Fix Docker Virtual Box VT-x is not available (VERR_VMX_NO_VMX)
tip
There are three common culprits for the type of error the user is seeing
- VT-x is not enabled in the BIOS
- The CPU doesn't support VT-x
- Hyper-V virtualization is enabled in Windows
Since the user already eliminated the first two possible culprits, the next step is to open a command prompt as administrator and run the following command
dism.exe /Online /Disable-Feature:Microsoft-Hyper-V
Afterwards, reboot the PC and try VirtualBox again
