issues:
Failed to open a session for the virtual machine ubuntu.
Raw-mode is unavailable courtesy of Hyper-V. (VERR_SUPDRV_NO_RAW_MODE_HYPER_V_ROOT).
Resul
To check the status of Hyper-v in Windows 10,
right click <"start"> → Run → OptionalFeatures.exe, → look for the "Hyper-V" option.
The box should be empty, not checked or shaded.
Make sure to fully power down and reboot the host after changing the Hyper-v setting.
PS
Docker known for activating this "Hyper-V" without asking for user opinion and then Oracle VirtualBox does not want to work.
