟在里面也能用linux 的 docker.
Virtualbox will get upset and not run if Microsoft Hyper-V is enabled.
Here‘s the solution:
1) Open command prompt as administrator
search for ‘command‘
right-click then select ‘run as administrator‘
2) paste the following command:
dism.exe /Online /Disable-Feature:Microsoft-Hyper-V

Virtualbox 和 Docker Desktop 不能在Widnows上共存。
